Water system multi-online control method and system

Abstract

The invention discloses a water system multi-online control method and system. The method comprises the steps that the total horsepower of all started indoor units is calculated; the average temperature difference of all the started indoor units is calculated every other set time; the difference value of the average temperature difference is calculated; the set temperature corrected value is calculated; the target set water temperature is calculated; and operation of a compressor is adjusted according to the target set water temperature. The user set water temperature is corrected through the set environmental temperatures, the actual environmental temperatures and the capacity horsepower of the started indoor units, operation of the compressor is adjusted according to the target set water temperature, the cooling/heating speed is increased, the cooling/heating effect is rapidly improved, and the problem that in the prior art, the cooling/heating speed is low is solved; when the actual environmental temperatures of the indoor units do not reach the set environmental temperatures, the user set water temperature is corrected, the cooling/heating speed is increased, and the cooling/heating effect is rapidly improved; and when the actual environmental temperatures of the indoor units reach the set environmental temperatures, the user set water temperature is corrected, energy waste is avoided, energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a water system multi-connection control method and system. Background technique [0002] In the water system multi-connected unit, the set water temperature is the temperature set by the user through the water temperature controller. Each indoor unit can set the indoor temperature individually. [0003] In the process of compressor capacity adjustment, the compressor load is usually adjusted according to the temperature difference between the set water temperature and the actual water temperature. When the actual water temperature does not reach the set water temperature, the compressor load increases and the frequency rises; the actual water temperature reaches the set water temperature. After that, the compressor load decreases and the frequency drops until it stops. Since the change of water temperature is seriously lagging behind the change of room temp...

AI Technical Summary

Problems solved by technology

Since the change of water temperature is seriously lagging behind the change of room temperature, this method cannot adjust the real environment of the user in real time, which affects the speed of system adjustment, the cooling / heating speed is slow, the air conditioning effect is slow to improve and wastes energy.
