The first edition of "Prefabricated Design and Installation of Refrigeration and Heating Equipment Room" edited by China National Building Standards Design and Research Institute and published by China Planning Press is scheduled to be launched in 2024.

Prefabricated Design and Installation of Refrigeration and Heating Equipment Room "is a newly compiled atlas,It was jointly prepared by Tongji University, Shanghai Architectural Design and Research Institute Co., Ltd., and Shanghai Installation Engineering Group Co., Ltd.
1. In line with the concept of "green environmental protection, design leadership, and technological efficiency", in order toThe industry market is developing towards the refinement of design, the industrialization of module and component production, and the assembly of on-site construction, in order to solve the pain points of large on-site operations, serious pollution, material waste, low quality and efficiency, long construction period, and multiple safety hazards in traditional construction methods. This atlas is compiled to promote the systematic integration of national "green construction" technology and collaboration with "green manufacturing".
2. This atlas is applicable to the water system assembly of newly built, renovated, and expanded refrigeration and heating rooms using electric driven water-cooled chillers for cooling and heat exchange units for heatingDesign and installation. When the usage conditions of cold and heat source rooms such as heat pumps and energy storage are consistent with this atlas, relevant content can be referred to.This atlas is not applicable to heating boiler rooms.
3. This atlas proposes the technical points of prefabricated design and installation around the refrigeration and heating room, and emphasizes the importance of prefabricated safety in the installation technical pointsThe implementation steps of the installation list the common combination forms of modules in the computer room. besides,For the convenience of designers, various functions have been categorized and compiled in the drawing setModules, modular computer rooms, modular construction and installation of computer rooms, typical design of computer roomsExamples and appendices, etc. 

 The main functional modules in the image setsimpleTo explain

1Chiller unit installation module: It consists of a chiller unit and a connecting module, and this type of module has no limit on the cooling capacity range of the chiller unit. 

 2. Chiller unit+water pump module: It consists of a chiller unit, a chilled water pump, and a cooling systemPump, pump base, pipeline, valve componentsTheFilters and drainage pipesTheyesA module that integrates interfaces, pressure gauges, thermometers, flow switches, and other components. Due to the overall transportation and installation on the same frame, its external dimensions are relatively large, making it suitable for systems with small cooling capacity. When using it, it is necessary to plan the transportation and machine transportation
Room installation conditions.
   3. Pump module: adopting electromechanical integration design, with built-in control system，built-inThe performance parameters of the water pump can be optimized for energy-saving control. Except for the lifting pump moduleOutside the block, it mainly consists of a circulating water pump, a water pump vibration reduction base, and a limiterTheThe ConduitTheValve components, filtersTheModule framework, drainage pipeTheDocking interface, pressure gauge and other groupsCheng.
4. Heat exchange unit module: It consists of heat exchanger, water pump, pipeline, valve, filterConstant pressure device, instrumentTheComposed of electrical control cabinet, base, etc.
5. Takeover module: It is tailor-made for chiller units and includes pipes, valve components, pipe fittings, drainage pipes, pressure gauges, thermometers, flow switches, etcInterface docking, etc.
