Because the building that the energy consumption is very high needs to provide the radiant energy of super high temperature and super low temperature to guarantee the humiture of indoor environment, such high radiation has surpassed the comfort that people can accept, and the reaction that also very big stimulation people's health arouses and causes unhealthy.

The existing variable frequency air conditioner solves the problem of energy consumption caused by frequent starting of an outdoor fixed frequency machine due to the fact that the indoor temperature of the fixed frequency machine is greatly changed. The working principle of the frequency converter is that after the indoor temperature requirement is met, the frequency converter is changed into energy-saving low-frequency operation, and even under the low-frequency operation, the frequency converter has energy consumption. At present, the most economical lowest frequency operation frequency is about 30RHz, the frequencies of air conditioners of different brands are different, the air conditioners operate under low frequency, the energy consumption caused by 1P of variable frequency air conditioners is about 200W/h, and the energy consumption of variable frequency air conditioners of other models is higher.
For buildings with near zero energy consumption and ultra-low energy consumption, the refrigeration energy consumption of a single square meter building is about 10W-20W, because the indoor environment heat preservation performance and the air tightness are excellent, and fresh air heat exchange is adopted, the temperature difference of 4 ℃ in the personnel density range of the building design standard can be kept for 3 to 4 hours and cannot exceed the set temperature and the error range. Therefore, it is most energy-saving that the outdoor unit is stopped after the indoor temperature reaches the set temperature threshold.
For a special full-quality air conditioner with near zero energy consumption and ultra-low energy consumption, namely a fresh air conditioner all-in-one machine and an environmental energy all-in-one machine), the operation modes of the all-in-one machine are a refrigeration mode and a heating mode. Dehumidification mode, new trend mode, each mode can be according to outdoor temperature detection automatic setting, also can artificial manual setting. After setting, in order to maintain the indoor environment constant temperature, constant humidity, constant oxygen, constant cleanness and constant silence, after parameters are manually set, the system generally runs under the automatic condition, the running logic of the original outdoor frequency converter is continued, the logic and the program of shutdown are not increased, thereby causing unnecessary energy waste and influencing the service life of the compressor and other accessories.
