Description
Technical field
The invention belongs to natural energy and utilize technical field, particularly a kind of assembly that utilizes natural energy to adjust underground heat storage body temperature degree.
Background technology
The building in the most of area of China all needs Winter heat supply, summer cooling.The energy resource consumption of heating and cooling is very huge, the energy security of China has been caused serious prestige association, and caused serious environmental issue.The energy resource consumption that reduces building is a long-term task and problem.
Summary of the invention
The purpose of this invention is to provide a kind of adjustment temperature of underground cold/heat accumulation body assembly, before heat supply in winter arrives, by discharging a large amount of heats to the underground heat storage body, improve its temperature, it is spontaneous or non-from the ability that is sent to building transmission heat that it is had, before the arriving of summer cooling phase as far as possible, by taking out a large amount of heats from heat storage, reduce its temperature as far as possible, make it have spontaneous and non-spontaneous ability, realize that low energy consumption is building cooling/heat from the building heat removal.Final realization utilizes natural cold and heat source, reduces the purpose of building energy consumption.
The objective of the invention is to be achieved through the following technical solutions, it comprises underground cold/heat accumulation body 1, buried heat exchanger 2, circulating pump 3, connected system pipeline and working medium, dividing wall type air heat exchanger 4, cold/heat supply load heat exchanger 5, stop valve 6,7, it is characterized in that: buried heat exchanger 2 is installed in the cold/heat accumulation body 1, closely contact with cold/heat accumulation body 1, circulating pump 3 is serially connected between buried heat exchanger 2 and dividing wall type air heat exchanger 4 that is connected in parallel and the cold/heat supply load heat exchanger 5, and the import or export of dividing wall type heat exchanger and cold/heat supply load heat exchanger is connected to the stop valve that control working medium flows into or flows out.
Operation principle of the present invention
Summer cooling: circulating pump 3 work, stop valve 7 is opened, cycle fluid will enter in the buried heat exchanger from the heat of spontaneous heat transfer of cold/heat supply load heat exchanger or non-spontaneous heat transfer acquisition, and pass to underground cold/heat accumulation body 1, make its temperature rise, when the summer environment temperature is lower than buried intraductal working medium temperature, circulating pump 3 and stop valve 6 are opened, the blower fan of dividing wall type air heat exchanger is opened, make working medium pass through dividing wall type heat exchanger, emit heat, return buried heat exchanger after the cooling to air, reducing the temperature of heat storage, is that second day cooling is prepared.
When summer cooling finishes, component system enters and obtains the heat operating mode, utilize automatic control system, the temperature difference by working medium in perception dividing wall type air heat exchanger and the buried heat exchanger, opening of commander's circulating pump and dividing wall type air heat exchanger blower fan, stop, when the temperature of working medium in the pipe laying above Ground of working medium temperature in the dividing wall type air heat exchanger, the temperature difference surpasses when setting heat transfer temperature difference, the blower fan of dividing wall type air heat exchanger, circulating pump 3, stop valve 6 is opened, collect the heat of surrounding air continuously, and heat passed to underground heat storage body 1, its temperature is risen, for heat supply in winter is prepared.
During heat supply in winter, circulating pump work, stop valve 7 is opened, and the heat that the underground heat storage body is stored passes to cold/heat supply load heat exchanger by systematic working medium, by spontaneous or non-spontaneous heat transfer process, passes to building again, finishing the heating circulation.This season is if ambient air temperature is higher, to the temperature that makes working medium in the dividing wall type air heat exchanger temperature of working medium in the pipe laying above Ground, when its temperature difference during greater than the heat transfer temperature difference set, circulating pump is opened, stop valve 6 is opened, the blower fan of dividing wall type air heat exchanger is opened, and the heat of collecting surrounding air is used to heat underground cold/heat accumulation body and heating.
After Winter heat supply finishes, system enters the discharges heat operating mode, the temperature of working medium is lower than the temperature of buried intraductal working medium in the dividing wall type air heat exchanger, its temperature difference is during greater than the heat transfer temperature difference set, and circulating pump is opened, and stop valve 6 is opened, dividing wall type air heat exchanger blower fan is opened, the heat of underground heat storage body is discharged, and make the underground cold/heat accumulation body cooling, for summer cooling is prepared.
Select the dividing wall type air heat exchanger and the ground heat exchanger of suitable heat exchange area that the temperature of the preceding cold/heat accumulation body of heating is on the higher level, might realize spontaneous heat transfer heating, the heat supply energy consumption of this moment is extremely small, both made and utilized non-spontaneous diabatic process, utilize heat pump to absorb the heat of heat storage, heat supply after heating up, its coefficient of performance also can significantly rise, and power consumption will decline to a great extent.
Equally, the preceding cold/heat accumulation body temperature of cooling is on the enough low level, may realizes spontaneous heat transfer cooling fully, the cooling of this scheme consumes energy hardly.
Application of the present invention is pushed building energy conservation cooling/thermal technology to a brand-new height, can obtain the considerable energy saving emission reduction effect.
