A high-precision constant temperature and humidity air conditioning system and control method

Abstract

The invention discloses a high-precision constant-temperature and constant-humidity air conditioner system and a control method thereof. The high-precision constant-temperature and constant-humidity air conditioner system comprises an indoor unit and an outdoor air conditioner system module, wherein the indoor unit comprises a case, a mixing chamber formed in the case, a filtering chamber, a humidifying chamber, a temperature adjusting heating chamber and an air outlet section; the humidifying chamber is located between the filtering chamber and the temperature adjusting heating chamber; the outdoor air conditioner system module comprises an outdoor unit, a defrosting unit matched with the outdoor unit and a constant temperature water humidifying unit for humidifying the humidifying chamber. According to the high-precision constant-temperature and constant-humidity air conditioner system and the control method of the invention, indoor air is humidity adjusted by the constant temperature water supplied by the outdoor unit, and the heat-humidity exchange is performed in the humidifying section to control the absolute humidity of the air conditioner system; the air conditioner systemensures the humidity accuracy of the air conditioner system by controlling the absolute moisture content of the air outlet of the air conditioner system; and secondly, the air outlet temperature of the indoor unit is controlled by the temperature adjusting heating chamber separately, thereby achieving independent control of the air outlet temperature and humidity, and the control of the air outlettemperature and humidity is more accurate.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a high-precision constant temperature and humidity air conditioning system and a control method. Background technique [0002] With the increasingly prominent contradiction between economic development and energy supply, energy issues are becoming a bottleneck restricting China's completion of industrialization and urbanization development stages and the rapid development of the national economy. Energy conservation and emission reduction have become the basis for national economic security and sustainable development. national policy. [0003] Energy saving and environmental protection are two major problems that human beings need to solve urgently. The World Summit on Sustainable Development was held in Johannesburg, South Africa from August 26 to May 4, 2002. At the meeting, the International Institute of Refrigeration published "The Commitment of the Re...

Problems solved by technology

[0005] However, the existing constant temperature and humidity air conditioning system is difficult to accurately control the temperature and humidity of the air conditioner during operation.

Moreover, when the traditional constant temperature and humidity air conditioning system performs defrosting treatment, the entire air conditioning system will experience a large energy attenuation, which will affect the use effect of the air conditioning system.
