High and low temperature test chamber refrigeration system

Low temperature test chamber temperature and humidity sensor: platinum resistance PT100Ω/MV

Heating system: fully independent system, nickel-chromium alloy electric heating heater

Refrigeration system: French original "Taikang" fully enclosed air-cooled single-stage / multi-stage compressor refrigeration

Circulatory system: temperature-resistant low-noise air-conditioning motor. Multi-leaf centrifugal wind wheel

The design of the high and low temperature test chamber refrigeration system should have energy regulation technology, which can ensure the effective adjustment of the energy consumption and cooling capacity of the refrigeration system under the normal operation of the refrigerant unit, so that the refrigeration system Operating costs and failure rates have fallen to a more economical state. In order to ensure the cooling rate and the minimum temperature requirement of the equipment, the connecting container is an evaporating condenser, and the evaporating condenser uses the low-pressure circulating evaporator as a high-pressure circulating condenser.

In addition to the main compressor, the high and low temperature test chamber refrigeration system has imported refrigeration components such as air-cooled coil condensers and fin-type multi-stage evaporators. The refrigerant is R502 (low pressure cycle).
