Problems solved by technology

The heating and hot water supply of gas-fired boilers are relatively clean and less polluting, but the utilization rate of useful energy is low, the cost is high, and it is not conducive to the seasonal peak shaving of gas
Electric heat pumps can also be used for heating and cooling, but the power load is large, which can easily cause power shortages
If the installations for cooling, heating and hot water supply are built separately, the total investment and operating costs will be higher

Abstract

The invention discloses a fuel gas heat pump system for refrigeration, heating and supplying hot water, comprising fume heat exchanger. A fuel gas heat pump system with compact structure of the invention for refrigeration, refrigeration, heating and supplying hot water, is convenient to take management and safety measures for the whole system, meanwhile, can supply hot water all year round and save energy, in winter, using air and engine, and supplying fuel gas as heat source, avoiding air frostiness on the heat exchanger surface in cold weather and improving heating ratio by raising air source temperature; load utilization ratio of the whole system has been raised by adding supplying heat combustor, and can supply hot water the whole year.

Description

technical field [0001] The invention relates to a gas heat pump system. Background technique [0002] At present, hot water boilers or steam boilers are mostly used for hot water supply and winter heating. The heating and hot water supply of gas-fired boilers are relatively clean and less polluting, but the utilization rate of useful energy is low, the cost is high, and it is not conducive to the seasonal peak shaving of gas. Electric heat pumps can also be used for heating and cooling, but the power load is large, which can easily cause power shortages. If the installations for cooling, heating and hot water supply are built separately, the total investment and operating costs will be higher. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a gas heat pump system for refrigeration, heating and hot water supply. [0004] Technical scheme of the present invention is summarized as follows:...
