Description

technical field

[0001] The patent of the present invention relates to an automatic capacity adjustment and control method of a building environment combined cooling and heating energy system driven by various optional clean fuels such as natural gas or biogas. More specifically, it is realized by a gas engine heat pump system. The invention relates to a capacity automatic adjustment and control method for cooling and hot water supply in summer, and heating and hot water supply in winter for year-round operation. Background technique

[0002] In recent years, many areas of our country suffer from severe power shortage in summer. According to experts' prediction, the power shortage situation in summer will not be effectively alleviated within a few years. Electric air-conditioning is the main reason for the peak load in summer. The combined cooling and heating units driven by gas engines basically do not need electric load. Facing cost, environment...
