Intelligent air-cooled type constant temperature and humidity air conditioner and temperature and humidity adjustment method thereof

Abstract

The invention relates to an intelligent air-cooled type constant temperature and humidity air conditioner which comprises a compressor, an air-cooled condenser, a reheating condenser, a three-way valve, an expansion valve, an electric heater, a humidifier, an air blower and an evaporator; and the expansion valve, the evaporator and the compressor communicate mutually through pipelines in order. The intelligent air-cooled type constant temperature and humidity air conditioner further comprises an intelligent control system; an outlet of the compressor communicates with an inlet of the air-cooled condenser and an inlet of the reheating condenser; two connectors of the three-way valve communicate with an outlet of the air-cooled condenser and an outlet of the reheating condenser through the pipelines respectively; the other one connector of the three-way valve communicates with an inlet of the expansion valve through the pipeline; the intelligent control system comprises a control box, and an air intake temperature sensor, an air intake humidity sensor, an air outlet temperature sensor and an air outlet humidity sensor that are electrically connected with the control box; the control box is electrically connected with the compressor, the air blower, the three-way valve, the electric heater and the humidifier; and air sequentially passes through the evaporator, the reheating condenser, the electric heater, the humidifier and the air blower and then enters a room. Automatic control is realized according to data of air intake temperature and humidity and air outlet temperature and humidity, the control precision is high, the various work requirements can be met better, and the automation degree is high.

Description

technical field [0001] This patent relates to the field of air conditioning automation, in particular to an intelligent air-cooled constant temperature and humidity air conditioner and its temperature and humidity adjustment method. Background technique [0002] At present, the existing air-cooled constant temperature and humidity air conditioners first use the evaporator to cool down and dehumidify, and then use the electric heater to adjust the heat and the humidifier to adjust the humidity, so as to provide constant temperature and humidity air to the air-conditioned rooms with special requirements on temperature and humidity. [0003] Under partial load conditions, the cooling capacity of the compressor is too large, so that the outlet air temperature after the evaporator is cooled is significantly lower than the set temperature and humidity requirements, and electric heaters are required to achieve thermal compensation to ensure constant temperature and humidity.
