The refrigeration principle of hot and cold impact test box
Hot and cold impact test cases according to the experiment requirement and test specification is divided into three van and two box, difference depends on the experimental method and the internal structure is different. Three box is divided into cold storage chamber, thermal storage room and laboratory, commodity in the test is placed in the laboratory. Two box is divided into high greenhouses and low greenhouses, is based on motor drive basket fitness movement to complete the transformation of high and low temperature test, goods in the basket, with the blue to move together. Hot and cold impact test chamber refrigeration cycle with inverse KaRe circulation system, the circulatory system consists of two isothermal processes and two adiabatic process. The whole process of the following: refrigerant compressor insulation shrunk to a higher working pressure and took work make the exhaust temperature rises, cold media after the cooler isothermally and material around the heat exchanger, the heat is sent to all round material. Refrigerant through the valve, work is adiabatic deformation refrigerant temperature decrease at this moment. After cold media according to the air conditioning evaporator from higher temperature isothermal objects endothermic reaction, reduce temperature by cooling objects. The circulatory system cycle to achieve the purpose of cooling. In order to ensure the hot and cold impact test chamber cooling speed and low temperature regulation, this environmental test chamber to choose a semi-closed refrigeration compressor of binary cascade water cooling refrigeration unit ( Need to install every hour in the outdoor cooling water flow for 10 tons of closed loop system cooling tower, show by the customer) 。 Cascade refrigeration unit includes a system of high temperature thermal cycle and a low temperature refrigeration cycle system, the connecting vessel for evaporation cooler, evaporation cooler is also to the effect of kinetic energy transfer, energy according to the secondary refrigeration unit will work in the room transfer out, complete cooling purposes. Refrigeration unit adjust the technical design scheme of using kinetic energy, a kind of practical and feasible processing method can not only ensure the refrigerating units can all normal operation and under the condition of energy consumption of refrigeration units and air conditioning refrigerating capacity to carry out the reasonable adjustment, decrease the operating cost and repair rate of refrigeration unit to compare the situation of the economic development. The above explanation is the hot and cold impact test chamber, the refrigeration principle of hope can help you, if you want to learn more about information about hot and cold impact test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!
