What is the difference between high and low temperature damp heat test box and high and low temperature test box?
The difference between high and low temperature damp heat test box and high and low temperature test box:
The shell structure is also different. The high and low temperature test environment test box will be equipped with a parts cabinet water storage tank. The high and low temperature test chamber has no water storage tank,
With the fierce market competition in the sales market, a large number of customers understand the necessity of environmental test chambers. To better promote brand awareness, environmental test chambers have long been used in electronic devices, electronic devices, circuit boards, communications, LEDs and other fields. Lack of testing equipment.
Environmental protection and energy-saving operation of high and low temperature test equipment:
Therefore, manipulating to reduce the energy consumption of high and low temperature air conditioning system software is a major part of reducing cost and energy consumption.
Carrying out environmental protection and energy-saving thinking and design schemes for high and low temperature air conditioning system software is the main problem that professional and technical personnel of today’s wide engineering projects must deal with. The high and low temperature test management center air-conditioning unit is different from other air-conditioning units because it has unique regulations on the temperature and environmental humidity in the room. Some temperature swings are indeterminate and restricted within 1°C, that is, they fluctuate around 0.5°C, and there are also higher requirements for environmental humidity.
Temperature and environmental humidity are not only controlled by external and internal standards but temperature and environmental humidity can also harm each other.
For example, when the temperature is 20°C when the temperature fluctuates by one°C, it will cause the air humidity to fluctuate by about 4%. Following the rapid improvement of mechanical processing and manufacturing technology, the fluctuation of the specified temperature and environmental humidity has been reduced. This has put forward higher regulations for the high and low temperature air conditioning system software, which will also greatly increase the consumption of air conditioning units. can.
To better reduce energy consumption, it is necessary to develop environmentally friendly design schemes for the high and low temperature air conditioning system software, and use high and low temperature test chambers to carry out tests. In addition, because the high and low temperature air conditioning system software methods mostly use traditional generator sets , Very few applications of today’s high-efficiency variable refrigerant total flow centralized air-conditioning system software. If a multi-piece split air conditioner with a variable refrigerant flow rate is used, the cold and heat source cost of the high and low temperature air conditioner can also be reduced, which is environmentally friendly and energy-saving.
Regarding the selected all-air system, the gas treatment has a scene where the cold and the heat are offset, which leads to a large increase in operating energy. Nowadays, the high and low temperature air conditioning system software has a unique place with other air conditioning units. It is to design a plan and build a high-precision high and low greenhouse, usually all air systems are used.
The temperature control knob can not be pulled out randomly:
The temperature control power switch of the refrigeration unit of the high and low temperature test laboratory is a heating type relay power switch. The temperature sensor tube for pumping air is close to the entrance and exit of the air conditioner evaporator. When the surface temperature of the air conditioning evaporator of the refrigeration unit of the high and low temperature test laboratory changes At the time, the working pressure of the vapor in the temperature sensor tube will also change, which will control the starting and stopping of the refrigeration compressor; under all normal starting and operating conditions, the working pressure of the bottom pressure end and the high-pressure end of the refrigeration compressor The foundation tends to be balanced, and the pressure difference is small. If the temperature control knob is randomly turned to the lowest temperature in the application, the refrigeration compressor will stop and open frequently, and the start will continue.
