其中，该热泵机组的目标温度的控制方法应用于热泵机组的温度控制系统，该温度控制系统包括热泵机组、水箱及集控器；热泵机组与集控器通讯连接，控制器可以获取各室内的实际温度t1、t2、…、tn及各室内的设定温度T1、T2、…、Tn以后续控制热泵机组的目标温度，而当达到热泵机组的目标温度后，热泵机组自动停机；如此当水箱内的水温低于热泵机组的目标温度时，热泵机组通过压缩机压缩冷媒介质将水箱内的水换热以使得各室内的温度升高，从而满足室内的制热体验。Wherein, the control method of the target temperature of the heat pump unit is applied to the temperature control system of the heat pump unit, and the temperature control system includes the heat pump unit, the water tank and the centralized controller; the heat pump unit is connected with the centralized controller through communication, and the controller can obtain the The actual temperature t1, t2, ..., tn and the set temperature T1, T2, ..., Tn of each room are used to subsequently control the target temperature of the heat pump unit, and when the target temperature of the heat pump unit is reached, the heat pump unit will automatically stop; in this way, when the water tank When the water temperature in the water tank is lower than the target temperature of the heat pump unit, the heat pump unit compresses the cold medium through the compressor to exchange heat for the water in the water tank to increase the temperature in each room, thereby satisfying the indoor heating experience.

S120、根据各室内的实际温度t1、t2、…、tn及各室内的设定温度T1、T2、…、Tn一一确定各室内的目标温度差ΔT1、ΔT2、…、ΔTn。S120. Determine target temperature differences ΔT1, ΔT2, .

其中，根据各室内的设定温度T1、T2、…、Tn及目标温度差ΔT1、ΔT2、…、ΔTn确定热泵机组的目标温度，如此热泵机组的目标温度根据各室内的温度不同，确定不同的目标温度以满足各室内的温度升高的速率，实现了自适应性的调节热泵机组的目标温度，满足用户良好的制热体验；同时，热泵机组的电能消耗随着各室内的温度不同适当调节，有效减低热泵机组的电能消耗。解决了现有技术中热泵机组的目标温度恒定，当目标温度过高或过低等不合理情况时，造成室内温度升温过快或过慢，甚至一直无法达到室内设定的目标气温，造成非常差的制热体验等问题。Among them, the target temperature of the heat pump unit is determined according to the set temperature T1, T2, ..., Tn of each room and the target temperature difference ΔT1, ΔT2, ..., ΔTn, so that the target temperature of the heat pump unit is determined according to the temperature of each room. The target temperature satisfies the rate of temperature rise in each room, which realizes the adaptive adjustment of the target temperature of the heat pump unit and satisfies the user's good heating experience; at the same time, the power consumption of the heat pump unit is properly adjusted according to the temperature of each room. , effectively reducing the power consumption of the heat pump unit. It solves the problem that the target temperature of the heat pump unit in the prior art is constant. When the target temperature is too high or too low and other unreasonable situations, the indoor temperature rises too fast or too slow, and even the target temperature set in the room cannot be reached all the time, resulting in abnormal Poor heating experience and other issues.

可选的，在上述实施例提供的基础上，进一步对目标温度的确定进行细化，图2是本发明实施例提供的另一种热泵机组的温度控制方法的流程图；如图2所示，该温度控制方法包括：Optionally, on the basis of the above embodiments, the determination of the target temperature is further refined. FIG. 2 is a flow chart of another temperature control method for a heat pump unit provided by an embodiment of the present invention; as shown in FIG. 2 , the temperature control method includes:

S210、获取各室内的实际温度t1、t2、…、tn及各室内的设定温度T1、T2、…、Tn。S210. Acquire the actual temperatures t1, t2, ..., tn of each room and the set temperatures T1, T2, ..., Tn of each room.

S240、根据各室内的目标温度差ΔT1、ΔT2、…,ΔTn确定最大目标温度差。S240. Determine the maximum target temperature difference according to the target temperature differences ΔT1, ΔT2, . . . , ΔTn in each room.

S250、判断最大目标温度差是否小于预设值，若是，执行S260S250. Determine whether the maximum target temperature difference is less than a preset value, if so, execute S260

S260、调整温差过热温度修改系数为需求温差过热温度修正系数。S260. Adjust the temperature difference superheat temperature correction coefficient to the required temperature difference superheat temperature correction coefficient.

其中，温差过热温度修正系数用于表征热泵机组的目标温度与室内实际温度的温差的过热度。温差过热温度修正系数可以根据用户的需求及热泵机组的制热能力而决定。随着室内温度的升高，最大目标温度差逐渐减少，当最大目标温度差小于预设值时，将温差过热温度修正系数调整为需求温差过热温度修正系数，即可以理解的是，将温差过热温度修正系数调高，热泵机组的目标温度升高，如此保证热泵机组的目标温度与室内实际温度的过热度；当最大目标温度差大于预设值时，温差过热温度修正系数则不作调整。Wherein, the temperature difference superheat temperature correction coefficient is used to characterize the superheat degree of the temperature difference between the target temperature of the heat pump unit and the actual indoor temperature. The temperature difference superheat temperature correction coefficient can be determined according to the user's demand and the heating capacity of the heat pump unit. As the indoor temperature rises, the maximum target temperature difference gradually decreases. When the maximum target temperature difference is less than the preset value, adjust the temperature difference superheat temperature correction coefficient to the demand temperature difference superheat temperature correction coefficient, that is, it is understandable that the temperature difference overheat When the temperature correction coefficient is increased, the target temperature of the heat pump unit will rise, so as to ensure the superheat degree between the target temperature of the heat pump unit and the actual indoor temperature; when the maximum target temperature difference is greater than the preset value, the temperature difference superheat temperature correction coefficient will not be adjusted.

S270、根据设定平均温度、最大目标温度差及温差过热温度修正系数确定热泵机组的目标温度。S270. Determine the target temperature of the heat pump unit according to the set average temperature, the maximum target temperature difference, and the temperature difference superheat temperature correction coefficient.

其中，根据实际平均温度、最大目标温度差及温差过热温度修正系数确定热泵机组的目标温度，如此根据各室内不同的温度，自适应地调节目标温度大小，满足用户良好的制热体验；同时，热泵机组的电能消耗随着各室内的温度不同适当调节，有效减低热泵机组的电能消耗。Among them, the target temperature of the heat pump unit is determined according to the actual average temperature, the maximum target temperature difference, and the correction coefficient of the temperature difference overheating temperature, so that the target temperature can be adaptively adjusted according to the different temperatures in each room to meet the user's good heating experience; at the same time, The power consumption of the heat pump unit is properly adjusted according to the temperature of each room, effectively reducing the power consumption of the heat pump unit.

这里需说明的是，热泵机组的目标温度包括热泵机组的进水目标温度和/或热泵机组的出水目标温度。热泵机组的进水侧与水箱的出水侧相连，热泵机组的出水侧与水箱的回水侧相连；热泵机组通过压缩机压缩冷媒介质将水箱出水侧的水换热，换热后的水并通过热泵机组的出水侧回水到水箱内，回水到水箱内的水与室内的空气换热以使各室内的温度升高。集控器控制热泵机组进水侧的温度低于进水侧的目标温度，经过压缩机压缩冷媒后，热泵机组使得水箱内的水换热以使得各室内的温度升高；或者集控器直接控制热泵机组出水侧的温度低于出水侧的目标温度后，热泵机组使得水箱内的水换热以使得各室内的温度升高。It should be noted here that the target temperature of the heat pump unit includes a target water inlet temperature of the heat pump unit and/or a target water outlet temperature of the heat pump unit. The water inlet side of the heat pump unit is connected to the water outlet side of the water tank, and the water outlet side of the heat pump unit is connected to the return water side of the water tank; the heat pump unit compresses the cold medium through the compressor to exchange heat for the water on the water outlet side of the water tank, and the water after heat exchange passes through the The water outlet side of the heat pump unit returns to the water tank, and the water returned to the water tank exchanges heat with the indoor air to increase the temperature of each room. The central controller controls the temperature of the water inlet side of the heat pump unit to be lower than the target temperature of the water inlet side. After the compressor compresses the refrigerant, the heat pump unit makes the water in the water tank heat exchange to increase the temperature of each room; or the central controller directly After controlling the temperature of the water outlet side of the heat pump unit to be lower than the target temperature of the water outlet side, the heat pump unit exchanges heat with the water in the water tank to increase the temperature of each room.

可选的，当热泵机组的目标温度包括热泵机组的进水目标温度和热泵机组的出水目标温度时，根据实际平均温度、最大目标温度差及温差过热温度修正系数确定热泵机组的目标温度，包括：Optionally, when the target temperature of the heat pump unit includes the target water inlet temperature of the heat pump unit and the target water outlet temperature of the heat pump unit, the target temperature of the heat pump unit is determined according to the actual average temperature, the maximum target temperature difference, and the temperature difference superheat temperature correction coefficient, including :
