Abstract

The invention discloses an environment-friendly energy-saving air source heat pump unit with a self-cleaning function, and belongs to the energy-saving hot water supply field. The unit comprises a heat pump body and a high-pressure pump. An evaporator and a cleaning device are arranged in an upper end of the heat pump body. The cleaning device is a pipeline provided with a plurality of nozzles, the cleaning device is located on one side of the evaporator, the nozzles face towards the evaporator, one end of the cleaning device is connected with the high-pressure pump, filter screens are arranged on two sides of an upper end of the heat pump body, and a dustproof shutter is arranged outside the filter screens and is connected with the heat pump body through hinges. The dustproof shutter andthe filter screens can prevent large-particle grass leaves and dust from being adsorbed to the surface of the evaporator, the filter screens can be detached for regular cleaning, a ventilation quantity is guaranteed, the cleaning device can guarantee that a heat exchange surface of the evaporator is clean, and therefore heat exchange efficiency can be ensured not to be reduced.

Description

technical field [0001] The invention relates to the field of energy-saving hot water supply, in particular to an environment-friendly and energy-saving air source heat pump unit with self-cleaning function. Background technique [0002] With the popularization of coal-to-electricity projects, energy-saving air source heat pump technology has become more and more widely used; however, with the popularization and application of air source heat pump units, the energy efficiency of units with a long service life has declined, and a large part of the reason is that the surface of the evaporator Covered and wrapped by leaves, dust, iron filings, flying paint, etc., it will affect the heat exchange efficiency of the air source heat pump evaporator, cause the heat absorption capacity to decay and reduce the overall COP value of the heat pump; in addition, the accumulation of such impurities is also easy to cause flammable Hidden dangers affect safe and stable operation.
