对空气源热泵中央热水系统的若干技术研究

Technical studies on central hot water system based on air source heat pump

针对在新型节能技术之一的空气源热泵中央热水系统的设计中常遇到的工程实际问题,探讨在设计过程中应选择的设计原则和设计参数。尤其从节能目的出发,对系统选择重力型或者承压型的原则性、基础性问题作了重点分析,提出大型空气源热泵中央热水系统应采用重力型热水系统的观点。在此基础上,还对空气源热泵中央热水系统各组成部分的设计技术参数的计算和选用、管路设计要点等作了阐述。

Aiming to the design problems in central hot water system based on air-source heat pump, one of the new energy-saving technologies, we explore the design principles and the design parameters in the design process. Especially from the perspective of energy-saving, we analyze the selection between gravity type and pressure type and draw the conclusion that the gravity type should be adopted. On this basis, we present the calculation and selection of the design parameters of the system components and piping design features.
