Abstract
The utility model discloses a cooling water system of a ground source heat pump. The cooling water system comprises a water collector, a water segregator, a plurality of buries pipes, a ground source heat pump unit, a circulating water pump and a closed cooling tower, wherein the buried pipes are arranged between the water collector and the water segregator; the ground source heat pump unit is connected between the water collector and the water segregator; the circulating water pump is connected in series with the ground source heat pump unit; and one end of the closed cooling tower is connected with the water collector, and the other end of the closed cooling tower is connected with the water segregator. The closed cooling tower is connected in parallel with the two ends of the ground source heat pump unit, so that heat exchange of the buried pipes is replenished and the cooling tower is started for dissipating heat when the water circulating temperature on a ground source side at refrigerating peak time; in winter, heat is exchanged by a buried pipe heat exchanger; in summer, heat is exchanged by the buried pipes; and the cooling tower is started for dissipating heat when the temperature of cooling water is too high. The cooling water system adjusts the balance between underground refrigerating amount and radiating amount, prevents the underground temperature from rising and ensures long-term stable and efficient operation of a heat exchanging system.
Description
Technical field
The utility model relates to a kind of earth-source hot-pump system, relates in particular to a kind of earth source heat pump cooling water system.
Background technology
See also Fig. 1, structural representation for the earth source heat pump cooling water system of prior art comprises water collector 1 ', water knockout drum 2 ', is connected in several ground pipe layings 3 ' between water collector 1 ' and the water knockout drum 2 ', the water circulating pump 5 ' that is connected in the earth source heat pump unit 4 ' between water collector 1 ' and the water knockout drum 2 ' and connects with earth source heat pump unit 4 '.
China Yangtze River Delta Area system summer refrigeration duty generally than winter thermic load big, and service time in summer is long, causes underground heat dissipation capacity much larger than the cold scattering amount, has therefore caused the imbalance of underground cold scattering amount and heat dissipation capacity, subsurface temperature rises, and has influenced system's long-term stability, operation efficiently.
The earth source heat pump cooling water system usually is subjected to the restriction in outdoor well-digging place, if outdoor lack of space often also can have influence on the heat radiation of cooling water system, thereby has influence on the effect of system.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art and a kind of earth source heat pump cooling water system is provided, it can regulate the balance of underground cold scattering amount and heat dissipation capacity, avoid the rising of subsurface temperature, guarantee ground pipe laying heat-exchange system long-term stability, operation efficiently.
The technical scheme that realizes above-mentioned purpose is: a kind of earth source heat pump cooling water system, comprise water collector, water knockout drum, be connected in several ground pipe layings between water collector and the water knockout drum, a water circulating pump that is connected in the earth source heat pump unit between water collector and the water knockout drum and connects with this earth source heat pump unit, wherein, also comprise a closed cooling tower, one end of this closed cooling tower links to each other with described water collector, and the other end links to each other with described water knockout drum.
The beneficial effects of the utility model are: the utility model is parallel to water circulating pump and earth source heat pump unit two ends with closed cooling tower, as replenishing of ground pipe laying heat exchange, when ground, refrigeration peak period source water loop temperature is too high, start the cooling tower heat radiation, utilize the ground heat exchanger heat exchange winter, summer is preferential utilizes ground pipe laying heat exchange, starts the cooling tower heat radiation under the too high situation of cooling water temperature.After cooling tower is parallel to the earth source heat pump cooling water system, can regulate balance, avoid the rising of subsurface temperature, guarantee heat-exchange system long-term stability, operation efficiently underground cold scattering amount and heat dissipation capacity.
Description of drawings
Fig. 1 is the structural representation of the earth source heat pump cooling water system of prior art;
Fig. 2 is the structural representation of earth source heat pump cooling water system of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
See also Fig. 2, there is shown a kind of earth source heat pump cooling water system of the present utility model, comprise water collector 1, water knockout drum 2, be connected in several ground pipe layings 6 between water collector 1 and the water knockout drum 2, a water circulating pump 4 that is connected in the earth source heat pump unit 3 between water collector 1 and the water knockout drum 2 and connects with this earth source heat pump unit 3, also comprise a closed cooling tower 5, one end of this closed cooling tower 5 with water collector 1 link to each other, the other end links to each other with water knockout drum 2, and promptly this closed cooling tower 5 is in parallel with ground pipe laying 6.
In the utility model, set up closed cooling tower 5, utilize winter ground pipe laying 6 to carry out heat exchange, then preferentially utilize summer ground pipe laying 6 to carry out heat exchange, starting the closed cooling tower of setting up 5 under the too high situation of cooling water temperature dispels the heat, as replenishing of ground pipe laying 6, regulate balance to underground cold scattering amount and heat dissipation capacity, avoided the rising of subsurface temperature.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
