Detailed description of piping of refrigeration and heating cycle equipment

When the refrigeration and heating cycle equipment is in operation, the user will find that whether or not the fully enclosed pipeline affects the overall performance. The LNEYA refrigeration and heating cycle equipment adopts a fully enclosed cycle pipeline, and there is no oil mist and water vapor during high and low temperature operation, which is continuously improved. Operational efficiency, so what is important in piping design?

The refrigeration and heating cycle equipment adopts a fully enclosed pipeline design and a high-efficiency plate heat exchanger, which reduces the demand for heat transfer fluid while increasing the heat utilization rate of the system to achieve rapid temperature rise and fall. The heat transfer medium is in a closed system with an expansion vessel. The heat transfer medium in the expansion vessel does not participate in the circulation. Whether it is high or low temperature, the temperature of the expansion tank is from room temperature to 60 degrees, which can reduce the absorption of moisture and volatilization of the heat transfer medium during operation. risk.

The refrigeration and heating cycle equipment should keep the entire system of the refrigeration and heating cycle equipment group clean after installing the compressor welding pipes to avoid welding slag and other impurities in the refrigeration and heating cycle equipment system, causing serious malfunctions during compressor operation. Vibration is unavoidable during operation. In order to reduce the vibration of the pipeline, it is recommended to use copper pipes as suction and exhaust pipes. In this way, when the compressor is running normally, the copper pipe in the pipeline can reduce the vibration. If steel pipes are to be used for the piping in the system, proper welding techniques are very important to avoid stress in the piping system. These internal stresses will cause resonance and noise, which will reduce the service life of the compressor.

After the refrigeration and heating cycle equipment is welded, the oxidized impurities and debris generated by the welding of the pipeline should be removed in time. If these impurities enter the compressor, it may cause the oil filter to block and make the lubrication system and the capacity adjustment system fail. If the suction and discharge flanges of the compressor of the refrigeration heating cycle equipment are made of cast steel, they can be directly welded to the pipeline. After welding, it should be cooled in the atmosphere, and cooling with water is prohibited.

LNEYA refrigeration and heating cycle equipment is different from other manufacturers in terms of overall performance. Different manufacturers have different prices and configurations, so you need to pay attention to the price of one product.
