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

Abstract

The invention discloses a constant-temperature and constant-humidity air conditioner system with ultrahigh precision and a control method. The constant-temperature and constant-humidity air conditioner system comprises an indoor unit and an outdoor unit module, wherein the indoor unit comprises a case as well as a mixing chamber, a filtering chamber, a humidifying chamber, a temperature-adjustingheating chamber and an air outlet section which are formed in the case; the humidifying chamber is located between the filtering chamber and the temperature-adjusting heating chamber; the outdoor unitmodule comprises an outdoor unit, a defrosting unit matched with the outdoor unit and a constant-temperature water humidification unit for executing humidification operation on the humidifying chamber. Indoor air is subjected to humidity adjustment by means of constant-temperature water provided by the outdoor unit, heat-humidity exchange is performed in the humidifying section to control absolute humidity of air output by the unit, and humidity precision of the air conditioner unit is guaranteed by controlling the absolute moisture content of the air output by the unit; temperature of outletair of the indoor unit is controlled separately by the temperature-adjusting heating chamber, so that independent control over temperature and humidity of the outlet air is realized, and control overthe temperature and the humidity of the outlet air is more accurate.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an ultra-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 September 4, 2002. At the meeting, the International Institute of Refrigeration published "The Commitm...

Problems solved by technology

[0005] However, the existing constant temperature and humidity air conditioning units only operate in the compression refrigeration mode, which does not save energy. At the same time, the precision of the temperature and humidity controlled is low, and it is difficult to achieve precise control of the temperature and humidity of the air conditioner.
