As shown in fig. 10, there is shown a control method for the energy system provided in the foregoing embodiment according to an exemplary embodiment. The method comprises the following steps:

step S1001, a condenser temperature, an evaporator temperature, and a measured temperature of the terminal heat exchanger of the temperature adjustment device are acquired.

Step S1002, controlling the opening degree of a first heat conducting valve of the terminal heat exchanger according to the temperature of the condenser and the measured temperature; and/or controlling the opening degree of a second heat conduction valve of the terminal heat exchanger according to the temperature of the evaporator and the measured temperature.

In the embodiment of the invention, the energy system comprises a temperature adjusting device and a terminal heat exchanger, the terminal heat exchanger is arranged in the water heater, the terminal heat exchanger can adjust the temperature of the water heater by utilizing energy generated by a condenser and an evaporator of the temperature adjusting device, and the energy generated by the temperature adjusting device is utilized to adjust the temperature of the water heater under the condition of meeting the normal work of the temperature adjusting device, so that the energy is saved.

In an optional embodiment, in step S1002, controlling an opening degree of a first heat-conducting valve of the end heat exchanger according to the condenser temperature and the measured temperature includes: and when the difference value obtained by subtracting the measured temperature from the condenser temperature is smaller than a set temperature value, closing the first heat conduction valve. In step S1002, controlling an opening degree of a second heat transfer valve of the terminal heat exchanger according to the evaporator temperature and the measured temperature, including: and when the difference value obtained by subtracting the temperature of the evaporator from the measured temperature is smaller than the set temperature value, closing the second heat conduction valve.

The effective operation of the temperature regulation device should be taken into account when utilizing the energy generated by the temperature regulation device. When the energy of the condenser of the temperature adjusting device is utilized by the terminal heat exchanger, and the difference value of the measured temperature of the terminal heat exchanger subtracted from the temperature of the condenser is smaller than the set temperature value, the temperature of the terminal heat exchanger cannot be effectively increased by the condenser, at the moment, the first heat conducting valve is closed, and the heat exchange between the condenser of the temperature adjusting device and the terminal heat exchanger is stopped. And when the difference value obtained by subtracting the measured temperature from the condenser temperature is greater than the set temperature value, the first heat conduction valve is opened again.

When the energy of the evaporator of the temperature adjusting device is utilized by the terminal heat exchanger, and the difference value obtained by subtracting the temperature of the evaporator from the measured temperature of the terminal heat exchanger is smaller than the set temperature value, the temperature of the terminal heat exchanger cannot be effectively reduced by the evaporator, at the moment, the second heat conduction valve is closed, and the heat exchange between the evaporator of the temperature adjusting device and the terminal heat exchanger is stopped. And the temperature of the evaporator of the temperature adjusting device is reduced along with the operation of the temperature adjusting device, and when the difference value obtained by subtracting the temperature of the evaporator from the measured temperature of the terminal heat exchanger is larger than the set temperature value, the second heat conduction valve is opened again.

When adjusting the aperture of second heat conduction valve, still include: and controlling the opening degree of a first heat conducting valve of the terminal heat exchanger according to the temperature of the condenser and the measured temperature.

Specifically, when the measured temperature minus the target temperature is greater than a first set temperature difference, the opening of the first heat conduction valve is reduced or the first heat conduction valve is closed, and if the measured temperature minus the evaporator temperature is greater than a second set temperature, the second heat conduction valve is opened or the opening of the second heat conduction valve is increased. Wherein the greater the measured temperature minus the target temperature, the greater the opening of the second thermally conductive valve.

The target temperature is set by the user according to the requirement, and in daily life, the target temperature is less than or equal to the body temperature of the user, and the sleeping comfort of the user is influenced by too low or too high target temperature, so that the experience of the user is reduced. Optionally, the target temperature is 25 ℃ to 35 ℃. Preferably, the target temperature is 25 ℃, 27 ℃, 30 ℃, 32 ℃ or 35 ℃.

When the measured temperature minus the target temperature is greater than a first set temperature difference, the temperature of the water heater is higher than the ideal temperature of a user, and the temperature of the water heater needs to be reduced, so that the opening degree of the heat conduction valve is reduced to slow down the heat exchange rate of the condenser and the terminal heat exchanger, or the heat conduction valve is closed to interrupt the heat exchange of the condenser and the terminal heat exchanger.

When the measured temperature minus the target temperature is less than or equal to a second set temperature difference, the temperature of the water heater is lower than the ideal temperature of a user, and the temperature of the water heater needs to be increased. Therefore, when the difference between the condenser temperature and the measured temperature is greater than or equal to a set temperature value, the heat conduction valve is increased.

When the measured temperature subtracts that the target temperature is less than or equal to a second set temperature difference, the condenser temperature subtracts that the difference of the measured temperature is less than a set temperature value, if the opening of the heat conduction valve is maintained unchanged, the temperature of the water heater cannot be increased, even the temperature of the water heater is reduced, at this moment, the opening of the heat conduction valve is reduced to slow down the heat exchange rate of the condenser and the terminal heat exchanger, or the heat conduction valve is closed to interrupt the heat exchange of the condenser and the terminal heat exchanger, the condenser temperature is increased along with the operation of the temperature adjusting device, and when the difference of the measured temperature subtracted from the condenser temperature is greater than or equal to the set temperature value, the heat conduction valve is.

In an alternative embodiment, the method further comprises: controlling the operating frequency of the thermostat compressor based on the condenser temperature, the measured temperature, and the target temperature.

Specifically, when the target temperature subtracted from the measured temperature is greater than a first set temperature difference, the operating frequency of the compressor of the temperature regulation device is reduced; and when the measured temperature minus the target temperature is less than or equal to a second set temperature difference, increasing the working frequency of the compressor of the thermostat.

When the measured temperature minus the target temperature is greater than the first set temperature difference, the temperature of the water heater is higher than the ideal temperature of a user, and the temperature of the water heater needs to be reduced, so that the working frequency of a compressor of the temperature adjusting device is reduced, the temperature of a condenser of the temperature adjusting device is reduced, and the heat exchange rate of the condenser and the terminal heat exchanger is slowed down.

When the measured temperature minus the target temperature is less than or equal to a second set temperature difference, the temperature of the water heater is lower than the ideal temperature of a user, and the temperature of the water heater needs to be increased, so that the working frequency of a compressor of the temperature adjusting device is increased to increase the temperature of a condenser of the temperature adjusting device and accelerate the heat exchange rate of the condenser and the terminal heat exchanger.
