Abstract

The invention provides an air-conditioning system. The air-conditioning system comprises an indoor unit, a ground source heat pump unit, an air source heat pump unit and a controller, wherein the ground source heat pump unit is communicated with the indoor unit, the air source heat pump unit is communicated with the indoor unit, the ground source heat pump unit comprises a buried pipe heat exchanger, and the air source heat pump unit is communicated with the buried pipe heat exchanger. The controller is connected with the indoor unit, the ground source heat pump unit and the air source heat pump unit, and the air source heat pump unit is started within a low electricity price time period to store energy to the soil through the buried pipe heat exchanger. The low electricity price at night is utilized to perform soil cold accumulation or heat accumulation, system peak value cooling and heating loads can be effectively adjusted, energy is stored during the low electricity price period, electricity is used when the electricity price is high, running efficiency is improved, and the running cost is reduced.

Description

Technical field [0001] The present invention relates to the field of air conditioning, in particular, to an air conditioning system. Background technique [0002] In the context of increasingly scarce world energy, the existing ground-source heat pump technology cannot effectively improve the operating efficiency of the central air-conditioning system and the operating cost is high. Long-term operation will also cause the soil temperature to continue to increase or decrease, the energy efficiency of unit operation will decrease, and the energy-saving effect will deteriorate. Summary of the invention [0003] The purpose of the present invention is to provide an air conditioning system to solve the technical problems of low operating efficiency and high operating cost of the existing ground source heat pump technology. [0004] In order to achieve the above objective, the present invention provides an air conditioning system, including an indoor unit; a ground source heat pump unit,...
