The sensors are connected with the PLC through signals.

Working principle of air conditioner

The air (return air) in the room enters the mixing chamber 3 after passing through the air coarse filter 6, and comes from the fresh air outside at the same time, according to the magnitude of the new air flow set value, the motor is controlled to enable the baffle plate 10 to move to a proper position, the new air with the set flow enters the mixing chamber 3 after passing through the air coarse filter two 9, the baffle plate 10 and the diffuser pipe 8, and is mixed with the return air from the room, the mixed air is sterilized by the ultraviolet lamp tube 12, the peculiar smell is removed after the adsorption of the active carbon in the coarse filter net cage 13, and then the mixed air with the high temperature in the evaporator 15 and the low-temperature refrigerant water in the evaporator 15 perform heat exchange after passing through the air fine filter 14.

After heat exchange, the mixed air is changed into low-temperature mixed air after releasing heat, the refrigerant water is changed into high-temperature refrigerant water after absorbing heat, the low-temperature mixed air passes through the heater 16 and the humidifier 17, is accelerated by the fan 18, and is discharged into a room after passing through the mixed air outlet 19 of the air conditioner, so that the obtained sterilized, odorless, clean and low-temperature mixed air is discharged into the room, and the indoor temperature is reduced.

In the evaporator 15, when heat is exchanged, after the mixed air with high temperature contacts the evaporator 15 with low temperature, water in the mixed air can be separated out to form liquid drops, then condensed water is formed after slow gathering, the condensed water can be gathered in the condensed water collecting tank 20 under the action of gravity, and then the condensed water is introduced into the sewer 22 through the drain pipe 21.

Refrigerant water from the central air-conditioning system enters the evaporator 15 through the water inlet pipeline 23 and the first stop valve 25, is changed into high-temperature refrigerant water after heat exchange with high-temperature mixed air in the evaporator 15, and flows back to the central air-conditioning system after passing through the second stop valve 26, the water outlet pipeline 24 and the electric three-way valve 27.

Under the flow rate of the refrigerant water controlled by the PLC, a part of refrigerant water with high temperature flows back to the water inlet pipeline 23 again before passing through the electric three-way valve 27, and is mixed with the refrigerant water at the water inlet pipeline 23 again, so that the temperature of the original refrigerant water is slightly increased, the refrigerant water with slightly increased temperature enters the evaporator 15 through the first stop valve 25, and after heat exchange, the refrigerant water flows back to the central air conditioning system through the second stop valve 26, the water outlet pipeline 24 and the electric three-way valve 27. On one hand, the recycling of the refrigerant water can improve the utilization rate of the refrigerant water and play a role in energy conservation; on the other hand, the refrigerating water with slightly high temperature can be provided, and the indoor temperature is prevented from being too low.

In order to control the temperature in the room within a set range, the PLC compares actual values of the fresh air and return air temperatures detected by the first temperature sensor 36 and the second temperature sensor 38, then takes an average value of the actual values, compares the average value with a set value, and sends a control signal to the electric three-way valve 27 according to the temperature deviation to operate the electric three-way valve. If the measured actual average value of the temperature of the mixed air in the room is higher than the set value, the PLC sends a signal to the electric three-way valve 27 to operate the electric three-way valve in the direction of opening the large valve, so that the flow rate of the refrigerant water flowing through the evaporator 15 is increased, and otherwise, the flow rate of the refrigerant water is decreased.

When the air in the room needs to be replaced, the fan 18 is stopped, the cover plate 41 is installed at the return air inlet 5, the fan 18 is started after the cover plate 41 is installed, the fan 18 is enabled to run reversely, at the moment, the air in the room enters through the mixed air outlet 19, then enters into the fresh air pipeline 7 after passing through the humidifier 17, the heater 16, the evaporator 15, the fine air filter 14, the coarse filter net cage 13 and the diffuser pipe 8, and then is discharged to the outside through the second air coarse filter 9. At the same time, the second air coarse filter 9 is also backwashed.

Similarly, the first pressure sensor 39 and the second pressure sensor 40 transmit different detected pressure signals to the PLC, and after the PLC compares the set pressure difference with the actual pressure difference, if the set pressure difference is higher than the actual pressure difference, the PLC sends an alarm signal to notify a person that the air fine filter 14 needs to be replaced or cleaned. The alarm after the filth blockage of the air fine filter 14 can be handled in two situations, the air fine filter 14 can be directly replaced, and the back flushing can also be carried out, wherein the back flushing procedure is the same as the procedure for replacing the air in a room.
