UK Based Food Factory Installs Panasonic CO2 Commercial Refrigeration to Cool and Freeze Sushi

UK

CO2, Cold Chain

Tanpopo Japanese Food, a UK-based food wholesaler, has recently equipped its warehouse in Feltham, West London, with condensing units from the Panasonic CO2 Cold Chain range. The units were installed by Versan Ltd of Chertsey, Surrey, a company that specialises in the installation of refrigeration technology.   For over 20 years, Tanpopo has been making and supplying sushi to catering companies, supermarkets, hotels, stadia and event organisers across the UK. With the use of renewable technology and reliability high on the agenda for Tanpopo, Panasonic’s Cold Chain Commercial Refrigeration range, which uses environmentally-friendly CO2, was the ideal choice for all their frozen and chilled food storage refrigeration requirements when the business moved to its new premises in Feltham.   Peter Bigmore, Owner of Tanpopo Japanese Food Ltd, commented, “After extensive trialling of another competing product, we chose the Panasonic solution because of its environmentally-friendly credentials.  Other key factors were the range’s reliability, the fact the units are compatible with a range of control systems and due to the low charge of CO2 required by the units, no additional leak detection equipment was necessary for this application.”   A further challenge for this installation was that the cooking and manufacturing process in the factory results in ambient temperatures of up to 43oC, so any refrigeration units chosen must be able to operate efficiently even in these extreme conditions. Fortunately, this is one of the unique benefits of the Panasonic units, which can operate efficiently at this temperature, and thus provides additional confidence in the technology of the product.   The Panasonic CO2 Cold Chain units are suitable for both refrigerated and freezer showcases, as well as walk-in freezers and cold rooms – offering a solution for all commercial refrigeration needs. The technology has been specifically developed for small to medium capacity applications within the retail and food service sectors. The range available in the UK features units for medium temperature (4kW to 16kW) and low temperature (2kW to 8kW) condensing units.  Additionally, the 16kW (10HP) units can be connected to provide up to 32kW cooling capacity at medium temperature.   Launched in Japan in 2010, the range has 10 years’ experience in projects within Japan and was first launched in the UK in 2018. The key benefits and factors to the success of the units is due to the reliability, the compact size, the unique two stage compressor, the easy installation and the use of the natural refrigerant CO2. Furthermore, the units are compatible with a range of different control systems.   In July 2019, Versan Ltd commissioned and has currently installed four Panasonic 2kW CO2 units at Tanpopo Japanese Food Ltd’s premises in Feltham that replaced four of the R404 systems, two in the low temperature cold rooms at -30°C and two serving as medium temperature chillers at -4°C.  Due to the advice from Versan Ltd and their experience of CO2, further units are due to be installed to replace all the current R404 systems at the premises.  Each of the Panasonic units is used to either freeze or chill the products produced in the sushi factory, that are then stored prior to them being shipped to supermarkets around the UK.   Xavier Debray, Managing Director of Versan Ltd commented, “One of the pre-requisites for many supermarket chains now is to review their supply chain and their green credentials, such as the use of renewable technology during their processes. The Panasonic units use CO2, a very attractive natural alternative to conventional refrigerant gases.   CO2 has a zero ODP (Ozone Depletion Potential) and a GWP (Global Warming Potential) equal to 1 (compared to a refrigerant like R404A with a GWP of 3922).”   Xavier has a keen interest in renewable and sustainable technology and in particular the use of CO2 and adds, “I studied the use of CO2 as a refrigerant some years ago when at University and was thrilled after recent research that manufacturers such as Panasonic are now embracing this technology and have developed a reliable commercial refrigeration range that uses CO2.  Some of Tanpopo’s partners are also Japanese and really liked the fact that the technology from Panasonic has originated and been proven in projects for over a decade in Japan. Furthermore, the unique benefit of the Panasonic range is being able to easily switch from either freeze or chill mode.”   Indy Tharnvithian, Technical Specialist for CO2 at Panasonic added “When installing the Panasonic CO2 range, just two settings are required – vacuum mode and evaporating setting – everything else is pre-set. Obviously if need be, settings can easily be modified with alarms that will indicate any wrong settings. If installers register on the Panasonic Pro-Club website, they will have access to free commissioning tools that includes a cooling capacity calculator, pipe calculator and EEV quick selection tool.”   Xavier further explained that, “As Versan Ltd were one of the first to commission and install the Panasonic units in the UK, we were originally a little bit apprehensive, but found that by working with Indy, Technical Specialist at Panasonic, onsite during the design and commissioning stage, plus throughout the process, helped to make the process easier. In fact, we were pleasantly surprised by how easy the units were to install and how reliable the units have been since installation. So much so that Tanpopo are looking to install further units.”

Founded in 1871 as Cumberland Valley State Normal School, the university serves the educational, cultural, and social needs of students not only from throughout Pennsylvania but also from other states and from overseas. Shippensburg currently has a student base of around 7,000 full-time undergraduates and 1,300 full-time graduates, taught by around 300 full-time and 130 part-time academic staff. Since 1985, many of the university’s original historic buildings have been listed on the National Register of Historic Places.

An Ideal Choice for Educational Institutions
A Panasonic VRF system was recently installed in one of Shippensburg’s student residences. Having earlier considered a four-pipe hydronic system, the university found the Panasonic solution to be more cost effective. The system allows each dormitory room to be heated or cooled as needed, and heat recovery makes the entire building highly energy efficient. Panasonic’s local representative, Envirocon Associates, Inc., designed and implemented the project. As well as ensuring correct installation, Envirocon performed extensive system diagnostics and programming. Shippensburg’s satisfaction is evident in its plans to install Panasonic ECOi VRF systems in three further buildings.

DDD Pharmaceuticals

UK

Sistem vrf, Others

ECOi

Background: Controlled temperature and monitoring is a necessity for any facility dealing with pharmaceutical storage and manufacturing processes. DDD Pharmaceuticals’ new site in Watford not only required controlled cooling for the warehouse, but also heating and cooling facilities for the offices at the plant.

Project Challenge:
 DDD Pharmaceuticals provides a complete service for manufacturing pharmaceutical products for clients in the health and beauty sectors. As with most pharmaceutical products, to maintain the safety, performance and efficiency of a product, the environment in which the item is manufactured, stored and distributed must be carefully maintained.  With around 15-tonnes of product on-site, a reliable solution was required.

Solution: 
For the manufacturing and storage phase at DDD, Panasonic’s new ECOi VRF range was specified as the ideal solution for the plant. Seven 16kW cooling only cassettes were installed in the pharmaceutical facility, with a further five to heat and cool in the offices, all piped from the same outdoor units.

Building Energy analysis: 
To meet the requests of DDD, TF Solutions opted to use Panasonic’s ECOi outdoor units with the indoor cassettes. The units are able to achieve an incredible COP performance of up to 4.04 when cooling and 4.56 whilst heating – giving excellent savings. The installation also makes the site compliant of the R22 regulations.

3rd Party Comments:
 “The requirement at DDD, although not unique, was somewhat complex” explains John Wakefield, designer of the HVAC installation at DDD. “Whilst constant and recordable conditions were required in the pharmaceutical storage and manufacturing facilities, we also needed a system that could provide adjustable heating and cooling to other onsite amenities. The Panasonic solution allowed for us to combine both these needs into one system, allowing for simultaneous operations whilst only requiring one set of outdoor units.”

ECOG

Hinkley, UK
Type of project: Refurbishment

Installer Company: Pick Everard.
Year installation: 2012

Background: 
The ailing chiller system serving the National Grid’s Hinckley critical call centre needed to be replaced.  National Grid needed a reliable and cost-effective solution.

Project Challenge:
 The Hinckley plant houses the highly important gas leak call centre that runs 365 days a year, 24 hours a day. It was crucial for the system to not only be dependable, but also be highly energy efficient.

Solution: 
The Pansonic ECO-G system installed allowed for more efficient control and performance. The National Grid site’s existing system of two chillers was replaced by seven Panasonic ECO-G’s. This technique of using multiple systems provides a much higher resilience compared to only one or two units. If a fault in one arises, the combination of heat pumps ensures that it is able to provide continuity of service.  

Building Energy analysis: 
The new ECO-G system installed on site has been a very straight forward transition. Not only do the units provide continuous service to the site, they have also allows the costs involved in running the units to be significantly reduced.    

3rd Party Comments:
 “The ECO-G system installed allowed for more efficient control and performance,” explains Jeff Fleming from Pick Everard, installers of the project. “With the highest reliability rate, the ECO-G ensures individual and efficient control and performance. This is a far more convenient method, and reduces the overall consumption of the unit, removing unnecessary wastage that would result from more traditional air conditioning systems.”

Hotel Claris 5 * GL

Spain

Sistem vrf, Hotels

ECOi 3w

Background
Housed in a building built in the year 1883, neoclassical style, was one of the first palaces that were built in one corner of the District of l'Eixample in Barcelona. The 5* Grand Luxe hotel, which opened its doors in 1992, integrates the façade of the old palace with a modern glass structure. In 2012 the building replaced its existing air-conditioning system with Panasonic’s ECOi system. The 120-room hotel also has a gallery of Egyptian art from the collection of Jordi Clos.

Challenge of the project
The challenge presented by this project was to replace an existing VRF system without affecting the normal activity of hotel. The main objectives were to reduce running costs, provide a more comfortable atmosphere with more precise temperature control, and quieter operation for guests. In addition, the property required excellent after-sales service, 24 hours a day, 365 days a year.

The solution
The heat recovery system is ideal for a hotel of this category. A smart combination of 2 pipe and heat recovery units significantly reduced the investment costs, without affecting the requirements of comfort. Thanks to the modularity of the system ECOi, the installation was performed plant-by-plant without affecting the normal activity of hotel.

Control
The integrated system control was provided by the KNX/EIB interface and in addition, a central touch panel with web server (CZ-256ESMC2) was installed for centralized system control

Café 40

Spain

Sistem vrf, Restaurants

ECOg


Background
40 Café is the first café restaurant belonging to Los 40 Principales, in Spain's popular music radio station. The installation is within the basement of an old building in one of the busiest streets of Madrid. 40 Cafe, aims to become a new icon of nightlife in Madrid.

Challenge of the project
There were several challenges to implementing this project. The first was the power limitation in the building. Despite being in the Centre of Madrid, there was a restriction on power to run conventional HVAC installation. Another major challenge was the opening date. The tight deadline was a requirement to meet the demand of the owners. Outdoor units were installed at roof level with the help of a crane. Due to the limitations of restricting Street access and the imposition to residents of the building, the external installation was carried out in just one day available prior to opening.

The solution
ECOg, the gas powered VRF, was the ideal solution to overcome the power limitation of the area. The system combines seamlessly with Panasonic’s VRF indoor units and allows additional connection to a hydronic system. Panasonic pledged delivery of the units for the only day in which the crane could be used, in spite of the fact that the systems still had to be produced. The installation date was
just 2 months after being awarded the project. This was all made possible thanks to the involvement of various departments as well as Senior Management, highlighting Panasonic’s commitment to meet customer needs.

Control
A touch panel with PAIMS management (CZ-256ESMC2), was installed for centralized air conditioning system control, including PC software and web server interface.

Bergås Terasse

Norway

Sistem vrf, Residential

ECOi


System: 2-way ECOi system, 6 O/U 
Inst. capacity: 3x76 kW (heating) 3x16 kW (hot water)
Owner: 
Block Watne AS, new installation in Drammen (Norway) 
Year Installation: 2013 

Background:
  Bergås Terasse is a new condominium complex, under construction in the outskirts of Drammen, some 50 km west of Oslo. It consists of three block buildings with 14 apartments each and a common garage underneath. The first families will move in into the apartments in the summer of 2013.

Project Challenge: 
Norwegian regulations prohibits the use of oil or gas heating, or electrical radiators for heating new houses. It also stipulates that a minimum of 60 per cent of the energy consumption has to come from alternative/renewable sources. District heating was not an alternative, as it isn’t available at the location. And a geothermal energy system was too expensive.

Solution: An air-to-air heat pumps provide the heating, and is combined with a heat recovery system. Each of the apartments has its own duct unit. There is also an additional four wallhanged units per house for the common areas (entrances and staircases). The hot water is produced with air-to-water heat pumps. The outdoor units are placed in separate building, to reduce noise, save valuable indoor space and facilitate service.

Building Energy analysis:  The houses are built according to the very strict Norwegian building code TEK10, and have very low energy consumption for room heating and production of hot water.

Control: Panasonic Intelligent control with energy distribution for central controller, with web setting for monitoring from distance. Each apartment has a Panasonic Simplified controller installed.

3rd Party Comments: Mr. Niklas Kiiveri   (EcoConsult A/S, Project manager company):   There have been many difficulties under way in this project, but so far they have all been solved during the process. There is no other project in the Nordics to compare with, so with help from Panasonic we went out in Europe to find one that was as alike as possible. We also had to build up a “new” in house faculty understanding parallel to the plumbing, electrical, ventilation and carpenter competences already well-established in the construction team. The buildings might also need place for a cooling system. But our first opinion is that the VRF system absolutely is here as a viable solution for the future building culture in the Nordics.

Pompă de căldură aquarea aer-apă, Restaurants

AQUAREA

Specifying company: Oceanair
Installer Company: FWP Air Conditioning
Year installation: 2012

Background: 
Carluccio’s restaurant wanted to install a system which would provide the desired volume of hot water, at the correct temperature while at the same time reduced energy costs.

Project Challenge:
 Following a consultation with Carluccio’s, it was decided that their new site in the Meadowhall shopping centre in Sheffield would be the ideal location as it had the correct attributes for the installation of an air to water heat pump system.  Previous restaurants in the chain had been fitted with a more traditional 12kW boiler system.

Solution:
 FWP installed a 12kW Aquarea T-CAP mono bloc unit which would allow  for the free air from the kitchen roof space to be transferred through condensing unit providing hot water at the optimum temperature.  With a high coefficient of performance (COP), for every kW of electricity the system uses, it provides 4kW of energy. This makes the Aquarea far more cost effective than a conventional heating system.

Building Energy analysis: When Carluccio’s compared the Sheffield site to one of their existing restaurants of a similar size, the energy savings were considerable.  To heat the water for their Leeds restaurant cost £3782 whilst at the Meadowhall site the comparable cost was just £951. These sizable savings mean the site will see a return on investment in about 2 years and has achieved a COP of about 3.91.

3rd Party Comments:
 Alison Stanton, Development Director from Carluccio’s said: “We strive for sustainability wherever possible right across our business and were keen to trial air to water heat pumps at our new Sheffield restaurant. The results of the trial show us that we can achieve significant savings on our energy costs as well as reducing our carbon footprint.  We hope to now install Aquarea units at all of our new developments and potentially retro fit ASHPs to our existing 50 restaurants.
