First, turn off the Gree central air conditioner, then find the "wind speed" button and "down" button of the air conditioner, and press and hold them at the same time to enter the air conditioner energy saving setting menu. We need Select the lower limit of the air conditioner cooling temperature in the display area of ??the air conditioner set temperature and set it.
Second, generally speaking, the reasonable lower limit of the air conditioner cooling temperature is between 16-30°C. Then select the mode button of the air conditioner to select the cooling and dehumidification modes of the air conditioner, and perform the corresponding Energy-saving settings, energy-saving settings are also required in the same heating mode.
Third, after the energy-saving mode is set properly, if we want to cancel this function, we must press the "wind speed" and "down" buttons at the same time when the air conditioner is turned off. When the air conditioner makes a beeping sound, it proves that the mode has been cancelled.

Working principle of water system
Water-cooled central air conditioning consists of four major components, compressor, condenser, throttling device, evaporator, refrigeration The refrigerant circulates through the above four major components in turn. The high-temperature and high-pressure refrigerant (refrigerant) gas coming out of the compressor flows through the condenser to cool down and reduce pressure. The condenser takes the heat to the cooling tower through the cooling water system and discharges it.
The refrigerant continues to flow through the throttling device, becoming a low-temperature and low-pressure liquid, flowing through the evaporator, absorbing heat, and then being compressed. There are chilled water circulation systems connected at both ends of the evaporator. The heat absorbed by the refrigerant reduces the temperature of the chilled water, causing the low-temperature water to flow to the user end, and then passes through the fan coil for heat exchange and blows out the cold air.
The working principle of the wind system
The fresh air transmission method adopts the displacement method, instead of the internal circulation principle of air-conditioning gas and the unhealthy practice of mixing old and new gases. The fresh outdoor air passes through the negative pressure method. It will be automatically sucked into the room. When it enters the room through the fresh air outlet installed on the window of the bedroom, hall or living room, it will automatically remove dust and filter.
At the same time, the corresponding indoor pipelines are connected to the exhaust vents in several functional rooms. The circulation system formed will take away the indoor exhaust gas and concentrate it on the exhaust vents to "exhale", and the discharged The exhaust gas is no longer recycled, and the old and new winds circulate well.
Working Principle of Coil System
The working principle of fan coil air conditioning system is to continuously circulate indoor air with the help of fan coil unit so that it can be cooled or heated through the coil , to maintain the required temperature and certain relative humidity in the room.
The cold or hot water used by the coil is supplied by a centralized cold source and heat source. At the same time, the fresh air after centralized treatment in the fresh air air conditioning machine room is sent to each air-conditioned room through special fresh air ducts to meet the hygienic requirements of the air-conditioned room.
Compared with the centralized system, the fan coil air conditioning system does not have large air ducts, only water pipes and smaller fresh air ducts. It has the advantages of easy layout and installation, small building space occupation, and good individual adjustment. It is widely used in comfort air conditioners where temperature and humidity accuracy requirements are not high, the number of rooms is large, the rooms are small, and individual control is required.
