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.
