Problems solved by technology
However, due to the general water-cooled constant temperature and humidity air conditioner, the reheating and temperature adjustment are all completed by electric heating, and most of the compressors work under the condition of constant frequency. When the compressor is fully turned on, under partial load conditions, The cooling capacity of the compressor is too large, and the air outlet temperature of the air conditioner is significantly lower than the set temperature and humidity requirements. A large amount of electric heating is required to achieve thermal compensation and ensure constant temperature and humidity. Although this method can achieve the goal of constant temperature and humidity , but consumes a lot of energy
In addition, high-power electric heaters are prone to problems such as overheating, overcurrent, burning, and even fire during operation, and the operation is unreliable

The invention discloses a control method for a divided-flow water-cooling type thermostatic and humidistatic air conditioner. The control method comprises the steps that the opening degree for chilled water flow regulation is regulated in a stepless mode by comparing the detected actual compressor exhaust pressure, air temperature and air humidity with the preset compressor exhaust pressure, air temperature and air humidity, so that the compressor exhaust pressure is kept within a safety range; and precise thermostatic and humidistatic control is achieved by adjusting the opening degree of a three-way proportional control valve and operating conditions of a compressor, a humidifier and a forced draught blower.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to a control method for a split-flow water-cooled constant temperature and humidity air conditioner. Background technique [0002] The existing water-cooled constant temperature and humidity air conditioner uses evaporator to cool down and dehumidify, reheat and adjust temperature through electric heating, and then adjust humidity through humidifier, so as to meet the requirements of air-conditioned rooms with special temperature and humidity requirements, and provide constant temperature and humidity air treatment . However, due to the general water-cooled constant temperature and humidity air conditioner, the reheating and temperature adjustment are all completed by electric heating, and most of the compressors work under the condition of constant frequency. When the compressor is fully turned on, under partial load conditions, The cooling capacity of the compressor is too large, ...
