Applications Overview

The current refrigeration and air-conditioning industry has become a vital force in my country’s equipment manufacturing industry and an important part of the national economy. In addition to being used in various aspects of life such as medicine, food, housing, and transportation, refrigeration and air-conditioning equipment is also widely used in defense and industrial fields such as aerospace, military technology, biomedicine, machinery, electronics, metallurgy, petrochemicals, energy and electricity, and nuclear applications.

When the air conditioner is in refrigeration operation, the low-temperature and low-pressure refrigerant gas is sucked in by the compressor and pressurized to become a high-temperature and high-pressure refrigerant gas. The high-temperature and high-pressure refrigerant gas passes through the condenser (generally the air conditioner is air-cooled, that is, the heat dissipation copper tube of the outdoor unit) and releases heat in the outdoor heat exchanger to become a medium-temperature and high-pressure liquid (the heat is taken away by the outdoor circulating air). The medium-temperature and high-pressure liquid is then capillary expanded and depressurized to become a low-temperature and low-pressure liquid. The low-temperature and low-pressure liquid refrigerant passes through the evaporator (indoor unit copper tube) to absorb heat and evaporate to become a low-temperature and low-pressure gas (the indoor air is cooled and cooled through the surface of the heat exchanger to achieve the purpose of lowering the indoor temperature). The low-temperature and low-pressure refrigerant gas is then sucked in by the compressor, and the cycle continues.
