Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a ground source heat pump air conditioning system, which has the advantages of high efficiency, energy saving and environmental protection, and solves the problem of heat extracted from underground soil by a single ground source heat pump air conditioning system in relatively cold areas. It is greater than the heat discharged to the underground soil, resulting in a sudden thermal imbalance, which causes the soil temperature to drop year by year, resulting in a decline in the performance of the system in winter and even failure to supply heat normally. The problem

T1≤T2

[0041] T1 is the plate core temperature of the solar collector evaporator, T2 and T3 are the preset high temperature and low temperature of the solar collector evaporator core respectively, T4 is the water supply temperature of the air conditioner, and T5 and T6 are the preset water supply temperature of the air conditioner respectively. High and low temperatures.

[0042] The beneficial effects of the present invention are: by utilizing the solar heat source, long-term excessive heating from the underground soil can be avoided. Underground soil energy storage for excess heat when the intensity is sufficient; turn on the ground source heat pump heating mode on rainy days and nights in winter, turn on the ground source heat pump cooling mode in summer, and turn on the energy storage mode in the spring and autumn transitional seasons, and the air conditioning system always maintains efficient operation , save energy to the greatest extent, and ensure the continuous...

Description

technical field [0001] The invention relates to the technical field of ground source heat pump systems, in particular to a ground source heat pump operation management system and an implementation method. Background technique [0002] In recent years, due to concerns about environmental issues such as building energy saving, carbon dioxide emission reduction, and atmospheric smog improvement, ground source heat pump technology using renewable shallow geothermal energy has developed rapidly in the field of building air conditioning. Heat pump technology takes advantage of the huge heat capacity of the earth and the relatively stable underground soil temperature. It releases heat to the soil in summer and absorbs heat from the soil in winter through a closed-loop buried tube heat exchanger, and realizes cooling and heating of buildings through heat pumps. [0003] Ground source heat pump air conditioner is an energy-saving and environment-friendly ground source heat pump syste...
