水源热泵空调系统的特点及设计方法

本文从保护环境建筑节能的要求出发，重点介绍了水源热泵系统的特点、水源热泵的管路特点、水源热泵的辅助热源和水源热泵机组在设计中应注意的事项等问题。水源热泵克服了空气源热泵的缺点，并且具有其独特的特点；水源热泵空调系统的设计与施工是一项系统性工作，需要从多方面来分析这一工程的特点，本文主要介绍了水源热泵管路设计的六个特点；目前，使用的辅助热源有多种形式，本文主要介绍了电加热(即蓄热)系统；蒸汽加热系统；空气源热泵系统等三种形式，并着重介绍它们各自的优缺点。

The feature and design methods of water-source heat pump system

For the requirement of environment protection and building energy efficiency, this essay places emphasis on the feature,duct specialty,supplementary heat source of heat pump and its key points during design, the water-source heat pump system has overcome the defaults of air-source heat pump, and has Its particular feature as well. The design and construction of the water-source heat pump system is a work of series and needs analysis from all aspects.Six features about water-source heat pump system are emphasized here. There are several forms for the current supplementary heat source. This essay emphasize on three forms, which are electric heating, steam heating and air-source heat pump, and their advantages and disadvantages.
