Abstract

A gas heat pump system using water as heat or cold source for supplying heat or cold and hot water is composed of compressing refrigerator driven by gas engine and using water as heat or cold source, afterheat recovering unit, and water channel controller consisting of valves, water pump, electronic expansion valve and pipeline. When the detected temp is not the temp setting, the delivered air flow of compressor and/or the intake flow of engine can be regulated.

Description

technical field [0001] The invention belongs to heat regulation equipment, more specifically a comprehensive system for heating, cooling and domestic hot water supply with a water source gas heat pump. Background technique [0002] The heat pump system driven by gas engine has developed rapidly due to its high utilization rate of primary energy, high heating temperature, and easy capacity adjustment. But in the patent application of relevant gas heat pump system at present, all is air source. At the beginning of 2002, Dalian Sanyo Company launched the first gas heat pump in China, which is an air source heat pump system for small users. In the patents applied by Japan's Mitsubishi Heavy Industries (Chinese patent application numbers: 02130144, 02130145, 02130146, 02128227), different operating conditions in summer and winter are not considered, and heating, cooling and domestic hot water are optimized for reasonable matching design. On the on...
