  • What is a ton of refrigeration?

    Commercial refrigeration systems in the US are mostly rated in tons of refrigeration and this term is used widely in other parts of the world. However, outside the US, cooling systems may be normally specified in kW (or MW) or in Btu/h. The roots for refrigeration are in the ice making industry, and the ice manufacturers wanted an easy way of understanding the size of a refrigeration system in ...

  • A study on the exergetic and environmental effects of commercial cooling systems

    This study examines the effects of exergy efficiencies for three different cooling systems used commonly in commercial applications like hypermarkets. Additionally, environmental effects depending on the Total Equivalent Warming Impact (TEWI) in each system are calculated. In the analysis, considered under constant load, R22, R502, R134a, R404a and R507 refrigerants, and R407 and R410 alternative ...

  • Exergetic performance evaluation of ejector cooling system

    Ejector-cooling model is developed to calculate the entrainment ratio and the area ratio representing throat to nozzle area. The developed model is validated with available experimental data in the literature. Parametric studies using the refrigerant R134a as the working fluid show that the Coefficient of Performance (COP) of the system is increased by increasing the generator and evaporator ...

  • Design and Development of a Renewable Cooling and Power Generation Systems

    The key objective of this project is to address the unfulfilled demand for power and cooling in remote, rural, and un-electrified areas and to enhance overall socio-economic conditions through delivery of electricity and improved cold storage facilities using renewable energy. This project seeks to design, develop, and fabricate a number of prototypes with integrated renewable heating and cooling ...

  • Performance evaluation of locality–based compact solar refrigeration system

    Cooling system with low capacity utilising solar power can be widely used for remote and rural cooling applications. This paper describes the trend of solar insolation for a period of one year at Tiruvannamalai town, a district capital in Tamil Nadu state, South India which is geographically located at latitude 12.229 N, longitude 79.076 E. The performance of a compact solar refrigeration system ...

  • Improving energy efficiency: About oil fouling in refrigeration systems

    Introduction Most air conditioning and refrigeration systems have a mechanical compressor which relies upon lubricating oil to function. During the normal course of the refrigeration process, ½% to 8% of the compressor’s lubricating oil is circulated throughout the system along with the refrigerant. Since the early days of refrigeration and air conditioning technology, the ...

  • Refrigerant leak detection is heavily regulated by government agencies

    Refrigerant leak monitoring in refrigeration and air-conditioning (RAC) systems and heating, ventilation and air conditioning (HVAC-R) equipment is very challenging, even for the most skilled HVAC-R technician. The leak could be well concealed from view in tubing, a system component, or in an operating or safety control component. With the Environmental Protection Agency (EPA) laws documented ...

  • Degassing Refrigerators - Drill-head and Piercing-plier

    1. For what purpose do we have to degas a refrigerator? A refrigerator has to be disposed as hazardous waste. The refrigerants inside a hazardous refrigerator are harmful for the environment (ozone depleting and greenhouse effect). Most common refrigerants are; R12, R134a and R600a. The uncommon is the removal of NH3. Refrigerants are developed to dissolve very easily into ...

  • EPA mandates proper refrigerant gas recovery processes

    New EPA regulations require facilities that use air conditioning and refrigeration equipment to have a refrigerant recovery plan in place. The plan is needed to make sure that any harmful gases that might leak are captured. Refrigerant gases contain hydrochlorofluorocarbons, known to cause severe damage to the ozone layer and to promote global warming. A comprehensive plan is now in place to ...
