The floor heating converter is connected to a gas side pipe (high pressure) through one side of an electromagnetic valve of the floor heating converter, connected to a liquid side pipe through one side of an electronic expansion valve of the floor heating converter, and further connected to the multi-split air-conditioning system. When a user wants the multi-split system to realize a floor heating function, the multi-split system can be connected with the capillary network through the floor heating converter.
When the multi-split air conditioner is used for heating, the multi-split air conditioner heating and floor heating functions are achieved through opening of the electromagnetic valve of the floor heating converter and opening adjustment of the electronic expansion valve. The concrete flow direction that the refrigerant flows through the capillary network through the floor heating converter is as follows: the compressor, the oil separator, the gas side pipe (high pressure), the floor heating converter, the electromagnetic valve, the capillary network, the floor heating converter DPF (electronic expansion valve), the liquid pipe side, the subcooler, the outdoor DPF (electronic expansion valve), the outdoor heat exchanger, the second four-way valve 42, the gas separation compressor.

2. the modularization free combination of the multi-split air conditioning system can be realized through the local heating converter, and the method comprises the following steps:
when the multi-split air conditioner is used for heating, the multi-split air conditioner heating and floor heating functions are achieved through opening of an electromagnetic valve of a floor heating converter and opening adjustment of an electronic expansion valve. The concrete flow direction that the refrigerant flows through the capillary network through the floor heating converter is as follows: compressor-oil separator-first four-way valve 41-gas side pipe (high pressure) -floor heating converter-solenoid valve-capillary network-floor heating converter DPF-liquid pipe side-subcooler-outdoor DPF-outdoor heat exchanger-second four-way valve 42-gas separation-compressor.
And secondly, when the multi-split air conditioner is used for heating, if the floor heating function is not required to be started at the moment, the electromagnetic valve of the floor heating converter can be controlled to be closed. Closing of the electromagnetic valve can prevent the refrigerant from continuing to enter the capillary network through the floor heating converter, and the problem that the refrigerant is accumulated due to the fact that the refrigerant enters the capillary network is solved.
And thirdly, during multi-split air conditioner refrigeration, the floor heating function is not required to be started, and the electromagnetic valve of the floor heating converter and the electronic expansion valve can be controlled to be closed.
3. The multi-split heating and floor heating functions can be simultaneously realized through the floor heating converter. The basic valves in each case are controlled as in the table below, with the particular electronic expansion valve steps and the like being adjusted in accordance with operating parameters and the like.
4. When the multi-split system realizes the floor heating function, the refrigerant flows through the capillary network through the floor heating converter, and the specific flow direction is as follows: the compressor, the oil separator, the first four-way valve 41, the gas side pipe (high pressure), the floor heating converter, the electromagnetic valve, the capillary network, the floor heating converter DPF (electronic expansion valve), the liquid pipe side, the subcooler, the outdoor DPF, the outdoor heat exchanger, the second four-way valve 42, the gas separation and the compressor. When the multi-connected heat generator does not need a floor heating function, the refrigerant can still flow into the capillary network, and the flowing resistance of the refrigerant in the capillary network is very large due to the small pipe diameter and the large pipe length of the capillary network. Therefore, even if the electronic expansion valve at the end of the liquid pipe is opened to a certain degree, the refrigerant is still difficult to circulate in the capillary network, and the refrigerant is accumulated in the capillary network. To solve this problem, the local heating converter is provided with a solenoid valve at the inlet of the high pressure side pipe and the capillary network. When the multi-split heating system does not need a floor heating function, the refrigerant is prevented from continuously entering the capillary network through the floor heating converter by closing the control electromagnetic valve, and the problem that the refrigerant is accumulated as the refrigerant enters the capillary network is solved.
5. When the capillary network needs to be maintained due to faults caused by refrigerant leakage or pipeline blockage, the existing pipe connection mode and control method cannot prevent the external machine refrigerant from leaking on the basis of not influencing the use of other functions of the multi-split air conditioner. This ground heating converter is through newly-adding an solenoid valve, in coordination with original electronic expansion valve, when the capillary network need be maintained because of breaking down, closes completely simultaneously for the unable rethread ground heating converter of refrigerant of outer machine of many online flows to the capillary network. Therefore, when the capillary network is maintained independently, leakage of the multi-connected outdoor unit due to circulation of the refrigerant can be avoided, and influence on operation of other functions of the multi-connected outdoor unit due to maintenance of the capillary network can be avoided.
The above description is only exemplary of the present disclosure and should not be taken as limiting the disclosure, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present disclosure should be included in the scope of the present disclosure. The foregoing is only a preferred embodiment of the present disclosure, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present disclosure, and these modifications and variations should also be regarded as the protection scope of the present disclosure.
