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.

Global Heat Pump Boom! Explore the reasons why air source heat pumps are popular in domestic and foreign markets!


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.

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.

The difference between the location of air conditioning refrigeration room and freezing and refrigerating machines


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.

Analysis of Advantages and Disadvantages of Centralized Cooling and Decentralized Cooling in Refrigeration System


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.
