What are the basics of refrigeration?

The 4 Main Refrigeration Cycle Components

  • The compressor.
  • The condenser.
  • The expansion device.
  • The evaporator.

What are the 4 stages of refrigerant?

The Four Stages of Your Refrigerant Cycle

  • Stage 1: Evaporator Coil. Your refrigerant’s journey begins at your evaporator coil, which is located inside the indoor unit in your home.
  • Stage 2: Compressor.
  • Stage 3: Condenser Coil.
  • Stage 4: Expansion Chamber.

What are the types of refrigeration system?

4 Types of Refrigeration Systems

  • Evaporative Cooling. Evaporative cooling units are also referred to as swamp coolers.
  • Mechanical-Compression Refrigeration Systems. Mechanical compression is used in commercial and industrial refrigeration, as well as air conditioning.
  • Absorption.
  • Thermoelectric.

What is the cycle of refrigeration?

Principles of Refrigeration For this reason, all air conditioners use the same cycle of compression, condensation, expansion, and evaporation in a closed circuit. The same refrigerant is used to move the heat from one area, to cool this area, and to expel this heat in another area.

What is pressure in refrigeration?

Most technicians in the HVAC field know the normal range of operation for the low-pressure side of an air conditioning system. This tends to be around 60 PSI to 85 PSI for R-22 and 105 PSI to 143 PSI for R-410A and is dependent upon operating conditions.

What is the unit of refrigeration?

Ton of refrigeration
Unit of refrigeration: Unit of refrigeration is TR (Ton of refrigeration). It is the amount of heat which is required to extract from one tonne of water at 0°C in order to convert it into equivalent ice at 0°C in a day.

What is liquid line in refrigeration?

The larger line typically carries a cool gas and is insulated. This is commonly referred to as the suction line, but it is also called the return line or vapor line. The smaller uninsulated line typically carries a warm liquid. It is most often called the liquid line.

Why refrigerant is compressed?

To cool a room down, you need to collect the heat and dump it somewhere else. The air in this “somewhere else” must be a lower temperature than the refrigerant for you to be able to dump the heat. To make sure this is possible, the refrigerant is compressed so that the temperature increases.

What is refrigeration efficiency?

Refrigeration efficiency is measured in terms of the Coefficient of Performance (COP) – the ratio of cooling energy supplied to the amount of electrical energy used. It varies according to: System type and design, for example, refrigerant gas and compressor type.
