Novel solar-ground source heat pump combined air conditioning system

Abstract

The invention provides a novel solar-ground source heat pump combined air conditioning system. The novel solar-ground source heat pump combined air conditioning system comprises a solar water heating system and a ground source heat pump system; the solar water heating system comprises a heat collector, cold water, a heat storing water tank, domestic hot water, a C circulating pump, a B valve, a C valve and a D valve; the ground source heat pump system comprises a buried pipe system, an A circulating pump, a heat exchange system, an A valve, a B circulating pump and an indoor air conditioning system. The novel solar-ground source heat pump combined air conditioning system can perform refrigerating in summer and heating in winter; domestic hot water can be provided all the year round; the building energy consumption can be effectively reduced, and thus the energy can be saved for the building.

Description

technical field [0001] The invention relates to the technical field of building energy conservation, in particular to a novel solar energy-ground source heat pump combined air conditioning system. Background technique [0002] With the development of the times and the advancement of technology, people have put forward higher and higher requirements for the comfort of the indoor environment and living conditions, which has brought about an increasing demand for heating, cooling and hot water supply in various buildings in cities and towns. . The traditional building cooling system is realized by central air-conditioning or small single-unit air-conditioning system, while heating and hot water supply are mostly completed by central heating system. Relevant data show that my country's building energy consumption accounts for more than 30% of the total energy consumption, while heating and air conditioning energy consumption accounts for 50-70% of building energy consumption. ...

AI Technical Summary

Problems solved by technology

For the solar ground source heat pump combined energy supply system designed to meet the heating demand, it is generally necessary to reasonably match the radiator area to ensure the balance of the ground temperature, but this system cannot meet the cooling demand of the building, so it is difficult to achieve a system at the same time The purpose of comprehensive energy supply

For the solar ground source heat pump combined building energy supply system designed to meet both heating and cooling needs, a single heat pump unit is generally used at present. On the one hand, solar heat storage in the system will affect the use of ground source heat pumps in summer. On the other hand, when the heating load of the building is much greater than the cooling load, the long-term operation of the system will inevitably lead to the destruction of the ground temperature balance.
