Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0021] This judgment method of defrosting exit is used for such as figure 1 and figure 2 In the shown heat pump system, the system includes a heat pump unit and a wire controller. The heat pump unit is provided with an ambient temperature sensor 105 and a high pressure sensor 106 located in the high pressure section of the unit. The control method includes the following steps:

[0022] Parameter initialization setting, through the keyboard on the wired controller to set the preset minimum ambient temperature value T that should be met when the system exits the defrosting mode tcHJ , The preset minimum saturated condensing temperature value T that the refrigerant under high pressure should meet when the system exit...

Abstract

The invention provides a heat pump system and a judgment method for defrosting retreat of the heat pump system, and belongs to the technical field of air source heat pumps. The problems that in the design in the prior art, judgment is achieved only according to the environment temperature value, misjudgement is prone to happening, and consequently the defrosting time is too long are solved. According to the heat pump system and the judgment method for defrosting retreat of the heat pump system, the heat pump system comprises a heat pump unit and a wire controller, and is characterized in thatan environment temperature sensor and a high voltage sensor arranged in the unit and located on the high voltage segment are arranged in the heat pump unit; and the control method comprises the following steps of parameter initialization setting and the like. The heat pump system and the judgment method for defrosting retreat of the heat pump system have the advantages that on the basis that judgment is achieved only according to the environment temperature value in the prior art, judgment of the pressure value is added (pressure detection is more accurate, delay of the detection value is small), judgment of defrosting retreat is more accurate, the problems that, judgment is originally achieved only according to the environment temperature value, misjudgement is prone to happening, and consequently the defrosting time is too long are solved, and the use effect of users is improved.

Description

technical field [0001] The invention belongs to the technical field of air source heat pumps, and in particular relates to a heat pump system and a method for judging its defrosting exit. Background technique [0002] In the existing air source heat pump system, the judging condition when defrosting exits basically only refers to the temperature value collected by the temperature sensor, but the temperature collected by the temperature sensor may deviate due to the change of the ambient temperature or its own insulation problem, and When there is a large change in temperature, there will also be a problem of detection delay. When the detected temperature is lower than the actual value, it will prolong the defrosting exit time and affect the user's use effect (the water temperature drops during defrosting, the longer the defrosting time, the more the water temperature drops, and the more the user's use effect is affected). Contents of the invention [0003] The object of t...
