Description
Technical field
The utility model relates to ground buried pipe of ground source heat pump heat-exchange system, particularly relates to one and automatically can realize thermally equilibrated ground buried pipe of ground source heat pump heat-exchange system.
Background technology
Along with carrying out in a deep going way of our national energy-saving environmental protection aspect work, central air-conditioning is the main body of architectural energy consumption, central air conditioner system energy-conservation and safe more and more important, as emerging energy conservation environmental protection air conditioner, ground-source heat pump central air-conditioning central authorities and governments at all levels widely popularize with under policy support, accepted by users gradually and apply, safety as the buried pipe heat exchange system of one of the most important part of ground-source heat pump central air-conditioning is the most important link of whole system safety, its whether safe safety directly determining whole ground source heat pump central air-conditioning system.
In traditional design and Practical Project, ground-source heat pump central air-conditioning cannot realize the automatic thermal balance of buried pipe heat exchange system, the cooling tower of system directly with system send water main pipe back to or water collecting and diversifying device is connected, the mode changing cooling is completely only had to realize, the automatic heat dissipation capacity of controlled cooling model tower and the operation of water pump thereof cannot be come according to the operating condition of reality, not only add the expense of water pump operation, also cannot carry out effectively can controlling safe adjustment to the heat of underground, cannot planned minimizing shotgun house be carried out to the heat in underground or suitably controllably increase discharge.In long-term operation, row's state of absorbing heat of this instability can cause the instability of underground temperature along with the change of weather, at northern area because cooling tower is at excessive auxiliary heat dissipation in summer, cause the heat accumulation energy shortage in soil in winter, and then affect the heating effect of equipment in winter, decrease the output of heat, thus affect heating, the long-term heat wretched insufficiency that in the past can cause in underground, temperature declines, and substantially increases unstability and the security of system; In southern area, because the heat radiation of cooling tower is not enough, system can be caused excessive in underground heat extraction, and the heat of discharge exceedes the heat absorbed from underground winter, and longtime running causes the rising of underground temperature, adds unstability and the security of system equally.
Utility model content
The technical problems to be solved in the utility model is: provide one automatically can realize thermally equilibrated ground buried pipe of ground source heat pump heat-exchange system.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
Ground buried pipe of ground source heat pump heat-exchange system, is characterized in that comprising earth source heat pump unit, the first temp probe, triple valve, cooling tower, cooling tower circulating pump and the second temp probe; Described earth source heat pump unit comprises evaporimeter and condenser; Described first temp probe is arranged on the buried water supply line of described condenser; The junction of buried water supply line and cooling tower back with water inlet line is provided with triple valve, described triple valve for controlling flow direction, when the first temp probe detects that water temperature in pipeline is higher than certain threshold value, trigger relay, controller controls triple valve, makes flow direction cooling tower; Described second temp probe is arranged on the water outlet pipeline of cooling tower, the VFC of energy cooling tower circulating pump according to the lower water temperature detected.
Preferably, also plate type heat exchanger is provided with between cooling tower back with water inlet line and cooling tower water outlet pipeline.Due to the structure that cooling tower is open, water is wherein often by pollutions such as the dust in environment, foreign material, algae, and the water that plate type heat exchanger makes to enter in the water of condenser and cooling tower is mutually isolated, avoids impurely pipe laying system.
The ground buried pipe of ground source heat pump heat-exchange system that the utility model provides achieves the automation regulating water (flow) direction and cooling effectiveness, solve because refrigeration is to underground heat extraction and to heat from soil heat absorption and cannot reach the difficult problem of the thermally equilibrated metering of nature and control, thus ensure that the thermal balance of underground temperature steadily in the long term, and can suitably adjust heat extraction and caloric receptivity according to actual needs, fundamentally ensure that the thermal balance of underground pipe system, ensure that the safety of the most important link of whole air-conditioning system.
