The working principle of an air conditioning system in the multi-split air-conditioning floor heating system is the same as that of a common air conditioner, and the refrigeration cycle of the air conditioner is executed by using a compressor, a condenser, an expansion valve and an evaporator. Wherein the refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged. The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant.
The outdoor unit in the multi-split air-conditioning floor heating system includes a compressor and a part of an outdoor heat exchanger, the indoor unit includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit. The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
In order to realize the parallel arrangement of the floor heating system and the indoor unit, as shown in fig. 2, the floor heating water module is arranged in the outdoor unit and comprises a water pump, a sleeve heat exchanger, a water module electronic expansion valve and a water module temperature sensor, wherein the structure schematic diagram of the outdoor unit is shown in the application. The water module electronic expansion valve controls the outdoor unit to enable refrigerant to enter the sleeve heat exchanger to exchange heat with water in the floor heating water module, the water pump serves as a power source and is used for providing power for water circulation, and the water module temperature sensor monitors the temperature of circulating water in the floor heating water module so as to facilitate subsequent temperature regulation and control.
Simultaneously this application indoor set and floor heating coil correspond the setting, all be equipped with indoor set and floor heating coil in each room equivalently, and floor heating coil and indoor set in the same room can be controlled by same drive-by-wire ware. Because the same wire controller is used for controlling the indoor unit and the floor heating coil, compared with the prior common multi-split system, the multi-split system has the advantages of being simple in operation and avoiding hardware cost increase, but the control complexity is greatly improved. It should be noted that it is within the scope of the present application that the indoor units and the floor heating coil in different rooms use the same wire controller.
And the wire controller is used for outputting a control signal containing the floor heating coil and a corresponding target operation mode of the indoor unit. The target operation mode is an operation mode input by a user through a current wire controller and comprises a refrigeration mode, a heating mode, a dehumidification mode, a floor heating mode, an air conditioner floor heating mode and a floor heating dehumidification mode.
The cooling mode, the heating mode and the dehumidification mode are modes of only starting the indoor unit but not starting the floor heating coil, and the specific mode content is the same as that of a common air conditioner.
The floor heating mode is a mode that only the floor heating coil is opened but the indoor unit is not opened, and the opening of the floor heating coil is mainly realized by controlling the corresponding electric heating actuator (or electromagnetic valve) to be opened by the wire controller, so that hot water in a water supply pipeline enters the floor heating coil through the water distributor to circulate, and floor heating is realized.
The air conditioner floor heating mode is a mode of simultaneously starting an indoor machine heating mode and a floor heating mode, and the operation mode can be input integrally or separately. For example, the control signal containing the mode can be sent by directly inputting the air conditioner floor heating mode through the wire controller, or the control signal containing the mode can be sent by inputting the floor heating mode in the heating mode, or the control signal containing the mode can be sent by inputting the heating mode in the floor heating mode.
The floor heating dehumidification mode is a mode of simultaneously starting the dehumidification mode of the indoor unit and the floor heating coil, and the operation mode can be input integrally or separately. For example, the wire controller can be directly input into a floor heating dehumidification mode to send out a control signal containing the mode, or input into the dehumidification mode to send out a control signal containing the mode. The dehumidification function of mainly using under this mode, when the user used the dehumidification function, the room had the condition of cooling, and traditional dehumidification of not cooling down is the cold wind heating that uses auxiliary electric heater to blow off, and can open the warm water module that warms up in this application, with the waste heat with the room intensification, makes the environment of dehumidification more comfortable.
It should be noted that the wire controller provided by the present application can control the opening of the corresponding indoor unit and the floor heating coil (i.e. in the same room) at the same time, but the use of a plurality of wire controllers to achieve the same effect of the present application does not exceed the protection scope of the present application.
In order to avoid mode conflict, a target operation system of the outdoor unit needs to be determined according to a target operation mode contained in the control signal, and only when the target operation system is consistent with the current operation system of the outdoor unit, the controller can determine the operation state of the outdoor unit according to the control signal and control the floor heating coil and the corresponding indoor unit to operate according to the target operation mode. And when the target operation system is inconsistent with the current operation system of the outdoor unit, maintaining the operation state of the outdoor unit and outputting a mode conflict alarm signal.
The target operation system is an operation system that the control signal wants the outdoor unit to execute, and the current operation system is an operation system that the outdoor unit is currently executing. The operation system of the outdoor unit includes a heating system and a cooling system, in which the flowing directions of the refrigerant (refrigerant) in the refrigerant circulating pipes are different, and the functions of the outdoor heat exchanger are different.
In order to obtain a target operation system of the outdoor unit, in some embodiments, the determining the target operation system of the outdoor unit according to the control signal specifically includes: if the target operation mode is a heating mode, a floor heating mode or an air-conditioning floor heating mode, the target operation system is a heating system; and if the target operation mode is a refrigeration mode, a dehumidification mode or a floor heating dehumidification mode, the target operation system is a refrigeration system.

In the air-conditioning state, the outdoor unit does not open the floor heating water module, the water pump is not started, the water module expansion valve is closed, and the outdoor unit basically has the same operation mode as the common air-conditioning outdoor unit.
In a floor heating state, the outdoor unit opens the floor heating water module, the water pump is started, the expansion valve of the water module is opened, the four-way valve of the outdoor unit is conducted, the refrigerant circulation direction of the outdoor unit is the heating circulation direction, and the refrigerant in the outdoor unit mainly enters the sleeve heat exchanger to exchange heat with water in the floor heating water module, so that the refrigerant circulation pipeline is blocked, and the refrigerant does not enter the outdoor unit.
The air conditioner is similar to the floor heating state, the refrigerant circulation direction of the outdoor unit is still the heating circulation direction, and the difference is that the refrigerant circulation pipeline is smooth, and the refrigerant can enter the indoor unit through the refrigerant circulation pipeline.
The outdoor unit refrigerant circulation direction in the ground heating dehumidification state is the refrigeration cycle direction, the opening of the ground heating water module is different from the ground heating state in the state, the four-way valve of the outdoor unit is not conducted, namely the outdoor unit refrigerant circulation direction is still the refrigeration cycle direction, the refrigerant is controlled to enter the sleeve heat exchanger only through the water module electronic expansion valve, the sleeve heat exchanger is used as a condenser to assist the outdoor heat exchanger to participate in the refrigeration cycle, namely, the waste heat in the refrigerant is utilized to heat the water in the ground heating water module.
In some embodiments, the controller is further configured to: and if the outdoor unit does not operate, directly determining the operating state of the outdoor unit according to the control signal, and controlling the floor heating coil and the corresponding indoor unit to operate according to the target operation mode.
When the controller receives the control signal for the first time or the outdoor unit does not operate, the current operation system is empty, and the control signal can be directly executed without the mode conflict problem. It should be noted that when only one line controller switches the mode, the outdoor unit is equivalent to a non-operating state.
In some embodiments, the mode conflict warning signal may control the line controller to display the mode conflict warning message, and simultaneously control the indoor unit to enter a standby mode, or enter a mode suitable for the outdoor unit to operate according to a preset instruction.
In some embodiments, determining the operation state of the outdoor unit according to the control signal includes:
if the target operation mode and all current operation modes are operated without a floor heating mode, the operation state of the outdoor unit is an air-conditioning state;
and if only the floor heating mode is operated in the target operation mode and all the current operation modes, the operation state of the outdoor unit is the floor heating state.
The floor heating mode is not opened in all the rooms, only the indoor unit is started in the refrigerating mode, the heating mode or the dehumidifying mode, and the outdoor unit is in the same operation mode as the common air conditioner and enters the air conditioning state.
One or more rooms are started in a floor heating mode, indoor units of all the rooms are not opened, a water pump in a floor heating water module, a water module electronic expansion valve and a water module temperature sensor are controlled correspondingly at the moment, and the outdoor unit enters a floor heating state at the moment.
