Example Embodiment

[0058] Example one

[0059] Such as figure 1 As shown, the present invention provides a control method of an air source heat pump unit system. The air source heat pump unit system air source heat pump unit system is used to adjust the temperature of the room, and the air source heat pump unit system control method includes the following steps:

[0060] Step 1: Set the temperature of the room to T and the temperature deviation value is set to ΔT1;

[0061] Step 2: Set the water supply temperature of the air source heat pump unit system air source heat pump unit system to T1, the return temperature is set to T2 ( figure 1 The second and steps will be together in the second step, and the two have no order relationships);

[0062] Step 3: Determine whether the current temperature deviation value of the air source heat pump unit system is higher than the set temperature deviation value ΔT1;

[0063] When the current temperature deviation value of the air source heat pump unit system is...

Example Embodiment

[0076] The difference between the third embodiment and the second embodiment is:

[0077] Specifically, such as image 3 As shown in one embodiment, the control method also includes the following steps:

[0078] Step 5: Determining whether the air source heat pump unit system sets the water supply temperature T1 below the set lower limit temperature, whether the current temperature of the air source heat pump unit system is higher than the air source heat pump unit system set temperature deviation value ΔT1;

[0079] When the current temperature of the air source heat pump unit system is higher than that the air source heat pump unit system sets the temperature deviation value Δt1 (if yes), the end valve opening degree is adjusted, and the synchronous interlock adjusts the pump speed to reduce the amount of system cycle water;

[0080] When the current temperature of the air source heat pump unit system is not higher than the air source heat pump unit system sets the temperature de...

Abstract

The invention provides a control method of an air source heat pump unit system and the air source heat pump unit system. The control method comprises the steps that the temperature of a room is set to be T, and the temperature deviation value is set to be delta T1; the water supply temperature of the air source heat pump unit system is set to be T1, and the water return temperature of the air source heat pump unit system is set to be T2; whether the current temperature deviation value of the room is higher than a set temperature deviation value delta T1 or not is judged; and when the current temperature deviation value of the room is higher than the set temperature deviation value delta T1, the set water supply temperature T1 is reduced, and meanwhile it is ensured that delta T is not changed. Based on the technical scheme, by adjusting the operation state of the air source heat pump unit system, the actual water supply temperature of the air source heat pump unit system is reduced, the temperature difference between supply water and return water of the air source heat pump unit system is kept unchanged, in this way, the operation energy consumption of the air source heat pump unit system is reduced, and therefore the operation efficiency of the system is improved; and therefore, the comfort of the room is improved, and better experience is brought to the user.

Description

technical field [0001] The invention relates to the technical field of heat pump unit equipment, in particular to a control method for an air source heat pump unit system and the air source heat pump unit system. Background technique [0002] At present, in the energy consumption distribution of buildings, heating energy consumption accounts for a large proportion, which involves the rational utilization of resources. To reduce environmental pollution, the utilization rate of renewable energy, such as air energy, must be increased. Using air energy to achieve heating and cooling purposes to improve the indoor environment is a clean form of energy utilization. The air source heat pump unit system has a wide range of applications. However, in actual engineering projects, the unit selection is generally based on the maximum heat load of the design working condition, and the energy efficiency of the unit is low at this time. When the outdoor temperature condition improves and...
