How to structure the refrigeration unit of the cold and thermal shock test chamber

Cold and thermal shock test chamber refrigeration unit as a key system software of machinery and equipment, very important, in order to ensure the environmental test chamber cooling speed and zui low temperature regulations, cold and thermal shock test chamber to select a complete set of imported Holland fully enclosed refrigeration compressor composition of the dualized cascade air-cooled refrigeration unit
.

The cascading refrigeration unit includes a high-temperature refrigeration cycle system and an ultra-low temperature refrigeration circulation system, the connector is an evaporative condenser, and the evaporative condenser is also the effect of kinetic energy transmission, which transmits the energy in the room according to the secondary refrigeration unit and maintains
the purpose of cooling.

The design scheme of the refrigeration unit uses kinetic energy adjustment technology, which is practical and feasible processing process to ensure that under the normal operation of the refrigeration unit, the energy consumption of the refrigeration unit and the cooling capacity of the air conditioner can be reasonably adjusted, so that the operating cost and rework rate of the cold and thermal shock test chamber refrigeration unit can be reduced to a relatively economic development situation
.

Its composition is given: First, the refrigeration compressor, the key generator set for cooling, is the same as the basic principle of the compressor, and is located at the bottom of
the temperature impact environmental test chamber.

Second, the cooler, the temperature of the cold effect, that is, the large fan equipment
on the side of the refrigeration compressor.

Third, the air conditioner evaporator, reduce the temperature, in addition to the effect is to dehumidify
.

Fourth, the relief valve, the relief valve is to manipulate the refrigerant to effectively assign to the air conditioning evaporator, so that the air conditioning evaporator is in all normal cooling work attitude
.

Several major cold components, each doing its part, cooperate with each other, can be a hot and cold temperature impact environmental test chamber to give full play to the actual effect of good cooling, and then exceed the purpose of temperature impact
