The invention discloses a method for calculating and controlling the heating capacity of a hybrid heat pump system. The hybrid heat pump system is composed of a heat pump unit and an auxiliary heat source unit. Based on the calculation control method, the heat pump unit and / or the auxiliary heat source unit are enabled on demand, wherein, The specific calculation and control method includes the following stages: a detection stage, a calculation stage, and a judgment stage, so that the auxiliary heat source unit can be turned on independently or the heat pump unit and the auxiliary heat source unit can be turned on at the same time.
Description
technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to a method for calculating and controlling the heating capacity of a hybrid heat pump system. Background technique [0002] Most of the existing heat pump units have the following problems when the ambient temperature is lower than a certain temperature value, and they have the following problems: 1) The energy efficiency is relatively low; 2) The compression ratio is high, which leads to an increase in the probability of unit failure and affects 3) Low energy efficiency leads to increased power consumption. [0003] However, other existing heat sources have better energy efficiency in specific situations. For example, gas furnaces are most efficient in the operating range of 60°C-80°C, and solar energy can reach 100°C under proper adjustment. Therefore, how to use other heat sources as the heat pump unit? Auxiliary heat source, operating in the most efficient and...
