When the air conditioner dehumidifies, the second refrigerant heat exchanger 60 is enabled to evaporate and absorb heat, the temperature of water in the first water circulation pipeline is reduced, and the first coil heat exchanger 20 can dehumidify the air flow; the second coil heat exchanger 30 can heat the air flow by evaporating the second refrigerant heat exchanger 60 to absorb heat and raise the temperature of the water in the second water circulation line. The hot water adopted for heating is sourced from a heat recovery system for condensation measurement, so that the energy consumption of the whole machine can be reduced. In this way, the temperature of the air flow is reduced to condense moisture in the refrigerant, and then the temperature of the air flow is raised to restore the refrigerant to a proper temperature, so that the maximum air outlet temperature of 25 ℃ can be realized. For the transition season and the plum rain season, under the condition that the indoor heat load is small and refrigeration is not needed and only dehumidification is needed, compared with the problem of low dehumidification air outlet temperature of the traditional air conditioner, the technical scheme of the invention well solves the contradiction between heat and humidity.

At this time, the first refrigerant heat exchanger is used as an evaporation heat absorption function. When the ambient temperature is far lower than the set temperature, the water side bypass of the fan coil is opened, the fan coil and the floor heater 70 work simultaneously, the heating time is shortened, and rapid heating is realized. Optionally, in the technical solution of the present embodiment, the air-conditioning water system further includes a second heating mode, in which the second refrigerant heat exchanger 60 condenses and releases heat, and the second water circulation pipeline is connected to the floor heater 70 for heating. When the ambient temperature is close to the set temperature or the user goes out for a short time, the system automatically turns off the fan coil, and the floor heater 70 is used for heat exchange, so that radiation heat exchange in a working area is realized, and comfortable heating is realized.
As a more preferable embodiment, the air-conditioning water system further includes a third heating mode in which the first heating mode is started when a difference between the ambient temperature and the set temperature is greater than a first predetermined value; when the difference between the ambient temperature and the set temperature is smaller than a second preset value, the second heating mode is started. In this way, through judging the environment temperature and the set temperature, whether the first heating mode or the second heating mode is started can be automatically selected, so that the automation of comfortable heating is realized. Specifically, when the ambient temperature is far below the set temperature (generally greater than 5 ℃, and can be set), the fan coil water side bypass is opened through logic judgment, and the fan coil and the floor heater 70 are simultaneously fed with water, so that the fan coil and the floor heater 70 are opened. The fan coil heats the room height space, the floor heater 70 heats the lower space and has radiated heat to the human body, and the two are opened simultaneously, so that the heating time is shortened, and rapid heating is realized. Double-surface cooling and heating can quickly raise indoor temperature.
