Structural features of refrigeration compressor blocks and other fixed parts
The body is a large part of the refrigeration compressor, which mainly bears the forces and moments generated during the compression process, the inertial forces and moments generated by each moving mass, and the unbalanced forces and moments are partially transmitted to the foundation.
In the old series of refrigeration compressors, the cylinder block and the crankcase are separated. In the new series of refrigeration compressors, the two bodies are cast as a whole, which makes the whole body rigid, small deformation during work, and reduces the sealing surface.
The body is cast with suction and exhaust cavities, and the lower part is provided with a crankcase. The suction chamber is connected to the crankcase with a pipe (the old series ammonia refrigeration compressor is connected to the external pipe). There is an oil surface mirror on the side of the crankcase, and products above the 100 series also have an oil cooler. Two bearing seat holes are opened at both ends for installing the front and rear covers and bearings.

Ultra-low temperature air source heat pump: a disruptive technology to change the way urban heating
With the acceleration of urbanization and people's increasing concern about environmental protection, traditional urban heating methods are facing severe challenges. The traditional heating mode represented by coal-fired boiler not only has the problem of pollution, but also causes the waste of energy. However, ultra-low temperature air source heat pump as a disruptive technology, is gradually changing the face of urban heating.
With the global energy crisis and the increasing awareness of environmental protection, green energy technology is rapidly rising, and heat pump technology has attracted much attention because of its high efficiency and environmental protection. As a kind of heat pump technology, air source heat pump is becoming more and more popular in domestic and foreign markets.

Air conditioning and refrigeration room and refrigeration, refrigeration room location is different, so the noise of the unit operation, vibration and other technical performance requirements are different. Air conditioning is used in two aspects: one is the comfort air conditioning in life; the other is the industrial air conditioning in industrial production, scientific research and experiment. In terms of comfort air conditioning in life, the most common are various high-level civil buildings and high-rise buildings.
The main machines and equipment of the refrigeration unit are installed in a specific machine room on site. Connect the liquid supply, return pipeline and the cooling equipment of each warehouse, which is called centralized cooling mode. At present, China's cold storage are generally used in this way of cooling.
