The price difference between high and low temperature impact test chambers and high and low temperature test chambers is reflected in what aspects

High and low temperature impact test chamber and high and low temperature test chamber are environmental test equipment, high and low temperature impact test chamber is a large high-precision complex test chamber that can form high temperature, low temperature, high and low temperature difference impact inside the test chamber
.

The high and low temperature test chamber is an ordinary simple structure test chamber that can form a constant difference between high temperature, low temperature and high and low temperature inside the test chamber
.

1, the similarities and differences between the volume of the inner box: the volume of the inner box of the high and low temperature test box generally accounts for 1/3 of the whole, and the inner box of the high and low temperature impact test box is 1/8 of the size of the outer box, the high and low temperature impact test box hides 2 temperature storage boxes, and a high and low temperature impact test box is equivalent to 3 high and low temperature test boxes
.

The high temperature area of the high and low temperature impact test box is only responsible for storing high temperature energy, the low temperature zone of the high and low temperature impact test box is only responsible for storing low temperature energy, the high and low temperature impact test box test area is responsible for receiving high or low temperature energy exchange, the high and low temperature test box has only one area, and the experimental area can be changed into a high temperature or low temperature zone
through program control.

2, the similarities and differences of the test function: because the cold and heat shock is three independent zones, the exchange speed of high and low temperature energy is very fast, and the exchange of high temperature to low temperature can be completed within 2 minutes, because the exchange mode of high and low temperature impact test chamber is energy rapid neutralization, or forced neutralization
.

The high and low temperature test chamber is a zone, so the exchange of high and low temperature energy is a slow process, which is to rely on the refrigerant to take away the heat little by little or the heating system to neutralize the cold volume
little by little.

3, the similarities and differences in the body structure: mainly the refrigeration system is not the same, cold and thermal shock test box refrigeration for two-stage cascade refrigeration, so there are 2 refrigeration heads, and other auxiliary accessories used with high and low temperature test box for single-stage refrigeration, there is only one refrigeration compressor, there are many less auxiliary accessories
