Hot water machine system and control method thereof

Abstract

The invention discloses a hot water machine system and a control method thereof. The hot water machine system comprises a main machine, a solar water heater, a water tank and a heating system, whereinthe main machine is provided with a waterway end; the waterway end of the main machine is connected with the water tank and the heating system; and the water tank is connected with the solar water heater. According to the hot water machine system and the control method thereof, the solar water heater and the main machine are arranged, using the solar water heater or using electricity to heat thewater tank is selectable in different electricity time periods, so that the electricity utilization strategy is adjusted, the hidden danger of frequent startup and shutdown of the system is eliminated, the service life of the system is prolonged, the operation reliability of the system is improved, the use safety and comfort of the system are improved, and the use energy efficiency of the system is improved; and moreover, the energy consumption and the electric charge of a user can be reduced, so that the use cost of the user is reduced, the use satisfaction degree of the user is improved, andthe function load shifting is achieved.

Description

technical field [0001] The invention relates to the technical field of water heaters, and more specifically relates to a water heater system and a control method thereof. Background technique [0002] At present, the energy consumption of air conditioners accounts for about 20% of the city's electricity consumption, and energy saving and consumption reduction have become the most difficult problem to solve. At the same time, many cities have also introduced electricity price adjustment policies for different time periods. Specifically, electricity prices are more expensive during peak periods of daytime and nighttime consumption, and electricity prices are cheaper during low-peak periods of electricity consumption in the early morning and morning. For example, the following table shows the electricity price policy of a certain city: [0003] [0004] Multifunctional water heaters are large energy consumers, especially the uninterrupted switching between hot water heating...

AI Technical Summary

Problems solved by technology

[0004] Multifunctional water heaters are large energy consumers, especially the uninterrupted switching between hot water heating and air-conditioning heat pump functions, which seriously affects the energy efficiency of the unit, and frequent operations such as switching on and off will also reduce the life of the unit (the heating function of the multifunctional water heater , The cooling function and the hot water heating function, the operating status of the unit is different, and the function needs to be switched after shutdown), which reduces the reliability of use

At the same time, the cost of user use will also increase significantly, which will affect the user experience
