The invention provides the heat pump unit capable of remote operation and good man-machine interface display effect and the control circuit thereof; the control circuit comprises a main circuit and a control main plate, the control main plate isconnected with a touch screen, a GPS module, a plurality of relays, a plurality of temperature sensors, a normally closed contact of a first thermal relay KH1, a normally closed contact of a second thermal relay KH2, an electronic oil pressure differential switch SP1, a low pressure switch SP2 and a high pressure switch SP3, and the GPS module is wirelessly connected with a mobile terminal; and the heat pump unit can be applied in the field of heating and cooling.

Description

technical field [0001] The invention relates to a heat pump unit with an Internet of Things function and a control circuit thereof, belonging to the technical field of heat pumps. Background technique [0002] A heat pump is a device that can obtain low-grade heat energy from nature, perform work through high-temperature energy, and provide high-grade heat energy that can be used by people. The heat pump unit must have a set of corresponding automatic protection devices to make the equipment work within the range of safe conditions and ensure the normal and reliable operation of the entire system. [0003] After the heat pump unit is put into operation, there is no real-time intelligent monitoring, and the operating personnel need to conduct regular inspections. Relying on on-site inspections by personnel to check the operating status of the system is inefficient and poor in real-time performance. The existing authorization announcement number is CN 207849875 U, and the na...
