The water temperature of floor heating is 40~45℃, and the temperature required for domestic hot water is generally between 55℃~80℃, that is, the temperature required for domestic hot water is relatively high, which will easily cause excessive exhaust pressure and excessive The temperature of the online system is too high, and the domestic hot water needs to be circulated and heated between the heat pump and the water tank. In the multi-connected system, as the temperature of the domestic hot water gradually increases, the exhaust pressure and exhaust temperature also increase. The rise of exhaust pressure and exhaust temperature introduces dynamic interference to most multi-coupled systems, causing the basic functions of multi-coupled refrigeration and heating to be impacted and negatively affected

A multi-split air conditioner system with a hydraulic module has both floor heating and domestic hot water. In the multi-split air conditioner system, the exhaust pressure and the exhaust temperaturealso increase along with gradual increase of the water temperature of domestic hot water, and dynamic interference is introduced into the large multi-split air conditioner system due to increase of the exhaust pressure and the exhaust temperature, so that most of basic functions of refrigeration and heating of the large multi-split air conditioner system are impacted, and negative effects are caused. A floor heating system and a domestic hot water tank are connected to an intermediate heat exchanger through connection, water in a domestic hot water tank is subjected to primary heating througha refrigerant of a multi-split air conditioner, the water in the domestic hot water tank is preheated to a certain temperature, and meanwhile a floor heating system can achieve the heating and warm-keeping effects on a room; and the domestic hot water tank is additionally subjected to secondary heating through a heat pump unit, so that the heat pump unit can bear dynamic interference of domestic hot water due to water temperature rise, the operation of a large multi-split air conditioner set is not influenced any more, and higher water temperature is realized.
Description
technical field [0001] The invention relates to the technical field of integration of water heaters and multi-connected air conditioners, in particular to a multi-connected system capable of heating domestic water and equipped with floor heating. Background technique [0002] At present, the air injection enthalpy multi-split with hydraulic module has been widely used in cold regions. The multi-split system has both floor heating and domestic hot water. The water temperature of floor heating is 40~45℃, and the temperature required for domestic hot water is generally between 55℃~80℃, that is, the temperature required for domestic hot water is relatively high, which will easily cause excessive exhaust pressure and excessive The temperature of the online system is too high, and the domestic hot water needs to be circulated and heated between the heat pump and the water tank. In the multi-connected system, as the temperature of the domestic hot water gradually increases, the exh...
