Selection of electrical components for rapid temperature change test chamber

How to install and debug the electrical of the rapid temperature change test chamber? Need to refer to the following methods for power distribution, pay attention to the capacity of the power supply, do not use a single power supply for multiple equipment, so as to avoid voltage instability, affect the performance of the rapid temperature change test chamber machine, and even cause rapid temperature change test chamber failure shutdown. According to the incoming power supply wiring of the rap...

Advantages of LNEYA heat transfer oil heater

The heat transfer oil electric heater is a new type of thermal energy conversion device that uses electricity as the energy source and heat transfer oil as the heat transfer medium. It can provide circulating heat transfer oil of circulating pump to carry out repeated heating to reach the required heating temperature, to achieve the required temperature control process and high precision temperature control precision. Compared with traditional coal, diesel and gas boilers, heat transfer oil h...

Characteristics of the evaporator of LNEYA screw chiller

The amount of cooling capacity of the screw chiller is directly related to the energy consumption and operational economics of the entire unit, which is worthy of attention. Especially when designing a cold station, there is no single chiller in the general situation. This is mainly because when the screw chiller fails or is shut down for maintenance, it will not stop production. Instead, the reasonable unit should be selected according to the production situation. The number of units. When t...

Factors affecting cooling capacity during temperature control of battery test equipment

Battery Test Equipment Refrigeration System The greater the power of the battery test equipment compressor, the higher the cooling capacity. According to the size of the battery test equipment, the compressors of different types are selected. For example, the small battery test equipment is piston type, and the medium type is optional. Scroll type. When the water temperature of the battery test equipment (the evaporation temperature is different, the cooling capacity is different), the higher...

Importance of refrigerants in new energy vehicle battery test systems

If the flow rate of the refrigerant in the new energy vehicle battery test system is extremely small, the refrigerant will start to expand from the first expandable space at the rear end of the throttle valve. Most of the see-up of the rear end of the expansion valve is often due to lack of cooling. Or the expansion valve flow is not enough, too little refrigerant expansion will not use all the evaporator area, only the low temperature is formed locally in the evaporator, and some areas are r...

Description of the compressor of the high and low temperature damp heat test device

Different types of compressors for high and low temperature damp heat test devices often have an impact on price. When choosing, we should choose low-energy refrigeration compressors as much as possible. Now China is paying more and more attention to energy conservation and emission reduction, we must also make our own efforts. Doing this, and the loss of machinery is not much of a benefit to us, and the other is to choose less noise, so as not to affect our rest. High and low temperature dam...

Motor cooling system tests the effect of condensing temperature

The motor cooling system tests the condenser. Under normal conditions, the first half of the heat pipe is very hot, and its temperature has a slow and slow gradual decline in the balance of power. The heat sensitivity of the second half of the heat pipe is greatly reduced compared with the first half. It is because the refrigerant in the second half of the tube has gradually liquefied, and the condensation temperature and the supercooling temperature have been reached. When the motor cooling ...

Reasons for the decrease of heat transfer effect of vertical ultra-low temperature refrigerator

If the outer frost layer of the vertical ultra-low temperature refrigerator is too thick or excessively dusty, it can be caused because the external temperature of the evaporator is mostly lower than 0 °C, resulting in low heat transfer efficiency of the evaporator. Because the vertical ultra-low temperature refrigerator has relatively high humidity, the moisture in the air is easy to frost on the surface of the evaporator, and even freezes, which affects the heat transfer effect of the evapo...
