Heating system combined with air source heat pump and gas furnace, and heating method

Abstract

The invention provides a heating system combined with an air source heat pump and a gas furnace, and a heating method thereof. The system comprises the air source heat pump, the gas furnace, a water replenishing pump, a hot water supply pump and a control device. The air source heat pump is used as a main heating source, and the gas furnace is used as an auxiliary heating source. When the hot water produced by the air source heat pump can meet the water demand, the gas furnace is in sleeping mode; and when the temperature of the hot water produced by the air source heat pump fails to reach the required temperature, the gas furnace can be ignited automatically, and the required water temperature is reached. Through the above system and the method provided by the invention, all hot water subsystems can be combined organically, and subjected to coordinated control, so that the optimization of energy consumption is achieved, and the operating state of the heating system can be controlled anytime and anywhere through local and remote monitoring functions. At the same time, the hot water control mode is improved, so that the heating system can respond to water-use environments in time, and the water demand is met.

Description

technical field [0001] The invention relates to a thermal energy application field, in particular to a combined heating system and method of an air energy heat pump and a gas furnace. Background technique [0002] At present, general commercial (or domestic) hot water systems include air energy hot water systems, solar hot water systems, electric hot water systems, gas hot water systems, etc. , sauna, foot bathing and other places), a large single hot water supply system due to climate temperature changes, equipment failures, changes in the amount of hot water caused by the uncertainty of the number of hot water users, etc. The required temperature cannot be reached, and the problem of temporary insufficient hot water supply will plague us from time to time. [0003] In order to solve this problem, the present invention proposes a technology that uses an air energy heat pump as the main heating source and a gas furnace (including: pipeline natural gas, pipeline gas, bottled...
