Heat storage type solar ground source heat pump

Abstract

The invention discloses a heat storage type solar ground source heat pump which comprises a solar thermal collector, a solar water storage tank, a temperature conversion water storage tank, a heat pipe exchanger, a water separator, a water collector, a ground heat exchanger, a heat pump unit and an indoor unit. The heat storage type solar ground source heat pump provided by the invention can meet the requirements of refrigeration, heat supply and domestic hot water supply, wherein a solar heat collecting system can realize heat storage seasonally, the temperature conversion water storage tank can realize high-quality heat supply in winter, and replace absorption type or adsorption type refrigeration equipment using solar hot water as driving force in the conventional solar ground source heat pump system in summer, the condensation heat is recycled by adopting a film falling method for heat exchange so as to realize efficient refrigeration, therefore, the intermittent operation of the ground source heat pump system and the heat storage type solar system is adopted, the recovery of an underground temperature field is facilitated, accordingly the heat exchange efficiency of a buried pipe is improved, and the service life of the ground source heat pump system is prolonged.

Description

technical field [0001] The invention relates to a solar ground source heat pump, in particular to a heat storage type solar energy ground source heat pump. Background technique [0002] The "Twelfth Five-Year Plan Outline for Land and Resources" issued on May 19, 2011 pointed out that during the "Twelfth Five-Year Plan" period, energy and mineral exploration should be strengthened, resources should be conserved, new energy developed, and renewable energy technology research and development and use should be increased. . At the beginning of the 21st century, my country began the practice of ground source heat pump projects, basically increasing at a rate of 20% to 25% per year. The ratio of the heat absorbed by the underground is 2.36. Continuous long-term operation will take too much heat from the underground or dissipate too much heat to the underground, causing fluctuations in the underground temperature field, reducing the COP value of the unit, and increasing the energy ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortage of existing ground source heat pumps that take heat from the ground or release heat to the ground for a long time when they work alone, which will cause unbalanced underground cold and heat loads, affect the heat exchange efficiency of the ground pipe heat exchanger, and increase the energy consumption of the system, the present invention Provide a heat storage type solar ground source heat pump, in which the solar heat collection system and the ground source heat pump system are coupled to operate, not only can realize the traditional refrigeration, heating and domestic hot water supply, but also can recover condensation heat in the system , to achieve efficient use of energy
