Problems solved by technology
[0003] However, this control method belongs to post-control, and it is not suitable for occasions where there are compressors and refrigerant pumps at the same time and both need to be controlled, because in this case the unit needs to use process control.
[0004] Since the air-conditioning unit in the prior art cannot achieve technical problems such as energy-saving control, low unit operating efficiency, and high energy consumption when there are compressors and refrigerant pumps, the present invention researches and designs a control device and control method for the air-conditioning unit and air conditioning units

Embodiment Construction
[0085] Such as figure 1 As shown, the present invention provides a control device for an air-conditioning unit, wherein the air-conditioning unit includes a compressor module and a refrigerant pump module, and the control device includes:
[0086] The detection unit is used to detect the range interval of the initial ambient temperature of the unit, or to detect the respective running time of the compressor module and the refrigerant pump module in the same cycle;
[0087] The judging unit is used to calculate the respective energy efficiency ratios of the compressor module and the refrigerant pump module at the temperature (energy efficiency ratio=expected cooling capacity / unit output power), and compare the energy efficiency ratio of the two; or, compare the compressor module and the The amount of running time between refrigerant pump modules;
[0088] The execution unit selects a module with a relatively high energy efficiency ratio to start the unit, or selects a module w...

The invention provides an air conditioning unit control device, a control method and an air conditioning unit. The air conditioning unit comprises a compressor module and a refrigerant pump module. The control device comprises a detection unit, a judging unit and an executing unit, wherein the detection unit is used for detecting the range zone of the initial environmental temperature of the unit or detecting the respective running time of the compressor module and the refrigerant pump module in the same period; the judging unit is used for calculating the respective energy-efficiency ratios of the compressor module and the refrigerant pump module at the temperature and comparing the two energy-efficiency ratios, or comparing the running time of the compressor module and the refrigerant pump module; and the executing unit starts the unit by choosing the module with relatively higher energy-efficiency ratio or starts the unit by choosing the module with the shorter running time. Through the control device and the control method, the respective energy-efficiency ratios or running time of the compressor module and the refrigerant pump module can be obtained through detection and judgment, the module with the large energy-efficiency ratio or the short running time is chosen to be started, and the purposes of energy saving control and energy consumption reduction can be effectively achieved.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioning unit control device, a control method and the air conditioning unit. Background technique [0002] In the prior art, CN104613598A energy-saving monitoring method and device for air conditioning discloses a method for detecting the temperature and humidity parameters of the air in a preset area. By comparing the temperature and humidity of the supply air with the temperature and humidity of the return air, the current working status of the air conditioner is determined and analyzed. Is there any unreasonable phenomenon in the air conditioner. [0003] However, this control method belongs to post-control, and it is not suitable for occasions where there are compressors and refrigerant pumps at the same time and both of them need to be controlled, because in this case, the unit needs to adopt in-process control. [0004] Since the air-condit...
