Central Air Conditioning

1, the traditional central air conditioning with air source heat pump (air-cooled unit) + auxiliary electric

heating and water-cooled chiller + boiler two forms. Air-source heat pump (air-cooled unit) and water-

cooled chillers are cooling the room to the outdoor air emissions, by the outdoor temperature factors too

much, the cooling capacity with the outdoor air temperature decreases, especially at high temperatures

Wet areas, the unit cooling performance is extremely unstable, inefficient, and sometimes even can not

work.

In the heating, the air source heat pump when the outdoor temperature dropped below zero when the

need to add auxiliary heating device, power consumption, efficiency is very low; and water-cooled chiller +

boiler this form of air conditioning, Boilers or coal, oil boilers, pollution is serious, running expensive.

2, ground source heat pump central air conditioning: ground source heat pump central air conditioning is

divided into water source heat pump and soil heat exchanger ground source heat pump two forms

2.1 water source heat pump central air conditioning water source heat pump concept, principles and

classification

2.1.1, water source heat pump concept water source heat pump Technology is a low temperature energy

resource that utilizes the surface of the earth or shallow water (such as groundwater, rivers and lakes), or

artificial reclaimed water (industrial waste water, geothermal tail water, etc.), using heat pump principle,

through a small amount of high power input , To achieve low heat to high heat transfer, both heating and

cooling can be efficient, environmentally friendly, energy-efficient air conditioning system.

2.1.2, the principle of water source heat pump on the surface of the shallow water (usually within 1000

meters), like groundwater, surface rivers, lakes and oceans, absorb the sun into the Earth's considerable

radiation energy, and the water temperature is generally very stable. Water source heat pump technology

works is: in the summer will be the heat in the building "take" out, released to the water body, because the

water temperature is low, so you can effectively take away the heat in order to achieve the summer to the

building indoor cooling purposes; The winter, it is through the water source heat pump unit, from the water

"extraction" heat, sent to the building heating. Usually water source heat pump consumes 1kW of energy,

the user can get more than 4kW of heat or cooling.

2.1.3, water source heat pump classification When the use of objects are water and formation (aquifer)

storage, and are water as a heat pump unit heat source, can be classified as water source heat pump

system. Water source heat pump can be divided into underground water source heat pump and surface

water source heat pump. Groundwater heat pump system, which is commonly referred to as deep well

recharge water source heat pump system.

Through the construction of pumping wells to extract the groundwater, through the second heat transfer

or directly to the water source heat pump unit, after the extraction of heat or heat release, by the recharge

wells poured into the ground. Surface water heat pump system. Through the direct extraction or indirect

heat transfer, the use of including rivers, rivers, lakes, reservoir water and sea water as a heat pump heat

source.
