Problems solved by technology

[0002] In order to realize the constant temperature control of the air-cooled modular unit, in the prior art, it is usually adjusted and controlled according to the water temperature of the cooling water. However, this method often leads to large fluctuations in the water temperature, which in turn leads to frequent changes in the entire temperature adjustment and control mode. The air-cooled modular unit Problems such as frequent start and stop; the problem of reducing the service life of the air-cooled modular unit

Abstract

The present invention relates to the technical field of air conditioning, and in particular to a constant temperature control method and system for an air-cooled modular unit. The air-cooled modular unit includes a shell-and-tube heat exchanger, a fan, and a compressor; The water end is provided with a first temperature sensor, and the first temperature sensor is used to detect the real-time water temperature. The method is: obtain the set target water temperature, real-time water temperature, and the current operating state of the compressor; calculate the target water temperature and real-time water temperature When the deviation is within the threshold range, the compressor is controlled to keep running in the current operating state; when the deviation exceeds the threshold range, the operating mode and operating time of the compressor are determined according to the range of the deviation, The compressor is controlled to continue running according to the operation mode and the operation time in the current operation state; the present invention effectively ensures that the water temperature on the use side of the air-cooled modular unit is stable and constant, and avoids the problem of frequent start and stop of the air-cooled modular unit.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a constant temperature control method and system for an air-cooled modular unit. Background technique [0002] In order to realize the constant temperature control of the air-cooled modular unit, in the prior art, it is usually adjusted and controlled according to the water temperature of the cooling water. However, this method often leads to large fluctuations in the water temperature, which in turn leads to frequent changes in the entire temperature adjustment and control mode. The air-cooled modular unit Problems such as frequent start and stop; lead to the problem of reduced service life of the air-cooled modular unit. Contents of the invention [0003] The invention provides a constant temperature control method and system of an air-cooled modular unit to solve one or more technical problems in the prior art, and at least provide a beneficial option or create cond...
