Intelligent water-cooling type constant temperature and humidity air conditioner and temperature and humidity adjusting method thereof

Abstract

The invention relates to an intelligent water-cooling type constant temperature and humidity air conditioner. The intelligent water-cooling type constant temperature and humidity air conditioner comprises a compressor, a water-cooling condenser, a reheating condenser, a three-way valve, an expansion valve, an electric heater, a humidifier, an air feeder, an evaporator and an intelligent control system, and the expansion valve, the evaporator and the compressor communicate in sequence through pipelines; outlets of the compressor communicate with inlets of the water-cooling condenser and the reheating condenser correspondingly; two connectors of the three-way valve communicate with outlets of the water-cooling condenser and the reheating condenser through pipelines correspondingly, and another connector of the three-way valve communicates with an inlet of the expansion valve through a pipeline; the intelligent control system comprises a control box, an air inlet temperature sensor, an air inlet humidity sensor, an air outlet temperature sensor, an air outlet humidity sensor, wherein the air inlet temperature sensor, the air inlet humidity sensor, the air outlet temperature sensor and the air outlet humidity sensor are electrically connected with the control box; the control box is further electrically connected with the compressor, the air feeder, the three-way valve, the electric heater and the humidifier; and air passes through the evaporator, the reheating condenser, the electric heater, the humidifier and the air feeder in sequence and then enters into a room.

Description

Technical field [0001] This patent relates to the field of air-conditioning automation, in particular to an intelligent water-cooled constant temperature and humidity air conditioner and its temperature and humidity adjustment method. Background technique [0002] At present, the existing water-cooled constant temperature and humidity air conditioners first use an evaporator to cool down and dehumidify, and then use electric heaters to adjust heat and humidifiers to provide constant temperature and humidity air to air-conditioned rooms with special requirements for temperature and humidity. [0003] Under part-load conditions, the compressor’s cooling capacity is too large, so that the outlet air temperature of the evaporator after cooling is significantly lower than the requirement of the set temperature and humidity value. An electric heater is required to achieve thermal compensation to ensure the purpose of constant temperature and humidity. The working energy consumption of el...

Problems solved by technology

[0005] When the above scheme is used to cool down the air, the heat recovery device does not work; when the air is heated up, the heat recovery device is started, and the heat exchanged by the water-cooled condenser can be recovered by controlling the three-way valve, reducing or even Replace the operation of the electric heating tube, but the control method of this scheme is relatively simple, and the details of how to control it are not clear, such as which data is used for feedback and control
