Low-environmental-temperature type air source heat pump

Abstract

The invention discloses a low-environmental-temperature type air source heat pump. The low-environmental-temperature type air source heat pump comprises a box body, a dustproof plate, an evaporator and a filtering pipe, wherein an air inlet is formed in the top end of the box body, and a heat dissipating plate is mounted on the surface of the box body; the side edge of the dustproof plate is connected to the side edge of the air inlet; two ends of the evaporator are mounted at the upper end of the inner wall of the box body; a compressor is mounted in the middle of the inner wall of the box body, and the bottom part of the compressor is connected to an exchanger; heating copper tubes are mounted in the exchanger, and a hot water port and a cold water port are correspondingly formed in twoends of the exchanger; the filtering pipe is mounted on the outer wall of the box body; and one end of the filtering pipe is connected to the cold water port. According to the low-environmental-temperature type air source heat pump, the heat dissipating plate, so that the problem that heat is hardly dissipated when equipment runs; and water can be filtered through a filtering element in the filtering pipe, so that the problem that the water cannot be filtered before being heated and easily leads to dirt in the exchanger can be solved.

Description

technical field [0001] The invention relates to the technical field of air source heat pumps, in particular to an air source heat pump with low ambient temperature. Background technique [0002] The air source heat pump is an energy-saving device that uses high-level energy to make heat flow from low-level heat source air to high-level heat source. It is a form of heat pump. As the name implies, a heat pump is like a pump, which can convert low-level thermal energy that cannot be directly used (such as the heat contained in air, soil, and water) into high-level thermal energy that can be used, thereby saving some high-level energy (such as coal, gas, oil, etc.) , electricity, etc.) purpose. [0003] However, the existing air source heat pump cannot filter the water before heating it, which makes it easy to leave dirt in the exchanger, and the heat generated by the equipment during operation is difficult to discharge. In view of the above problems, it is urgent to carry ou...
