Abstract

The utility model provides a closed type cooling tower and buried pipe water-source heat pump type air-conditioning system, which comprises an indoor heat exchanger, two water-source heat pump air-conditioning units, a buried pipe and a closed type cooling tower. The two water-source heat pump air-conditioning units are connected in parallel with each other, wherein one side thereof is connected with the indoor heat exchanger to form a closed loop, and the other side thereof is connected with the buried pipe and the closed type cooling tower to form another closed loop. The buried pipe and the closed type cooling tower are connected in parallel with each other. The loop of the indoor heat exchanger is provided with an indoor circulating water pump. The loop of the buried pipe and the closed type cooling tower is provided with a buried pipe and cooling tower circulating water pump. According to the technical scheme of the utility model, when the cooling load of a buried pipe air-conditioning system is much larger than the heating load thereof, the unbalanced problem of the underground heat can be solved. Meanwhile, one part of the cooling load is realized by means of the closed type cooling power, so that the cooling power system and the buried pipe system can be in combined operation and are spare to each other. Therefore, two pipeline systems in a machine room are combined as one and the design is simplified. In addition, less equipment is adopted and the operation is facilitated.

Description

A kind of closed cooling tower-underground pipe water source heat pump air conditioning system
Technical field
The utility model relates to air-conditioning technical field, is specially a kind of closed cooling tower-underground pipe water source heat pump air conditioning system.
Background technology
In the most areas of south China, summer high heat and duration are of a specified duration, and winter, the cold time was short on the contrary, and people select air-conditioning system to alleviate the sense organ discomfort that environment brings to people conventionally.But at present, if winter, thermic load was far below summer during refrigeration duty in design, general design one platform independent open cooling tower and the refrigeration host computer system separately of adopting, water circulating pump is separate device also, and machine room just has independently two cover air-conditioner host systems, inconvenient operation like this, simultaneously can not be standby each other, cause water pump configuration also too many, machine room takes up an area larger, is unfavorable for energy-saving run.
Utility model content
The technical problem that the utility model solves is to provide a kind of closed cooling tower-underground pipe water source heat pump air conditioning system, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of closed cooling tower-underground pipe water source heat pump air conditioning system, comprise indoor heat exchanger, source heat-pump air conditioner group, underground pipe, closed cooling tower, described source heat-pump air conditioner group has two parallel connections, one side and indoor heat exchanger connect to form closed-loop path, opposite side connects underground pipe and closed cooling tower forms closed-loop path, the access in parallel with closed cooling tower of described underground pipe.
In the utility model, on the loop of described indoor heat exchanger, be provided with indoor circulation water pump, on described underground pipe and closed cooling tower loop, be provided with underground pipe and cooling-tower circulating water pump.
In the utility model, the compressor of described source heat-pump air conditioner group is semi-closed screw type compressor, in-built oil eliminator and oil strainer, and with fueling injection equipment, described fueling injection equipment is hydrojet expansion valve, to compression chamber hydrojet, for absorbing but lubricating oil of compression hot and cold, guarantee compressor normal operation.
In the utility model, the cold-producing medium adopting in described indoor heat exchanger closed-loop path is R134a, is furnished with economizer on closed-loop path.
In the utility model, described source pump changes in temperature switching is joined cross valve in taking and is carried out interior switching.
In the utility model, the valve body on each pipeline all adopts dish valve.
Beneficial effect: the utility model has solved in underground pipe air-conditioning system, refrigeration duty far surpasses the unbalanced problem of underground heat of bringing in thermic load situation, by closed cooling tower, share part refrigeration duty, and cooling tower systems and underground pipe system can cooperations, standby each other, machine room pipe-line system can unite two into one, simplified design, minimizing equipment, handled easily.
