Abstract

The invention discloses a high and low temperature shock test box and a refrigeration system thereof. The refrigeration system comprises a compressor, a heat regenerator, a condenser, an evaporator and a throttling valve. An outlet of the compressor is connected with an inlet of the condenser, an outlet of the condenser is connected with a high-pressure side inlet of the heat regenerator, a high-pressure side outlet of the heat regenerator is connected with an inlet of the throttling valve, an outlet of the throttling valve is connected with an inlet of the evaporator, an outlet of the evaporator is connected with a low-pressure side inlet of the heat regenerator, and a low-pressure side outlet of the heat regenerator is connected with an inlet of the compressor. The cost and equipment running energy consumption can be reduced, and the refrigeration temperature range of the high and low temperature shock test box can be widened.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a high and low temperature impact test chamber and a refrigeration system thereof. Background technique [0002] The environmental test chamber is a kind of equipment that simulates the natural environment climate by means of science and technology. Among them, the high and low temperature impact test chamber is mainly used to realize the adaptability test of electrical, electronic products, and its components and materials in high temperature and low temperature environments, and the impact test when the temperature changes sharply. In the prior art, the high and low temperature impact test chamber equipment mainly uses a single-stage pure refrigerant to achieve a temperature of -40°C or a two-stage cascade refrigeration to achieve a temperature of -70°C. It has the problems of high cost, complex system control, and high energy consumption. Moreover, the refr...
