Abstract

The invention provides a water outlet set temperature control method and a system of an air conditioning system, wherein the method comprises the steps of: obtaining a detected outdoor environment temperature value and an upper limit value and a lower limit value of set environment temperature set by users, judging and comparing if the outdoor environment temperature value is greater than or equal to the upper limit value of the set environment temperature or smaller than or equal to the lower limit value of the set environment temperature, and controlling the water outlet set temperature according to the judging and comparing result. The method can associate the water outlet set temperature with the outdoor environment temperature, and the water outlet set temperature is changed along with the change of the outdoor environment temperature, so that an air conditioning unit can satisfy the user requirements on the water outlet set temperature under various environment temperature conditions, the over-range operation of the air conditioning unit is prevented, and the use comfort and the reliability of the air conditioning unit are improved.

Description

technical field

[0001] The invention relates to the field of air-conditioning control systems, in particular to a method and system for controlling the set temperature of outlet water in an air-conditioning system. Background technique

[0002] For air-conditioning hot and cold water units, the outlet water temperature is often the user's concern. Different users have different requirements for the setting range of the outlet water temperature. Generally, the outlet water temperature setting value of the air-conditioning unit is a fixed range controlled by the manufacturer. Refrigeration, In the heating mode, there is a fixed set temperature range respectively.

[0003] However, this control method is unreasonable to some extent, because the cooling or heating capacity of the unit will be different under different outdoor ambient temperatures. If they are all controlled according to the same set temperature range, there may be The unit cannot meet the user's set water outle...
