The main equipment of the cooling water system includes two cooling towers and three cooling water circulation pumps.

Duct is a piping system used for air transportation and distribution, usually used in air conditioning system, ventilation system, industrial exhaust system and so on. According to the shape of the cross-section can be divided into round duct, rectangular duct, flat round duct and so on, of which the round duct resistance is the smallest but the height of the largest size, the production is complex. Therefore, the application of rectangular air duct is mainly.

This paper analyzes the causes of vibration for the vibration of the various components of the pump unit. From the pump hydraulic, mechanical structure design, to the pump installation, operation, maintenance and other aspects of several proposed measures to reduce pump vibration.

Chifeng City is the first city in China where the government has led and issued a document uniformly requesting all urban areas to carry out end-to-end large-temperature difference renovation, which plays a very important role in demonstrating the realization of low-carbon heat supply. This paper introduces the cause and realization process of large temperature difference heating in Chifeng city center, and combines the local endowment of waste heat and renewable resources, under the guidance of the above requirements, the program and implementation steps of near-zero carbon heating can be developed according to local conditions.

Against the backdrop of today's global warming and increasingly stringent energy efficiency requirements, the HVAC industry is facing unprecedented challenges and opportunities. As a global provider of sustainable environment optimization solutions, Copeland is once again leading the industry to new milestones with its innovative spirit and technological prowess.

In March 2024, Copeland announced the launch of its newly developed 50HP Large Scroll compressor solution, filling the gap of the industry's large horsepower scroll compressor. The solution innovatively realizes cold capacity enhancement and can replace the application of small-cooling capacity screw compressors, which will help users in air conditioning, heating and other fields to realize the double benefit of corporate value and social value, and promote the industry to high efficiency, low carbon and green development. The debut of this new product not only marks a new level of technological progress for Copeland compressors, but also brings the industry a new option to realize the goal of environmental sustainability.
