Air source water source heat pump air-conditioner

Abstract

The invention relates to an air source water source heat pump air conditioner, which comprises: a water source heat pump whose output via tube is connected to the end of air conditioner; and a water source via the tube with cycle water pump is connected to the output of air source water source heat exchanger. Wherein, the input of said heat exchanger via the tube with compressor and expansion valve is connected to the air source heat exchanger. The invention arranges the first air source heat pump on the water source heat pump to attain low-temperature energy of air, and via air source heat exchanger to supply right heat source water to the second artificial water source heat pump. Compared to present product, it can avoid the problems caused by embedding heat exchange tube, to realize effective operation in -7Deg. C to -45Deg. C.

Description

technical field [0001] The invention relates to a water source heat pump air conditioner, in particular to an air source water source heat pump air conditioner. Background technique [0002] Water source heat pump air conditioners are currently recognized as highly efficient and energy-saving air conditioners. However, water source heat pump air conditioners need an external low-temperature water source during operation. At present, the low-temperature water source of water source heat pumps is mainly obtained by burying soil heat exchange pipes and drilling groundwater wells. However, burying soil heat exchange pipes requires a large area of ​​land and is difficult to construct. Big, expensive project. Using groundwater wells to obtain low-temperature water sources, although the project cost is lower than that of burying soil heat exchange pipes, there is a problem of difficulty in recharging the well water, and after the groundwater is in contact with the air through the ...

However, water source heat pump air conditioners need an external low-temperature water source during operation. At present, the low-temperature water source of water source heat pumps is mainly obtained by burying soil heat exchange pipes and drilling groundwater wells. However, burying soil heat exchange pipes requires a large area of ​​land and is difficult to construct. Big and expensive

Using groundwater wells to obtain low-temperature water sources, although the project cost is lower than that of burying soil heat exchange pipes, there is a problem of difficulty in recharging the well water, and after the groundwater is in contact with the air through the outlet wells and recharge wells, the ferrous iron in the water and the air Oxygen molecules undergo a chemical reaction and turn into ferric iron, causing the recharged well water to turn reddish brown, causing groundwater pollution, so it is strictly restricted by relevant departments

Due to the above reasons, the popularization of water source heat pump air conditioners is greatly restricted.
