Abstract

The invention provides a thermal and humid environment integrated control air-conditioning system and method based on thermal comfort evaluation. The comfort operating level and the corresponding PWV numerical range of an air conditioner are set in strict accordance with national standards, the air conditioner is made to have the humidification adjusting function, an average thermal sensation index PMV value is calculated by acquiring air temperature, relative air humidity, average radiation temperature, wind speed, metabolic rate and clothing thermal resistance and compared with a preset comfort PMV value interval, and the air supply speed, the refrigerating / heating operating state and the humidifying / dehumidifying operating state of the air conditioner are intelligently adjusted according to the comparison result, so that a target area is in a comfort state satisfying the human body, the comfort requirement of the human body is met, the thermal comfort environment of the target area is easily improved, and energy conservation and emission reduction of a building are promoted. The principle and parameter setting of the system and method are scientific, and the operation method is simple and easy to control and implement.

Description

technical field

[0001] The invention relates to the field of energy saving and environmental protection, in particular to an air conditioning system and method for comprehensively controlling heat and humidity environments based on thermal comfort evaluation. Background technique

[0002] With the development of economy and technology and the continuous improvement of living standards, people have higher and higher requirements for thermal comfort of indoor environment. It is particularly important to create a healthy, comfortable, environmentally friendly and energy-saving indoor environment. Air conditioners have become the main tool for people to create an indoor environment at present.

[0003] The existing air-conditioning comfort control method is based on the PMV model proposed by Professor Fanger of the Technical University of Denmark, using the human thermal sensation index, based on the thermal balance of the human body, and combining the subjective feelings of psy...

Examples

Embodiment Construction

[0035] The heat-humidity environment comprehensive control air-conditioning system and method based on thermal comfort evaluation provided by the present invention are mainly applied to air-conditioners with humidification and dehumidification adjustment equipment. For example, an air conditioner with the following existing humidification and dehumidification adjustment equipment: includes a condensed water receiving pan located under the evaporator of the indoor unit of the air conditioner, which is connected to the water tank of the indoor unit through a water pipe; located under the heat exchanger of the outdoor unit of the air conditioner The condensed water receiving tray, which is connected to the water tank of the outdoor unit through water pipes; the pressurized water pump connected to the water outlet pipe of the outdoor unit water tank, and the water pump is connected to the water tank of the indoor unit through a hose; the ultrasonic humidifier connected to the water ...
