Heat pump air conditioner of air source, solar, water source

Abstract

The invention is an air-source solar water-source heat pump air- conditioning system, comprising two water-source heat pumps, where the two water-source heat pump are interconnected through the pipeline equipped with circulating pump to compose a first-stage air source heat pump and a second-stage artificial water source heat pump, the output end of the second-stage artificial water source heat pump is connected through the above pipeline with the air-conditioning terminal equipment, and the first-stage air source heat pump is connected through the above pipeline with the air source heat exchanger. And it connects two water-source heat pumps in series, configures an air-source heat exchanger for the fore-stage heat pump to obtain low-temperature heat energy in the air, and makes them compose a heat pump air-conditioning system with a first-stage air-source heat pump and a second-stage artificial water-source heat pump, thus effectively solving many problems caused by the current water source heat pump air-conditioner of needing to bury soil heat exchanger and drill a water well and making the heat pump air-conditioner suitable to safely, reliably and in high efficiency supply heat in the environment of outdoor air temperature below -7 deg.C.

Description

technical field [0001] The invention relates to a water source heat pump air conditioner, in particular to an air source solar water source heat pump air conditioner. Background technique [0002] Water source heat pump air conditioners are currently recognized as energy-saving and efficient air-conditioning equipment. However, the water source heat pump needs an external low-temperature water source to absorb the heat of the low-temperature water source, and transfer the low-temperature heat to the high-temperature heating circulating water for indoor heating. At present, water sources for water source heat pumps are mainly obtained by burying soil heat exchangers and drilling groundwater wells. However, burying soil heat exchangers requires a large area of ​​land, and the construction is difficult and expensive.

Problems solved by technology

At present, water sources for water source heat pumps are mainly obtained by burying soil heat exchangers and drilling groundwater wells. However, burying soil heat exchangers requires a large area of ​​land, and the construction is difficult and expensive.

The method of drilling groundwater wells to provide water sources for water source heat pumps, although the project cost is relatively low, has the problem of difficult recharge of well water, and because the groundwater contacts with the air through the outlet wells and recharge wells, the ferrous iron in the water and Oxygen molecules in the air undergo a chemical reaction and turn into ferric iron, turning the groundwater into reddish brown, causing groundwater pollution, so it is strictly restricted by the relevant departments

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

However, the current air-cooled hot and cold water air conditioners can only be used for normal heating operation in an environment where the outdoor temperature is above -7°C, and cannot be widely used in cold regions.
