Problems solved by technology

[0003] Due to unreasonable water temperature setting selection, it will cause indoor temperature fluctuations and unnecessary energy loss
And if it is necessary to maintain a certain degree of indoor comfort for a long time, the user needs to manually adjust the set water temperature of the two-connected heat pump unit, so that the user needs to adjust both the indoor temperature setting and the water temperature setting of the two-connected heat pump unit. This kind of control is not intelligent enough, and it increases the user's burden and reduces the user experience.

Abstract

The invention belongs to the technical field of heat pumps, and discloses a control method of a dual heat supply pump system and a water temperature control device. The control method of the dual heat supply pump system comprises the following steps: acquiring a required water temperature parameter and a detection period; calculating a room temperature change value and an indoor temperature deviation value in a detection period according to a function defined by the control method; determining relevant parameters in a target control water temperature function of the heat pump system according to the room temperature change value in the detection period and the indoor temperature deviation value in the detection period; and determining a target control water temperature function of the heat pump system, and obtaining the target control water temperature of the heat pump system in the detection period through calculation of the target control water temperature function of the heat pump system. Through the control method of the dual-combined heat supply pump system, the dual-combined heat supply pump unit and the indoor equipment control establish a linkage relation, the capacity of automatically adjusting the set water temperature according to the indoor load change is achieved, and the number of times of manually adjusting the dual-combined heat supply pump unit by a user is reduced.

Description

technical field [0001] The invention relates to the technical field of heat pumps, in particular to a control method and a water temperature control device for a two-connected heat pump system. Background technique [0002] At present, the target control of the existing two-connected heat pump units, including air source heat pump air conditioners, ground source heat pumps, water source heat pumps, etc., is only to control the start-stop and energy adjustment of the set target value. Linkage to the indoor load change of the user end. [0003] Due to unreasonable water temperature setting selection, it will cause indoor temperature fluctuations and unnecessary energy loss. And if it is necessary to maintain a certain degree of indoor comfort for a long time, the user needs to manually adjust the set water temperature of the two-connected heat pump unit, so that the user needs to adjust both the indoor temperature setting and the water temperature setting of the two-connected...
