Referring to fig. 1, an embodiment of the present invention provides an integrated compressor and heater structure 100, including: an integration module 101 and an execution module 102.
Wherein the integrated module 101 comprises: MCU1011, heater power control module 1012, and compressor power control module 1013.
The execution module 102 includes: a heat generating unit 1021, a first sensor 1022, an execution unit 1023, and a second sensor 1024.
The MCU1011 is configured to generate a request current signal and transmit the request current signal to the heater power control module 1012 and the compressor power control module 1013; the request current signal represents the heating requirement or the cooling requirement of the new energy automobile.
In one example, the MCU is manually started according to the environment in the new energy automobile, namely the MCU provides a heating demand or a refrigerating demand manually according to the environment in the new energy automobile, and the MCU generates a request current signal according to the heating demand or the refrigerating demand manually provided.
The MCU can be started in various modes, such as connecting a performance source automobile through electronic equipment, remotely controlling the starting of the MCU, and starting the MCU through a button on a new energy automobile.
The external power supply includes: a first power supply and a second power supply; the first power supply is used for supplying high-voltage current; the second power supply is used for providing low-voltage current. The first power source may be a battery pack; the second power supply may be a low voltage battery. The low-voltage current is provided for the MCU, the first sensor and the second sensor, and the high-voltage current is provided for the heater power control module, the compressor power control module, the heating unit and the execution unit. Of course, the high-voltage current provided in the first power source may be converted into a low-voltage current by the dc converter to be provided to the MCU, the first sensor, and the second sensor.
The MCU1011 generates a request current signal and controls high-voltage current provided by the external power supply to flow into the heating unit 1021 through the heater power control module 1012, and the heating unit converts the high-voltage current into heat, so that the purpose of supplying heat to a new energy automobile is achieved. The heat generating unit 1021 according to the present embodiment includes at least: a heating resistor and a heating film.

The MCU1011 receives the first signal or the second signal, and determines whether the temperature of the heating unit 1021 or the execution unit 1023 is greater than a first preset value.
If the MCU1011 receives the first signal or the second signal and then determines that the temperature of the heat generating unit 1021 or the executing unit 1023 is greater than the first preset value, the MCU1011 reduces the temperature of the heat generating unit 1021 or the executing unit 1023 by reducing the operating frequency of the heater power control module 1012 or the compressor power control module 1013.
If the MCU1011 receives the first signal or the second signal and then determines that the temperature of the heat generating unit 1021 or the executing unit 1023 is lower than the first preset value, the MCU1011 increases the frequency of the heater power control module 1012 or the compressor power control module 1013 to increase the operation of the heat generating unit 1021 or the executing unit 1023. The operation means that after the current flows through the heating unit or the execution unit, the heating unit heats or the execution unit continues to move.

the MCU is further configured to: receiving the third signal and judging whether the rotating speed of the compression motor exceeds a second preset value, if so, reducing the rotating speed of the compressor motor through the compressor power control module; and if not, increasing the rotating speed of the compressor motor through the compressor power control module.
8. The integrated compressor and heater structure of claim 7, wherein the first sensor and the second sensor are temperature sensors; the third sensor is a speed sensor.
9. The integrated compressor and heater structure according to claim 1, wherein the heat generating unit includes at least: a heating resistor and a heating film.
10. An automobile characterized by comprising an integrated structure of a compressor and a heater as set forth in any one of claims 1 to 9.
