Embodiment 1

[0037] Such as figure 1 As shown, an embodiment of the present invention provides a control method for a water chiller in an air conditioning system, including the following steps:

[0038] S100, detecting the temperature difference between the ambient temperature and the temperature set by the user;

[0039] S200, judging whether the detection result is less than a preset threshold;

[0040] S210, if it is judged that the detection result is less than the preset threshold, control the chiller of the air conditioning system to enter the comfort cooling mode for cooling, and control the external unit of the chiller of the air conditioning system to supply medium temperature water of 15-20°C to the internal unit of the chiller of the air conditioning system, maintain the ambient temperature in the room;

[0041] S220, if it is judged that the detection result is not less than the preset threshold, control the chiller of the air conditioning system to enter the fast cooling mod...

Embodiment approach

[0046] As an implementable manner, if the result of the judgment and detection is not less than the preset threshold, then controlling the chiller of the air conditioning system to enter the fast cooling mode for cooling includes the following steps:

[0047] S221, judging whether the water chiller of the air conditioning system has entered the fast cooling mode for a preset time or whether the temperature difference between the ambient temperature and the user-set temperature is smaller than the preset temperature difference;

[0048] If the water chiller of the air conditioning system enters the fast cooling mode for a preset time or the temperature difference between the ambient temperature and the temperature set by the user is less than the preset temperature difference, the water chiller of the air conditioning system enters the comfortable cooling mode;

[0049] Otherwise, loop detection is returned.

[0050] The outdoor unit supplies low-temperature water of 7-12°C to ...

Embodiment 2

[0056] Based on the same inventive concept, the present invention also provides a control system for the water chiller of the air-conditioning system. Since the problem-solving principle of this system is similar to the control method of the water chiller of the air-conditioning system, the implementation of the system can refer to the above-mentioned method. implementation, the repetition will not be repeated.

[0057] Such as figure 2 As shown, the control system of the chiller unit of the air conditioning system provided by the embodiment of the present invention includes a detection module 100 and a judgment module 200, wherein:

[0058] The detection module 100 is used to detect the temperature difference between the ambient temperature and the temperature set by the user;

[0059] The judging module 200 is used to judge whether the detection result is less than a preset threshold;

[0060] The judging module includes a comfort refrigeration unit 210 and a rapid refrig...

Abstract

The invention provides a control method and system of an air conditioner system water chilling unit and an air conditioner. The method comprises the following steps of detecting the temperature difference between the environment temperature and the user set temperature, and judging whether the detection result is smaller than the preset threshold value or not; if it is judged that the detection result is smaller than the preset threshold value, controlling the air conditioner system water chilling unit to enter in the comfort chilling mode to carry out chilling, controlling an outdoor unit of the air conditioner system water chilling unit to supply intermediate-temperature water of 15 DEG C to 20 DEG C to an indoor unit of the air conditioner system water chilling unit, and maintaining the indoor environment temperature; and if it is judged that the detection result is large than or equal to the preset threshold value, controlling the air conditioner system water chilling unit to enter in the rapid chilling mode to carry out chilling, controlling the outdoor unit of the air conditioner system water chilling unit to supply low-temperature water of 7 DEG C to 12 DEG C to a fan coil of the air conditioner system water chilling unit, and reducing the indoor environment temperature. According to the method, the rapid chilling requirement of the air conditioner system water chilling unit can be met, and use comfort of a user is ensured.

Description

technical field [0001] The invention relates to the field of air-conditioning and refrigeration, in particular to a control method and system for chillers of an air-conditioning system and an air conditioner. Background technique [0002] General refrigeration is to exchange heat on the evaporator of the air conditioner, and then use a fan to increase air convection and send the cold air to every corner of the room. The advantage is that the cooling speed is fast, but there are large and uneven airflows, loud noises, and comfort. Bad sex. Contents of the invention [0003] Aiming at the problems of high noise and poor comfort in general air-conditioning refrigeration, the present invention provides a control method and system for chillers of an air-conditioning system and an air conditioner that can not only cool quickly, but also meet user comfort requirements. [0004] In order to achieve the technical purpose, the embodiment of the present invention adopts the followin...
