transport vehicle are of Vapour Compression Refrigeration system (VCRS). This system utilizes power from the engine shaft as the input power to drive the compressor of the refrigeration system‚ hence the engine has to produce extra work to run the compressor of the refrigerating unit utilizing extra amount of fuel. This loss of power of the vehicle for refrigeration can be neglected by utilizing another refrigeration system i‚e. a Vapour Absorption Refrigeration System (VARS). It is

A worldwide ban of CFC could mean that millions of people could not afford refrigerators‚ and millions might die from food poisoning. Is that justified by saving the stratospheric ozone? It is justified because there are feasible alternative refrigeration systems that don’t emit chemical compounds that are harmful to the ozone layer. Less known refrigerants such as ammonia (NH3)‚ Carbon dioxide (CO2) and propane (C3H8) have no impact at all on global warming as well as on the ozone layer. Not only

Gorrie used Evan’s design to build a refrigerator to make ice to cool the air for his yellow fever patients in 1844. Over 30 years later German engineer Carl Von Linde discovered the process of liquefying gas which is part of basic refrigeration technology. From the 1800s until the 1920s‚ refrigerators used toxic gases as refrigerants. With research developed‚ corporations discovered a less dangerous refrigerant called Freon. Freon soon became the standard for almost all home kitchens

SIMULATION STUDIES ON GAX BASED VAPOUR ABSORPTION REFRIGERATION SYSTEM FOR COMBINED DRYING AND STORAGE APPLICATIONS R Sivakumar‚ R Saravanan and Alberto Coronas Extended Abstract India is the second largest producer of fruits and vegetables in the world. In 2010-11‚ fruit production stood at 74.877 million tonnes and vegetables production at 146.554 million tonnes. On the other hand 18% of fruits and vegetables from India are going to waste for want of adequate storage facilities. The amount

example. You are the owner of Oceanarium‚ a fine-dining seafood restaurant in Birmingham‚ Alabama. This morning you discovered that your restaurant’s daily 6:00 a.m. shipment of fresh seafood from Neptune Seafood is spoiled due to a faulty refrigeration unit in the delivery truck. Following your discovery‚ you made an immediate phone call to Neptune to alert them of the situation. You should now send a follow-up e-mail to Carl Bass‚ the shipping manager at Neptune‚ detailing the problem and

process of decaying food would take longer. The fridge contains and stores many different items‚ allowing their users to store – as well as preserve- anything they wanted for extended amounts of time. Inside the fridge lies a freezing chamber‚ a refrigeration chamber‚ a cooling system‚ a cooling circuit‚ and a cooling surface in each of the chambers. With this construction‚ temperature regulation is done by balancing the surfaces of each of the cooling units. Exterior units are made using glass‚ plastic

Refrigerated rail cars‚ also known as reefers‚ are insulated boxcars that keep their cargo at a regulated temperature‚ usually around 2 or 3 degrees Celsius. The first reefers relied on ice to cool their load‚ but now diesel-powered refrigeration units have replaced the ice as a more effective way to cool the load. The refrigerated rail car was patented by J.B. Sutherland in Detroit‚ Michigan in 1867. He designed an insulated car with ice at either end. This allowed air to come in from the top‚ pass

Air Conditioning Systems An air conditioning‚ or HVAC&R‚ system is composed of components and equipment arranged in sequence to condition the air‚ to transport it to the conditioned space‚ and to control the indoor environmental parameters of a specific space within required limits. Most air conditioning systems perform the following functions: 1. Provide the cooling and heating energy required 2. Condition the supply air‚ that is‚ heat or cool‚ humidify or dehumidify‚ clean and purify‚ and
