Abstract

The invention provides a ground source central air conditioning system which comprises an indoor radiating device, a user circulating pump, a screw unit, a water source circulating pump and a same-well circulating ground heat energy collecting device. The same-well circulating ground heat energy collecting device is connected with a water inlet end of the screw unit through a water supply pipe. A water outlet end of the screw unit is connected with the indoor radiating device through a water supply pipe. A water returning end of the indoor radiating device is connected with the screw unit through a water returning pipe and the user circulating pump. A water returning end of the screw unit is connected with the water returning pipe of the same-well circulating ground heat energy collecting device through a water returning pipe and the water source circulating pump. The ground source central air conditioning system is small in occupied space, underground water is not consumed, operation is reliable and safe, cost is low, the using range is wide, and heat energy collecting amount is large.

Description

Source, ground central air conditioner system

Technical field

The present invention relates to source, a kind of ground central air conditioner system, belong to air-conditioning system technical field.

Background technology

There is following drawback in source, existing ground central air conditioner system: 1. occupied ground is large; 2. cost is high; 3. long-term use can not be recharged completely and be caused level of ground water to decline; 4. in using, produce and move sand, long-term use causes geology to subside; 5. conditional request is harsh to external world, when during as employing cooling tower and air-source heating, winter temperature is extremely low, even can not move; 6. energy acquisition efficiency is low, can not meet needs.

Summary of the invention

For the problems referred to above, the invention provides source, a kind of novel ground central air conditioner system.

Technical scheme of the present invention: source, ground central air conditioner system, comprise indoor radiating device, user's circulating pump, screw rod unit, water source circulating pump and with well heat energy harvester cyclically, with well cyclically heat energy harvester by feed pipe, be connected with screw rod unit water inlet end, the water side of screw rod unit is connected with indoor radiating device by feed pipe, the backwater end of indoor radiating device is connected with screw rod unit by return pipe, user's circulating pump, the backwater end of screw rod unit by return pipe, water source circulating pump and same well cyclically the return pipe of heat energy harvester be connected.

Described same well is heat energy harvester cyclically, comprise the borehole wall and well casing, well casing is placed in borehole wall inside, the bottom of well casing is provided with the sediment tube of taper, sidewall in well casing bottom is provided with filter pipe, in the chamber forming, is full of quartz sand between the borehole wall and well casing, return pipe above concrete cushion and with the above-mentioned borehole wall and well casing between the chamber that forms be communicated with, feed pipe is placed in the inside of well casing, and the bottom of feed pipe is provided with immersible pump; Be positioned at the medium position place of whole well casing, some mozzles in the chamber forming, have been uniformly distributed circumferentially between the borehole wall and well casing, the upper and lower of mozzle is respectively equipped with rubber division board, two rubber division boards are divided into three sections by the chamber forming between the borehole wall and well casing, and wherein epimere and hypomere are as heat exchange zone.

Beneficial effect of the present invention: the present invention utilizes source, ground to substitute traditional cooling tower power-saving technology, the present invention not only can be applicable in central heating refrigeration system, but also can be used for big-and-middle-sized building energy conservation reduction of discharging or public building energy reduction of discharging, its concrete manifestation is as follows:

1 takes up an area less, only needs beat a glance production wells, can be placed on road, and in greenbelt etc., outward appearance is only seen a standard well lid;

The 2 environment friendly and pollution-free geologic structures of not destroying, this device only gathers the energy in underground water, does not consume underground water;

3 is safe and reliable to operation, in service without HTHP, moves without desilting for a long time, and totally-enclosed pipe-line system is corrosion-free;

4 costs are low, and a collecting unit can replace current one 4 wells for many times patterns, and cost reduces 40% relatively;

5 scopes of application are wide, in the area that underground water is poor, all can apply this device;

6 one covering devices can provide the energy of 700KW, can supply 8000m ²building refrigeration and heating.
