The application provides a multi-source switchable one-
machine four-state intelligent air conditioner hot water
system and a control method, and relates to the technical field of
heat pump air conditioner hot water systems.The
system comprises an integrated heat exchange host, a hot water tank, a cold water tank and an intelligent controller component.The integrated heat exchange host integrates core components such as a condensing unit, an evaporating unit, a compressor and a throttling device, and realizes the switching of four working
modes, namely air conditioner
refrigeration and hot water preparation, air conditioner heating and cold water preparation, cold and hot water preparation and air conditioner independent operation, through the on-off combination of four electromagnetic valves, the start-stop control of a
circulating pump and a fan;the intelligent controller automatically controls the states of components according to preset logic based on temperature signals collected by sensors and user instructions, and can also adjust the power of a variable frequency compressor and the opening degree of an
electronic expansion valve.The application solves the problems of single heat source and rigid energy utilization of traditional systems, realizes efficient operation in a wide working condition, improves the energy
utilization rate and meets the diversified use requirements of users.
