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.
