Zero-refrigeration/hot failure clean-up
In order to balance electricity use and to reduce the peaks of the valleys, the quan region of the world has adopted the peak valley power price policy, and our zhengfu capital and electricity sector, guided by the construction of a conservation social ideology, has been promoting demand side management (dsm) to ease the tension between electricity construction and new uses。
Clean-up central air-conditioning installations are in the ordinary refrigeration range, mainly using liquid vapour refrigeration. (the main use of liquid vapourization is to absorb sub-heat and the liquid pressure varies from boiling point to boiling point, the lower the pressure, the lower the boiling point.) depending on the way the heat is transferred from high temperature to low temperature object, it can be classified as vapour compressed refrigeration, absorbent refrigeration。
The price differentials in the provision of central air-conditioning protection units in the caribbean are more than three times higher than in most areas, especially in the great peak valley. The extension of power storage technologies has been made more favourable with the further expansion of the range of electricity prices and the increase in the price ratio of electricity in the peak valley。
Central air-conditioning casings are plastic parts with limited pressure range and, if pressure occurs, the panel is deformed, the heating and cooling is affected, and significant damage is caused to the internal critical components。
2. Clean filters when they are not used during seasons in order to avoid dust accumulation affecting the next use: remove the power and remove the remote battery to prevent accidental damage: dry the body to keep the machine dry. Outdoor machines are placed on shields to avoid wind, sun and rain。
3. Reuse
Check if the filter is clean and confirm that it has been installed: remove the outdoor shield and remove the shield: test machine check if the operation is normal: confirm battery power。

When the central air-conditioning points are maintained, the plastic component, which is not pressured by the regulator when used, is of limited pressure, and if under pressure, the panel is deformed and affects the passage of the cold and warm air, it can damage important internal components in serious cases。
Dry bodies keep machines dry when they are not in use during the season, clean filters, avoid dust accumulation affecting the next use, remove power plugs, remove batteries and prevent accidental damage。
The outdoors are protected from wind, sun and rain。
Check whether the filter is clean upon reuse and confirm that it is installed: remove the shield of the outdoor machine and move the next mask object: test machine check for normal operation: confirm battery power。
