We know that the artificial environment refers to the use of artificial methods of low temperature cold water machine price people reach the environmental conditions of hope, but also includes a variety of climate change on the ground, air and other special requirements and the universe. Next, we reveal the contents of the experimental conditions to improve the cooling mechanism of the cold water chiller with different low temperature dual head refrigeration systems.
     We need to know which artificial environment tests require low temperature conditions. After analysis, the artificial environment test related to refrigeration can be summarized as follows:
     1, low temperature environment test: it includes the product in the low temperature environment - performance test, temperature shock test (product to withstand the low temperature cycle ability), etc..
     2, damp heat test: study or test the temperature and humidity on the product performance.
     3, salt spray test: the product is placed in a high humidity salt spray environment test, to test the products and components of the corrosion resistance.
     4, a variety of climate tests: including temperature, wind speed, rain, snow, sand test, also known as all-weather test.
     5, space simulation test: Simulation of the aircraft into the air, the environment is characterized by low temperature  and vacuum
     For the artificial environment test, the method of obtaining low temperature can be the following:
     1, the use of refrigerant: in the requirements of fast cooling, the use of a short time, you can use the refrigerant, such as liquid nitrogen, dry ice, etc..
     2, multistage refrigeration: can use a single refrigerant for the two stage or multi-stage compression, level two or multi-level throttling, in order to achieve the purpose of low temperature.
     3. Cascade refrigeration: a cascade refrigeration system with two or more different refrigerants. For example, in the cascade vapor compression refrigeration cycle, the low temperature evaporation of high temperature refrigerant is used to condense the high pressure vapor of the low temperature refrigerant.
    4, gas refrigeration: the use of compressed gas to promote the expansion of the expansion of insulation, external work, so that the gas temperature is reduced, and to achieve the purpose of refrigeration. The gas refrigeration cycle can also be a multi-stage or stacked form.
    In a word, we reveal the different conditions of the cold water chiller to improve the experimental conditions.       Refrigeration temperature environment test and used various chillers for refrigeration, refrigerant now use more environmentally friendly refrigerant, throttling capillary or thermal expansion valve, can improve the accuracy and loop of life, and can work continuously for a long time.
