The refrigeration basics and refrigeration cycle


1. The common refrigeration basics

Major terms: temperature, heat, specific heat, sensible heat, latent heat, pressure, evaporation, boiling, thermal conductivity, convective heat transfer coefficient, heat transfer coefficient, heat emission coefficient, density, humidity, enthalpy, entropy, and diagram of pressure enthalpy.


2. The Refrigeration Cycle

Refrigeration system fundamental components:

  1. The compressor
  2. The condenser
  3. The metering device
  4. The evaporator
  5. The receiver


The Refrigeration Cycle

  1. The refrigerant enters the compressor as a warm, saturated low-pressure gas, leaves the compressor as a superheated (hot) high-pressure gas,
  2. And then enters the condenser as a superheated (hot) high-pressure gas, leaves the condenser as a regular temperature, saturated high-pressure liquid,
  3. The refrigerant enters the evaporator as a cold, low-pressure liquid, leaves the evaporator as a warm, saturated low-pressure gas.

How to use the cold room to reduce vegetable loss? - CRYO SYSTEMS refrigeration Vegetable loss happens during fruit gathering, storing, transportation and sale every time. But how to avoid loss? 1. The first way is Pre-test precooling Now we need to know the main reasons for the loss of vegetables: Microbial infection:  In infected vegetables, micro-organisms are mainly fungi and bacteria, these micro-organisms are from some vegetables and farmland, such as potato late blight, carrot sclerotia, radish black rot, sick vegetables can Continue to spread hazards; some micro-organisms in the storage and transportation or even sales began to endanger the vegetable products, these microorganisms are mostly mold and corrupt bacteria, causing vegetables to grow mold, rot, smelly, causing losses. Vegetable physiological and biochemical reactions:  Vegetable harvest after a period of time, there are still breathing and other life activities, which respiration and a variety of physiologic...

  6 Effective Ways to Improve Cold Storage Efficiency As we all know, the electricity consumption of cold storage and cold storage warehouses is generally relatively large, and with the steady rise in electricity costs, it is very important to improve the refrigeration efficiency of cold storage rooms. CRYO is an experienced cold storage construction expert and we thought we’d share some of the most useful and effective ways to maximize the efficiency of your cold room so you don’t waste unnecessary money on your electricity bill. Regular maintenance Maintenance plays a key role in maintaining the energy efficiency of your cold room. Taking the time to do regular inspections and checks of your cold storage can help find and fix problems before the refrigeration system fails. Also, cold storage maintenance should be done by skilled and professional workers. Regularly clean the condenser unit and evaporator coil Both the evaporator coil and the condenser unit are very important to th...

What kinds of cold room maintenance should be considered?

Image
  What kinds of cold room maintenance should be considered? Summer is coming, which means that the cold room will be used more regularly to keep food fresh and frozen, so what should be paid attention to for its maintenance? 1. Electric power for the cold room. Because electric power is used to keep the cold room running, it is important to check the electricity on a regular basis to see if the voltage is stable enough. To make sure the electricity is adequately protected? 2. The evaporator's defrost systems. If the cold room is too humid, the defrost period is set too long, or the room temperature is not properly adjusted, etc. Frost will form on the evaporator. As a result, you must ensure that the correct settings for the defrost period are specified. And, manual defrost should be used if necessary. 3. Clean the condenser. The condenser is usually placed outside, where it might collect dust. Clean the dust as soon as possible so that the whole system can function effectively. ...
