Multi-energy complementary air source heat pump

Abstract

The invention discloses a multi-energy complementary air source heat pump which comprises an assembled skeleton, condenser fins vertically arranged inside the assembled skeleton, air inlets and air outlets. The air inlets and the air outlets are arranged in the top or side walls of the assembled skeleton, the assembled skeleton is of a frame structure, each surface is covered with a heat insulation board, the condenser fins divide the interior of the assembled skeleton into two parts including a heat chamber and a cold discharge chamber, the heat chamber is internally provided with heat-supplementing heat sink fins, the cold discharge chamber is internally provided with a power box, a centrifugal fan, a heat exchanger, a compressor, a gas-liquid separator and a connecting pipe, and the power box is electrically connected with the compressor, the centrifugal fan, the heat exchanger and the gas-liquid separator. The multi-energy complementary air source heat pump is additionally providedwith a shell heat preservation box and a heat-supplementing heat sink, the working environment of the air source heat pump can be changed, the energy-efficiency ratio of the air source heat pump canbe improved under the low temperature state, the aim of better reducing fossil energy consumption is achieved, and the wide applicability is achieved.

Description

technical field [0001] The invention relates to the technical field of air source heat pumps, in particular to a multi-energy complementary air source heat pump. Background technique [0002] At present, air source heat pumps have been widely used in many areas of our country. In the southern region, the outdoor temperature is generally not lower than minus 5°C in winter, and the indoor heat demand is not large. Air source heat pumps work well and have high energy efficiency. In the northern region, the outdoor temperature is very low in winter. As far as the air source heat pumps currently on the market are concerned, the heating capacity of the system drops rapidly as the outdoor ambient temperature drops. When the outdoor temperature is very low, the heating capacity of the system cannot even meet the heating requirements. demand, causing the system to fail to function properly.

Problems solved by technology

In the northern region, the outdoor temperature is very low in winter. As far as the air source heat pumps currently on the market are concerned, the heating capacity of the system drops rapidly as the outdoor ambient temperature drops. When the outdoor temperature is very low, the heating capacity of the system cannot even meet the heating requirements. requirements, causing the system to fail to function properly

[0003] In addition, the drop of outdoor temperature in winter will also reduce the efficiency of the compressor. When the outdoor temperature drops, the evaporating temperature and evaporating pressure will decrease, while the condensing pressure will not change much, which will inevitably lead to an increase in the compression ratio of the compressor and a great decrease in heating efficiency. At the same time, the increase of the compression ratio will cause the discharge temperature of the compressor to rise continuously, the power consumption of the compressor will increase, and the efficiency will decrease. Long-term high discharge temperature will also cause damage to the compressor and seriously affect the service life of the compressor.
