Temperature control method and device for cold radiation air conditioner system

Abstract

The invention relates to a temperature control method and device for a cold radiation air conditioner system. The method includes the following steps that a radiation heat exchange relation between the ceiling surface temperature of the cold radiation air conditioner system and the indoor human body surface area is obtained, and meanwhile a convex heat exchange relation between the indoor air temperature and the indoor human body surface area is obtained; a balance equation is established according to the heat exchange equivalence principle, the radiation heat exchange relation and the convex heat exchange relation of different types of air conditioner systems; calculation is conducted according to the balance equation, and a relation between the indoor air temperature and the ceiling surface temperature of the cold radiation air conditioner system is obtained; equivalent conversion is conducted by means of the relation between the indoor air temperature and the ceiling surface temperature of the cold radiation air conditioner system according to the preset indoor air temperature, a set value of the corresponding ceiling surface temperature is obtained, and the ceiling surface temperature of the cold radiation air conditioner system is adjusted. According to the temperature control method and device for the cold radiation air conditioner system, the problem of control over the temperature in the practical running and operation process of a cold radiation air conditioner is solved, and a good experience of a user is ensured while energy is saved.

Description

technical field [0001] The invention relates to the technical field of large-scale central air-conditioning in buildings, and more specifically relates to a temperature control method and device for a cold radiation air-conditioning system. Background technique [0002] In the field of central air conditioning, the thermal comfort of end users is usually one of the important indicators used to evaluate whether the functions of the central air conditioning system are effectively realized. The so-called thermal comfort of the human body refers to the subjective and objective evaluation of the human body's satisfaction with the hot and humid environment. Thermal comfort is the feeling of comfort obtained by the human body through thermal balance and the environmental conditions it feels. It is determined by a combination of physiology and psychology, and it focuses more on psychological feelings. It is an environmental parameter that affects the thermal comfort of the human bod...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the temperature set by the control panel of the cold radiation air conditioning system in the prior art is the surface temperature of the cold radiation ceiling instead of the indoor air temperature, which is easy to cause misunderstandings for ordinary users And missetting, resulting in poor actual use effect of cold radiation air conditioner, providing a temperature control method and device for cold radiation air conditioner system
