Abstract
A double direction energy accumulation type geothermal energy cold and warm central air-conditioning plant adapted for living accommodation and offices mainly comprising of a plurality of valves, water pumps, backwater pipes, inlet pipes, an outdoor heat exchanger, an indoor heat exchanger, a heat source well and a cold source well. In summer, all the valves are opened to start the water pumps, the cold underground water is pumped from the cold source well into the hot source well, the water flows through a plurality of parallel indoor heat exchangers and outdoor heat exchangers through guide conduits. In winter, some of the valves are shut down, the water pumps are started to pump the hot underground water from the hot source well into the cold source well, the water flows through a plurality of parallel indoor heat exchangers and outdoor heat exchangers through guide conduits.
Description
The present invention relates to a kind of ground can the changes in temperature central air conditioning plant.
(Chinese invention patent: deep-well cold-storage, water are the air-conditioning system of carrier to existing ground energy air conditioner device, applicant: Zhang Shuyun, application number: 9411141.8X, publication number: CN1106521A, the applying date: 94.8.18).The operation principle of this system is: dig two mouthfuls of deep-wells in place separated by a distance, the water that extracts winter in the deep-well is sent into another deep-well by after the cooling tower cooling, utilizes water refrigeration colder in one deep-well of back summer again.This scheme has solved as Chinese invention patent: the air-conditioning system of utilizing usderground water as coolant, applicant: Zhejiang Building Engineering Co. No.4, application number: 89108110, the authorization number: CN1016991B, the applying date: the defective in the technical scheme that 89.10.18 proposed: the underground water of utilization is natural temperature, be generally about 19 ℃, little with the heat exchange difference of air-conditioning air regulator, its available cold is limited, the increase that main is along with service life, stratum savings heat raises the underground water temperature, finally loses cooling-down effect.
The prior art deficiency is to need winter and extracts to send into another deep-well after water in the deep-well is by the cooling tower cooling, make winter higher relatively geothermal energy not make full use of and be wasted, there is not heat-production functions winter, and because of need construction cooling tower, increase construction cost and operating cost, also will take certain space.
The objective of the invention is to provide simple in structure, equipment manufacturing cost and operating cost are low, and summer can refrigeration, winter can pyrogenicity, and the ground that is easy to apply can the changes in temperature central air conditioning plant.
The object of the present invention is achieved like this: make a call to two mouthfuls of deep-wells separated by a distance underground, summer is from wherein extracting lower temperature underground water a bite deep-well, by conduit the flow through indoor heat converter and the outdoor heat converter of a plurality of parallel connections, play cooling room air and the phreatic effect of heating.And warmed-up underground water recharged in another mouthful deep-well by conduit.Extract higher temperature underground water winter again from a bite deep-well of back, by conduit the flow through indoor heat converter and the outdoor heat converter of a plurality of parallel connections, play heating room air and the phreatic effect of cooling.And chilled underground water recharged in preceding a bite deep-well by conduit.
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is the operation logic figure of system of the present invention
Among the figure: 1-valve, 1,2-valve, 2,3-valve, 3,4-valve, 45-water pump first, 6-water pump second, 7-return pipe, 8-water inlet pipe, 9-outdoor heat converter, 10-indoor heat converter, 11-thermal source well, 12-low-temperature receiver well.(arrow is represented water (flow) direction)
Use: summer: open valve 1 (1) and valve 4 (4), valve-off 2 (2) and valve 3 (3); Starting water pump second (6), when colder underground water pumps in the thermal source well (11) by conduit in low-temperature receiver well (12), water is by conduit the flow through indoor heat converter (10) and the outdoor heat converter (9) of a plurality of parallel connections, play cooling room air separately and the phreatic effect of heating, and make thermal source well (11) underground water temperature on every side than natural temperature height.Winter: open valve 2 (2) and valve 3 (3), valve-off 1 (1) and valve 4 (4); Starting water pump first (5), when the underground water of heat pumps in the low-temperature receiver well (12) by conduit in thermal source well (11), water is by conduit the flow through indoor heat converter (10) and the outdoor heat converter (9) of a plurality of parallel connections, play heating room air separately and the phreatic effect of cooling, and make low-temperature receiver well (12) underground water temperature on every side lower than natural temperature.Water pump first (5) or water pump second (6) make each outdoor heat converter (9) and indoor heat converter (10) both sides keep certain differential water pressures all the time, indoor heat converter (10) is when starting working, automatically open the valve of this indoor heat converter (10) water pipe, make current through corresponding outdoor heat converter (9) and indoor heat converter (10); Indoor heat converter (10) is when quitting work, and corresponding aqueduct valve is closed automatically.Because indoor heat converter (10) all is in parallel, their duty can be separate, is independent of each other.The indoor heat converter of a plurality of parallel connections (10) is connected with an outdoor heat converter (9), can heat or cool off underground water better like this, can save construction cost again.By opening or closing of by-pass valve control 1 (1), valve 2 (2), valve 3 (3) and valve 4 (4), make the colder underground water that extracts from low-temperature receiver well (12) is delivered in the thermal source well (11) by conduit, when delivering in the low-temperature receiver well (12) by conduit with a underground water of the heat that from thermal source well (11), extracts, water can both be sent into outdoor heat converter (9) and indoor heat converter (10) by water inlet pipe (8), flow out from return pipe (7) again, thereby guaranteed that each outdoor heat converter (9) and indoor heat converter (10) can both operate as normal.
The present invention is simple in structure, builds and operating cost is low, energy-conserving and environment-protective.Can make summer indoor temperature remain on 24～28 ℃, can make winter indoor temperature remain on (also available auxiliary heating improves room temperature) about 16 ℃～22 ℃.It is a kind of changes in temperature central air conditioner system that is applied to house and office.
