It is high efficient, environmental protective and fully uses solar energy. The machine set includes heat preserving water tank, solar energy heat collecting machine, heat pump machine set, computer automatic controller, solar energy water outlet temperature sensor, water tank temperature sensor and water tank liquid level sensor. The heat preserving water tank and solar energy heat collecting machine are connected to form the solar energy heating circulating loop through the solar energy side water circulating pipeline. The heat pump machine set and heat preserving water tank are connected to form the heat pump heat circulating loop through the heat pump side water circulating pipeline. The computer automatic controller includes timer. Compared with the heat pump machine set, the solar energy heat collecting machine has the preferential heating right to the water inside of the heat preserving water tank. The water level of heat preserving water tank is controlled in time interval. After stopping solar energy heating, the heat pump heating can be permitted after the set time delay. This invention can be used in energy saving field.

Description

technical field [0001] The invention relates to an intelligent light energy heat pump type cold and hot water energy-saving unit and a control method. Background technique [0002] Solar energy is an inexhaustible renewable energy source, and using solar energy to produce hot water can save energy consumption to the greatest extent for users. The existing solar hot water systems in hotels, hotels and other places need to use auxiliary heaters, such as electric heaters, boilers, etc. This is because these places often need to supply sanitary hot water 24 hours a day. However, solar energy alone cannot meet the needs of hot water production, and the use of auxiliary heaters requires additional energy consumption, which is uneconomical and pollutes the environment. At present, there are energy-saving devices that use heat pump systems to produce hot water. Although they are more energy-saving and environmentally friendly than traditional electric heating, coal-fired, and oil-f...

AI Technical Summary

Problems solved by technology

The existing solar hot water systems in hotels, hotels and other places need to use auxiliary heaters, such as electric heaters, boilers, etc. This is because these places often need to supply sanitary hot water 24 hours a day. , relying on solar energy alone cannot meet the needs of hot water production, and the use of auxiliary heaters needs to consume additional energy, which is not economical and pollutes the environment

At present, there are energy-saving devices that use heat pump systems to produce hot water. Although they are more energy-saving and environmentally friendly than traditional electric heating, coal-fired, and oil-fired heating methods, the utilization of energy is still not sufficient. Hot water requires continuous work of heat pumps, which still consumes a lot of energy. large amount of non-renewable energy

In addition, there have also been devices that use solar energy for heat pump water heating systems. The existing solar heat pump water heating devices use solar energy to heat the working fluid, and use high-temperature working fluid to carry heat to heat to produce hot water, that is, regardless of whether the solar system is working or not. , the heat pump must be running, or if the heat pump is not running, the auxiliary heater still needs to be used, so the energy consumption is still large

Existing hot water systems often store a large amount of water in the hot water tank in order to ensure that users can obtain uninterrupted hot water, and cannot adjust the amount of stored hot water according to the actual water consumption, so they also consume more energy
