Fully enclosed liquid cycle refrigeration and heating consists of many accessories, such as compressors, condensers, expansion valves, heat exchangers, temperature controllers, circulating pumps, pre-cooling units, heating units, refrigeration units, etc.
Each component has its own functions and advantages
.
The rate of most exothermic chemical reactions in fully closed liquid cycle refrigeration heating increases with increasing temperature and decreases with decreasing temperature
.
If the reaction temperature is lowered, the reaction will slow down and unreacted materials may accumulate in the reactor
.
If the reaction temperature rises again, unreacted species may start to react
.
If there is enough unreacted material, the heat released by the reaction may exceed the cooling capacity of the reactor
.
Some unimportant chemical reactions (including decomposition reactions) in medicine and chemical industry may become important reactions at high temperature, which will release more energy, and there may be gases in the reaction products, which can generate high pressure in the reactor
.
1.
Compressor: It mainly plays the role of refrigeration.
It is called the heart of the unit and is a very important key component.
A good compressor should not only operate stably, but also ensure good energy efficiency
.
2.
Evaporator: It plays the role of heat absorption.
Sufficient and suitable heat exchange can give full play to the efficiency of the compressor.
If the heat exchange of the condenser is insufficient, it will directly affect the cooling effect of the unit.
High pressure is prone to occur in summer.
3.
Condenser: The heat exchange between condenser and evaporator is more important.
Insufficient heat exchange will not only cause low efficiency of the unit, but if it is too small, the refrigerant will not be completely Evaporation will directly return to the compressor to cause liquid shock and damage the compressor, thus making the entire cooling and heating cycle unit unusable
.
4.
Expansion valve: The expansion valve is not only a flow control valve in the refrigeration system of the cold and heat cycle device, but also a throttle valve in the refrigeration equipment.
The wet vapor of the low-temperature and low-pressure refrigerant enters the evaporator, and evaporates and absorbs heat in the evaporator, so as to achieve the purpose of cooling and cooling
