Utilize air conditioning air exhaust to subdue and inhale the unbalanced device of heat release summer in underground pipe winter
Technical field
The utility model relates to earth-source hot-pump system, specifically a kind ofly utilizes air conditioning air exhaust to subdue to inhale the unbalanced device of heat release summer in underground pipe winter.
Background technology
Source pump is in annual operation process, and will absorb a large amount of heats discharged to soil layer (heat release) summer by the underground pipe circulation; Then extract stratum heat energy (heat absorption) by the underground pipe circulation winter; But this suction heat release in soil horizon is unbalanced, and the situation of this suction heat release can be used subordinate's formulae express:
Summer the heat release amount: Q
Release=Q
1' (1+1/cop)+Q
2+ Q
3
Recept the caloric winter: Q
Inhale=Q
1(1-1/EER)+Q
2+ Q
3
In the formula: Q
1'---the summer air-conditioning refrigeration duty,
Q
1---the winter air-conditioning thermic load,
Q
2---buried horizontal connection tube is along the journey heat loss,
Q
3---the heat release of circulating pump electrical power,
Visible (1+1/cop) is the coefficient greater than 1 in the formula, can (1-1/EER) is the coefficient less than 1.This shows that the heat that underground pipe discharges in the soil is greater than the heat that absorbs from soil, the imbalance of this suction heat release amount can cause the imbalance of air-conditioning system, and throughout the year month after month running also can cause the serious consequence of systemic breakdown.
The utility model content
The purpose of this utility model provides a kind ofly to be utilized air conditioning air exhaust to subdue to inhale the unbalanced device of heat release summer in underground pipe winter, this device can keeping system poised state, can subdue the waste heat that underground pipe discharges in the stratum by the operation of this device, safeguard the annual stable operation of heat pump.
The purpose of this utility model realizes by following technical proposals.
A kind ofly utilize air conditioning air exhaust to subdue summer in underground pipe winter to inhale the unbalanced device of heat release, comprise buried pipe heat exchange system, buried pipe heat exchange system links to each other with water knockout drum with water collector by pipeline respectively; Described water collector is leaded up to underground pipe water-circulating pump connecting pipeline and source pump and is joined, and another road connects the water-air heat exchanger by pipeline; Described water knockout drum is leaded up to pipeline and source pump and is joined, and another road connects the water-air heat exchanger by pipeline.
Wherein, the water-air heat exchanger is communicated with air-conditioning and construction by exhaust blower.
This device utilizes the air draft of summer air-conditioning building that lower air enthalpy principle is arranged, a good cooling source with respect to the underground pipe water circulation system, subdue underground pipe unnecessary heat extraction in the stratum by the air exhausting device device that utilizes summer air-conditioning building, being the new way of a comprehensive utilization of energy, also is the reliable facility of safeguarding heat pump stable operation.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, a kind ofly utilize air conditioning air exhaust to subdue summer in underground pipe winter to inhale the unbalanced device of heat release, comprise buried pipe heat exchange system 8, wherein: buried pipe heat exchange system 8 is respectively by pipeline G
2Link to each other with water knockout drum 5 with water collector 6; Described water collector 6 is leaded up to underground pipe water-circulating pump 4 connecting pipeline G
AlwaysJoin with source pump 7, another road is by pipeline G
1Connect water-air heat exchanger 3; Described water knockout drum 5 is leaded up to pipeline G
AlwaysJoin with source pump 7, another road is by pipeline G
1Connect water-air heat exchanger 3.
Wherein, water-air heat exchanger 3 is communicated with air-conditioning and construction 1 by exhaust blower 2.
Implementation is comparatively simple, as long as set up the water collecting and diversifying device of a water-air heat exchanger 3 and buried water in air draft place of air-conditioning and construction 1.Present domestic large public building all is provided with the facility of air-exhausting function, and temperature of outgoing air is near the air-conditioning indoor temperature, and enthalpy hangs down and is about 12.5Kcal/kg.If make 3-4 ℃ of again discharging of air exhaust heat exchange intensification, available enthalpy difference value is about 3.5Kcal/kg, and take the 1000m2 large public building as example, exhaust air rate reaches 30000m3/h usually, and available air draft cold reaches Q=G Δ i=1.24 * 30000 * 3.5=13 * 10
4Kcal/h.
From illustrating as seen, by the buried water wet well pipeline G of source pump 7
AlwaysA large amount of discharging heat of carrying are after water knockout drum 5 shuntings, and only some flow is through pipeline G
2Enter buried pipe heat exchange system 8, purpose makes pipeline G
2The caloric receptivity balance in buried water discharges heat and winter; Another part water yield of buried water shunting then enters water-air heat exchanger 3, by circulation after the exhaust system cooling in space.
The amount of heat that carries when the underground pipe water circulation system is worked summer enters in the soil, and certain discharge can be expressed as certain heat, i.e. Q=G Δ t, and circulation makes part discharge enter the underground pipe water system through the control shunting; Part then causes patent device, can be expressed as Q=G with formula
AlwaysΔ t=G
1Δ t+G
2If Δ t makes G
1Δ t equals the caloric receptivity in winter, and then the enthalpy in the soil horizon neither increases also and can not reduce, and reaches poised state.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model; can not assert that the specific embodiment of the present utility model only limits to this; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; can also make some simple deduction or replace, all should be considered as belonging to the protection domain that the utility model is determined by claims of submitting to.
