The chiller is assembled from compressor, evaporator, condenser, and other accessories, and the compressor is the key part equivalent to the heart of the chiller. A little carelessness will directly affect the operation of the entire chiller. In addition to its own quality, the normal operation of the compressor also depends on the lubrication of the compressor oil. The refrigeration compressor oil is mainly used to lubricate the compressor cylinder, piston ring, bearing, speed-increasing gear, crank connecting rod and crankcase Lubricating system requires regular replacement of lubricant to ensure its quality. The chiller manufactured by the  chiller manufacturer  will be filled with refrigerant and lubricating oil before leaving the factory. Customers only need to connect the water system and power supply to use. However, during the operation of the unit, the lubricating oil will inevitably be contaminated and need to be replaced, so how to choose the correct compressor oil for th

The ice water and cooling work of the  screw chiller  are based on refrigerant. Without refrigerant, screw chillers have no refrigeration function. When you find that the screw chiller reduces the cooling effect of the equipment and reduces the cooling capacity, it is likely that the refrigerant is insufficient. So, what happens if the screw chiller lacks refrigerant? What is the performance of screw refrigerators lacking refrigerant? The most basic performance is: the cooling capacity is reduced, and the cooling effect is reduced. The lack of refrigerant for screw chillers also includes: Judging from the load performance of the compressor: When the compressor load of the screw chiller suddenly increases, sometimes overload protection will occur, and it is basically judged that there is no problem with the compressor or insufficient refrigerant. Due to insufficient refrigerant in the working chamber of the compressor, the compressor will automatically increase the working load by

Thermal expansion valve: The thermal expansion valve is both a flow regulating valve and a throttle valve in the refrigeration system. It is installed between the drying filter and the evaporator in the refrigeration equipment, and its temperature-sensitive package is wrapped at the outlet of the evaporator. Its main function is to make the high-pressure and normal-temperature refrigerant liquid throttle and depressurize when it flows through the thermal expansion valve, and become low-temperature and low-pressure refrigerant wet vapor (enter the evaporator, vaporize and absorb heat in the evaporator, and achieve the purpose of cooling). Our company provides an  auto water-cooled chiller . Evaporator: The evaporator is a heat exchange device that absorbs the heat of the cooling medium by evaporating the refrigerant liquid. Its function in the refrigeration system is to absorb heat (or output cooling capacity). In order to ensure that the evaporation process can be carried out stably

The refrigeration chiller consists of three interrelated systems: refrigerant circulation system, water circulation system, and electrical automatic control system. Our company provided by an  air-cooled scroll chiller . 1. Refrigerant circulation system: The liquid refrigerant in the evaporator absorbs the heat in the water and starts to evaporate. The liquid refrigerant also completely evaporates into a gaseous state and is sucked and compressed by the compressor. The gaseous refrigerant absorbs the heat through the condenser, condenses into a liquid, and passes through the thermal expansion valve ( (Or capillary) into a low-temperature and low-pressure refrigerant after throttling and enter the evaporator to complete the refrigerant circulation process. 2. The basic composition of the refrigeration system: Compressor: The compressor is the core component in the refrigeration system. Its function is to convert the input electrical energy into mechanical energy and compress

In some high-temperature environments, low-temperature chillers are required for cooling and cooling. The cooling function of the equipment is inseparable from many accessories. The cooler can enhance the cooling effect of the equipment. However, if the cooler has a leakage problem, the cooling effect of the unit will not be very good. How can we tell if a chiller has a leak? Take a look at the  Water Cooled Screw Chiller Manufacturer . 1. Due to the strict requirements of the  Water Cooled Chiller Machine  on the allowable pressure loss between each section and the inlet temperature, it also determines the particularity of the design and selection of the intercooler. If the intercooler leaks, the gas channel communicates with the cooling water channel, and the direction of its leakage depends on the pressure of the gas and the cooling water. Modular Type Air Cooled Machine 2. If the intercooler leaks, the cooling water will enter the gas side, and water will be entrained
