Embodiment 1

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

[0060] Step 1: Set the temperature of the room as T, and set the temperature deviation as ΔT1;

[0061] Step 2: Set the supply water temperature of the air source heat pump unit system to T1 and the return water temperature to T2 ( figure 1 Combine Step 2 and Step 1 together, there is no sequence relationship between the two);

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

[0063] When the current temperature deviation value of the room of the air source heat pump unit system is higher than the set temperature deviation value ΔT1 of the air source heat pum...

Embodiment 2

[0068] The difference between embodiment two and embodiment one is:

[0069] Specifically, such as figure 2 As shown, in one embodiment, the control method also includes the following steps:

[0070] Step 4: Determine whether the current temperature deviation value of the air source heat pump unit system room is higher than the set temperature deviation value ΔT1 of the air source heat pump unit system;

[0071] When the current temperature deviation value of the air source heat pump unit system room is higher than the air source heat pump unit system set temperature deviation value ΔT1 (if it is), continue to reduce the air source heat pump unit system set water supply temperature T1, and simultaneously reduce the air source heat pump unit The system sets the return water temperature T2, while ensuring that the air source heat pump unit system ΔT remains unchanged;

[0072] When the current temperature deviation value of the room of the air source heat pump unit system is ...

Embodiment 3

[0076] The difference between embodiment three and embodiment two is:

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

[0078] Step 5: Determine whether the current temperature in the room of the air source heat pump unit system is higher than the set temperature deviation value ΔT1 of the air source heat pump unit system when the set water supply temperature T1 of the air source heat pump unit system is lower than the set lower limit temperature;

[0079] When the current temperature of the air source heat pump unit system room is higher than the set temperature deviation value ΔT1 of the air source heat pump unit system (if it is), the opening of the end valve is adjusted, and the speed of the water pump is synchronously interlocked to reduce the circulating water volume of the system;

[0080] When the current room temperature of the air source heat pump unit system is not higher than the set temper...

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...
