Indoor air temperature setting method and device of central air conditioner system

Abstract

The invention relates to an indoor air temperature setting method and device of a central air conditioner system. The setting method comprises the following steps that (1) expected felt air temperature data Tbody,set are set; (2) at the initial moment, relative humidity data RHin,act of indoor air are collected; (3) according to the collected relative humidity data RHin,act of the indoor air and the expected felt air temperature data Tbody,set, the indoor air temperature setting value Tin,set is calculated; and (4) the indoor air temperature setting value Tin,set is input into a control system of a central air conditioner tail end fan coil unit to control the opened degree of a valve of a freezing water pipe of the fan coil unit so as to adjust the indoor temperature. According to the indoor air temperature setting method and device of the central air conditioner system, the equivalent temperature calculating method is internally arranged, and the effect that the felt air temperature setting valve suitable for actual cold and cold feeling of a human body is equivalent to the indoor running temperature setting valve of a traditional air convection air conditioner is achieved, so that the air conditioner running temperature is conveniently recognized and set by a normal user, the problem that whether temperature control of the air conditioner tail end fan coil unit meets actual requirements of the user or not in the actual running and operating process is solved, and good experience of the user is ensured.

Description

technical field [0001] The invention relates to the field of large-scale central air-conditioning in buildings, and more specifically relates to a method and device for setting indoor air temperature of a central 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 environmental conditions. It is determined by the combination of physiology and psychology, and it is more focused on psychological feelings. The environmental parameters that affect the thermal comfort of the human body are mainly Th...

AI Technical Summary

Problems solved by technology

Traditional air conditioning systems usually use air convection heat exchange to remove or add indoor heat, often resulting in excessive heating or cooling of the building, which not only causes discomfort to the human body, but also wastes a lot of energy

Therefore, using a reasonable temperature setting to regulate the indoor thermal environment can avoid the waste of cold sources while satisfying the comfort of the human body. Set and control the temperature of the bulb instead of adjusting and controlling the temperature of the human body's thermal comfort, which may easily cause misunderstandings and poor operating results for ordinary users.
