the floor heating system is characterized by further comprising at least one floor heating module 9, wherein the floor heating module 9 comprises a heat exchange assembly 91, the heat exchange assembly 91 is communicated between the first gas side pipe 31 and the liquid side pipe 33, and a refrigerant can flow through the heat exchange assembly 91 to exchange heat for floor heating;

also included is a photovoltaic module 10, the photovoltaic module 10 being capable of absorbing solar energy and generating electrical energy for supply to the multi-split air conditioning system.

1. Common refrigerating and heating functional module

In some embodiments, the indoor unit 61 includes an indoor heat exchanger 611 and an indoor unit pipe 101, and the indoor heat exchanger 611 and the first throttling device 71 are disposed on the indoor unit pipe 101.

After being discharged from the compressor, the high-temperature and high-pressure gas is changed into medium-pressure and low-temperature liquid through the oil separator, the second four-way valve 42 and the outdoor heat exchanger, enters the ordinary indoor unit through the small valve of the liquid side pipe, is throttled, is evaporated and absorbs heat at the indoor side, performs refrigeration of the indoor unit, flows into the vapor-liquid separator through the second large valve 152 and the first four-way valve 41, and returns to the compressor. When the first four-way valve 41 and the second four-way valve 42 are powered and switched, the ordinary internal machine performs internal machine heating.

2. Heat storage defrosting module

In some embodiments, the heat storage module 62 includes a heat accumulator 621 and a heat storage pipeline 102, and the heat accumulator 621 and the second throttling device 72 are disposed on the heat storage pipeline 102.

The heat accumulation defrosting module is only used when the system is in heating operation. When the system is in a refrigerating mode or other modes of operation, the valve of the heat accumulation defrosting module is closed. When the system is in heating operation, the flow direction of a refrigerant in the system is the same as that of a common heating indoor unit, and the heat storage defrosting module is subjected to heat storage without influencing the heating effect of other indoor units by adjusting the opening degree of the electronic expansion valve in the heat storage defrosting module. When the outdoor unit needs defrosting operation, the valve of the common heating indoor unit is closed, the heat storage defrosting module is used for providing heat for defrosting, the defrosting does not take heat from the indoor space, and the indoor comfort is improved.

The heat and frost storage module can be selectively installed. If the master control of the air conditioning system detects that no heat storage defrosting module is connected into the system, executing common indoor defrosting during defrosting; when the heat storage defrosting module is detected to be connected, the system operates according to the set heat storage defrosting control logic, heat storage defrosting is executed during defrosting, and when the heat storage defrosting fails and defrosting cannot be completed, the system performs ordinary internal defrosting operation.

3. Constant temperature dehumidification module

In some embodiments, the thermostatic dehumidifying inner machine 63 comprises a first heat exchanger 631 and a second heat exchanger 632, the first heat exchanger 631 is disposed on a third pipeline 103, one end of the third pipeline 103 is communicated to the second gas-side pipe 32, the other end is communicated to the liquid-side pipe 33, the second heat exchanger 632 is disposed on a fourth pipeline 104, one end of the fourth pipeline 104 is communicated to the first gas-side pipe 31, and the other end is communicated to the liquid-side pipe 33.

After being discharged from the compressor, the high-temperature and high-pressure gas passes through the oil separator and is divided into two paths before entering the four-way valve: the first path passes through the second four-way valve 42 and the outdoor heat exchanger, becomes a low-pressure and medium-pressure liquid, passes through the small valve of the liquid side pipe, enters the constant temperature dehumidification module, is throttled by the third throttling device 73, and then is evaporated and absorbed in the first heat exchanger 631 to refrigerate the first heat exchanger 631. The second path directly enters the constant temperature dehumidification module through the first large valve 151 of the gas side pipe (high pressure), is condensed and releases heat in the second heat exchanger 632, passes through the fourth throttling device 74, is converged with the first path of refrigerant entering the third throttling device 73, and is evaporated and absorbs heat in the first heat exchanger 631.

The two paths are merged into one path, and then flow into the vapor-liquid separator through the second large valve 152 and the first four-way valve 41, and then return to the compressor. Due to the common condensation dehumidification system, the temperature of the air can be reduced simultaneously when dehumidification is carried out. The lower air-out temperature reduces the travelling comfort that the user used. When passing through the constant temperature dehumidification module, the high temperature (medium temperature) and high humidity air is firstly dehumidified and cooled at the first heat exchanger 631, and then is heated at the second heat exchanger 632, so that the outlet air temperature and humidity can be always kept in a comfortable range, and the use experience of a user is improved.

When the constant temperature dehumidification module needs to heat, the first four-way valve 41 and the second four-way valve 42 are powered to change directions, the flow direction of the refrigerant in the first heat exchanger 631 is consistent with that of the ordinary refrigerating and heating indoor unit, the refrigerant condensed and released in the second heat exchanger 632 is converged after being condensed and released in the first heat exchanger 631, and then the refrigerant returns to the outdoor heat exchanger through the liquid side pipe to be evaporated and then returns to the compressor. Compared with the common indoor heating, the constant-temperature dehumidification module has better heating effect because the number of the heat exchangers is two.

When the system detects that the constant temperature dehumidification module is accessed, the air conditioning system main control executes the constant temperature dehumidification function according to the mode requirement set by the user. If the system does not access the module, the system does not have the function, and the user can not set the function. Other functions accessed in the system are not influenced, and the other functions can be normally realized.

The system can provide domestic hot water regardless of any mode. After being discharged from the compressor, the high-temperature and high-pressure gas passes through the oil separator and enters the domestic hot water module from the first large valve 151 of the gas-side pipe (high pressure). Enters the water tank through the electromagnetic valve A to heat the domestic hot water.

(2) The system has the requirements of refrigeration and hot water production, and the refrigerant is evaporated and absorbs heat in an inner machine with the refrigeration requirement after heating the hot water and then returns to the compressor. Or the refrigerant enters the indoor heat exchanger and the outdoor heat exchanger to evaporate and absorb heat together and then returns to the compressor (which mode is selected and can be determined according to the total requirements of hot water production and refrigeration).

(3) The system has the requirements of heating and hot water production, a part of high-temperature and high-pressure refrigerant discharged from the compressor heats hot water by the hot water removing module, and the other part of the high-temperature and high-pressure refrigerant is condensed at the indoor side to release heat and then returns to the outdoor unit to be evaporated and then returns to the compressor.

When a hot water module is accessed in the system, the main control of the air conditioning system executes hot water function operation according to the hot water temperature and the hot water quantity requirement set by a user. If the system is not connected with the hot water module, the system has no function, other functions connected in the system are not affected, and other functions can be normally realized.
