Central air-conditioning system and method for dynamically adjusting temperature according to multi-user locations

Abstract

The invention relates to a central air-conditioning system achieving dynamic temperature regulation according to user positions. A difference split method is adopted, on the premise that efficient work of office staff is guaranteed, according to the condition of perception of all people on the temperature at different time stages in one day in a zone, all people participate in temperature regulation of working zones, different weights are given to different professions in cooperation with a profession working temperature weight unit, weighted average is carried out on profession working temperature and personnel set temperature of all people in the working zones, and the current optimal temperature is obtained through calculation; and an indoor positioning system is used for delimiting theworking zone covered by each fan coil, the position of each temperature set terminal in the corresponding working zone is obtained through calculation, when the office staff moves in different working zones, the temperature of different working zones is dynamically adjusted according to the movement condition of the office staff, and the flexibility and the adaptability of the system are improved. The invention further provides a central air-conditioning method achieving dynamic temperature regulation according to the user positions.

Description

technical field [0001] The invention relates to the field of central air conditioning, in particular to a central air conditioning system and method for dynamically adjusting temperature according to the positions of multiple users. Background technique [0002] A 2015 survey of 129 U.S. office workers found that 42 percent thought their building was too hot, while 56 percent thought it was too cold. We can now adjust our offices to any temperature we want, but we can't agree on a specific temperature. [0003] Setting the right room temperature can improve job satisfaction as well as productivity and collaboration. If the temperature is not set properly, it may lead to inefficient employees, obesity, and increased prevalence of metabolic disorders such as diabetes. [0004] In office places all over the world, people often argue about the temperature set in the office area. According to relevant data, about 2% of the working time in British offices is wasted on arguments ...

Problems solved by technology

[0008] Everyone's metabolic rate is different at different times of the day, so the perception of temperature is also different at different times of the day. The metabolic rate of women is much slower than that of men, and the suitable office temperature is 3 times higher than that of men. degrees Celsius (5.4 degrees Fahrenheit), however, the metabolic rate currently used when controlling office temperature is calculated based on a 40-year-old male weighing 70 kilograms, and therefore is not applicable in today's co-working environment

[0009] There are many office workers in each office area of ​​the public office space, and each individual in each office area has different perceptions of temperature at different times of the day. However, there is often only one office worker in each office area. The temperature regulator, after setting the temperature, the temperature in the office area is basically unchanged throughout the day, and cannot be adjusted to a certain extent with the metabolic rate of the human body, so the setting temperature is relatively rigid
