Embodiment 1

[0012] After extracting the 9-11 ℃ low-temperature water in the abandoned well with a deep water pump, it is introduced into one side of the plate heat exchanger through the heating circulation pipe of the building’s winter heating, and the low-temperature water in the abandoned mine passes through the plate heat exchanger and the other side The circulating chilled water after the extension coil takes away the heat from the plate heat exchanger and sends it to the user pipeline. The circulating water in the extension coil enters the circulation pump through the secondary pipe network and is pumped into the plate heat exchanger to continue circulating. The net is to refill the mine water that has absorbed heat into the mine under the action of the deep well pump after passing through the plate heat exchanger.

[0013] The plate heat exchanger is formed by stacking corrugated metal sheets. Rectangular passages are formed between various metal sheets, and heat is exchanged through...

Embodiment 2

[0015] After extracting the 9-11°C low-temperature water in the abandoned well, use the pump to circulate the low-temperature mine water through one side of the plate heat exchanger as refrigerant water, absorb the heat of the circulating frozen water on the other side of the heat exchanger, and turn the low-temperature (15 -18℃) chilled water is transported to the indoor extension coil through pipelines, and the indoor extension coil works to achieve the purpose of cooling. The refrigerant water that has absorbed the heat is returned to the underground mine through the pipeline.

Embodiment 3

[0017] Use the heating circulation pipes of the existing buildings for heating in winter, connect the plate heat exchanger, the circulating water pump, and use the original heating pipes in the park as the water supply and return pipes for the external network pipes. The increased heat exchangers, circulating water pumps and other equipment can be fully utilized as heating equipment in winter.

[0018] The existing set of equipment in the park has the above-mentioned remarkable characteristics. In summer, the equipment is used to cool the existing office building by taking advantage of the low temperature of mine water. In winter, the heat exchange station in the park provides high-temperature hot water at 90-75°C, and the building is heated through this device.

Abstract

The invention relates to an energy saving and environment-friendly type air conditioning system. The air conditioning system is characterized in that after low-temperature water in an abandoned mine well through a deep-water pump, the water is guided into one side of a planar heat exchanger through a heating circulating pipeline of a building for winter heat supplying, after the low-temperature water in the abandoned mine well passes the planar heat exchanger and a branch coil on the other side, the circulating chilled water brings heat of the planar heat exchanger to deliver to users' pipelines, the circulating water in the branch coil enters a circulation pump through a secondary pipe network before being pumped into the planar heat exchanger to circulate continuously, and a primary pipe network is used for injecting mine water, whose heat is absorbed completely through the planar heat exchanger, into the mine well under the effect of the deep well pump. A large amount of underground water produced in the abandoned mine well in a park serves as the air-conditioning cooling circulating water, annual energy saving amount can be 4400000KWh, equivalent to 1570.8 tons of standard coal. The utilization rate of water in the abandoned mine well is improved, energy saving and emission reduction can be implemented, and the environment can be protected.

Description

technical field [0001] The invention relates to an energy-saving and environment-friendly air-conditioning system, which is an air-conditioning system for refrigeration and heating in a park. Background technique [0002] Existing central air conditioners mainly use screw-type water-cooled units. The main working method is to use water as a refrigerant cycle. First, water is used to absorb the energy generated by the central air-conditioning unit to reduce the temperature of the water, and then the water is pumped into the house. Fan coil unit for cooling. [0003] It has the following disadvantages: 1. The one-time investment is large. 2. High power consumption. 3. Each building must build an air-conditioning machine room. 4. It is necessary to transform the electricity load of each building and increase investment. Contents of the invention [0004] The purpose of the present invention is to provide an energy-saving and environment-friendly air-conditioning system, w...
