Abstract

The invention relates to a multi-connection air conditioning and floor heating system and a control method. The multi-connection air conditioning and floor heating system comprises an outdoor unit, indoor units, and wire controllers which are connected with the indoor units; the indoor units are connected with the outdoor unit through a refrigerant pipeline; the wire controllers are connected withthe outdoor unit; and the outdoor unit is also provided with a water supply pipeline parallel to the refrigerant pipeline. The multi-connection air conditioning and floor heating system further comprises floor heating water modules and floor heating control units corresponding to the floor heating water modules; the floor heating water modules comprise floor heating coil pipes and electromagneticvalves arranged between the floor heating coil pipes and the water supply pipeline; the floor heating control units are in communication connection with the outdoor unit; the output ends of the floorheating control units are connected with the control ends of the electromagnetic valves; and the floor heating control units monitor communication information sent to the indoor units by the wire controllers; according to the monitored communication information, the outdoor unit opens the refrigerant pipeline or the water supply pipeline; and the floor heating control units control the states ofthe electromagnetic valves. A floor heating mode or an air conditioning mode is selected by the wire controllers of the indoor units, so that the operation is simple and convenient, conflicts caused by misoperation are avoided, and the user experience is improved.

Description

technical field

[0001] The invention belongs to the technical field of multi-connected air-conditioning control, and in particular relates to a multi-connected air-conditioning floor heating system and a control method. Background technique

[0002] In many places where central heating is not available, more and more users use multi-connected air-conditioning systems to cool in summer and heat in winter. The hot air is delivered indoors, and the temperature of the heating air is uneven. The hot air is easy to concentrate on the part close to the ceiling, so that the room temperature drops from top to bottom. The user feels that the head is hot and the feet are cold. The wind pressure of the fan and the speed of the air supply make the overall indoor temperature reach the set value, which will lead to a significant increase in indoor noise and reduce the user's comfort in the process. With the expansion of the water machine market, more and more users choose the floor heatin...
