Centralized heating and refrigerating system integrating solar energy, air energy and power grid

Abstract

The invention discloses a centralized heating and refrigerating system integrating solar energy, air energy and power grid, which is characterized in that solar cells and a power grid are simultaneously connected with a grid-connected inverter, the grid-connected inverter is connected with a double-source heat pump communicated with a freezing water tank and a heating water tank, two water tanks are both connected with a water supplementing tank, the heating water tank is connected with a constant-temperature hot water tank by a temperature control solenoid valve, the lower part of the constant-temperature hot water tank is connected with a constant-temperature air resource heat pump, and the freezing water tank and the constant-temperature hot water tank are both communicated with a usercoiler. A user exclusive IC card heat meter is arranged between a main pipe for refrigerating and heating and each user coiler, and a user exclusive IC card metering electronic water meter is arranged between the main pipe for refrigerating and heating and each user coiler, and a property management host is connected with each electronic water meter by communication equipment. The invention supplies hot water in 24 hours, and supplies heat and refrigerates in different seasons. The invention saves energy and has no pollution. A hot water system is managed uniformly by the property and has scientific and accurate metering.

Description

technical field [0001] The invention relates to a centralized hot water supply, refrigeration and heating system integrating solar energy, air energy and power grid high-rise buildings. Background technique [0002] Solar energy is an inexhaustible clean energy with the advantages of no noise and zero emissions, so solar photovoltaic power generation has a wide range of applications, but solar energy is intermittent and random, and there is a problem that solar cells occupy a large area And the generated electricity needs to be stored and other issues. At present, there are many solar photovoltaic power generation systems at home and abroad, which can be roughly divided into two methods: off-grid and grid-connected. If the power generated by a small area of ​​solar energy on the roof is input into the public grid, not only will there be a lot of technical management problems, but it will also affect the public grid. It is safe, so it is more economical and safe to use the g...

Problems solved by technology

Therefore, it still destroys the overall image of the building.

There are also air-conditioning systems used by users for heating and cooling, and there are also many independent systems, which occupy the user's housing area and other problems.

If central heating is used, there are also complicated and cumbersome charging problems
