摘　　要：对中央空调系统的两种控制方式——压差变流量控制和温差变流量控制的原理和存在问题进行分析。考虑土壤源热泵水系统的特点,说明土壤源热泵两个水系统控制适合采用温差控制。通过一个工程实例说明土壤源热泵VWV(variable water volume)控制的设计过程。Analyzes the principle and questions of pressure difference control and temperature difference control of two control modes in central air-conditioning system. Temperature difference control adapts to the control of two water systems of ground source heat pump, considering the character of water systems of ground source heat pump. Discusses the design of variable water volume control of ground source heat pump through an engineering example.

关 键 词：土壤源热泵 VWV 温差控制
