Energy-saving air source heat pump unit

Abstract

The invention discloses an energy-saving air source heat pump unit which comprises a heat pump body, a rack, coil pipe supports and coil pipes. The heat pump body is installed on the rack, two transverse shafts are distributed symmetrically about the center line of a transverse plate, a sliding ring is slidably connected to a sliding rod, and the sliding rod and a reciprocating lead screw are installed on the front side and the rear side of the rack correspondingly. A lantern ring is in threaded connection with the reciprocating lead screw, the reciprocating lead screw is rotationally installed on the side of the rack, a motor shaft connected with a motor is installed on the rack, the motor shaft is connected with the reciprocating lead screw, and cleaning cotton is installed on the transverse shafts. According to the energy-saving air source heat pump unit, synchronous defrosting operation can be conducted on the coil pipes in two heat pumps in the unit, ascending-descending rolling defrosting of the cleaning cotton and hot air conveying for blowing drying are achieved at the same time through the same power, the possibility that a frost layer is frozen again after being melted iscompletely avoided, the overall heating effect of the heat pumps is improved, and the unit is more energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of air source heat pumps, in particular to an energy-saving air source heat pump unit. Background technique [0002] The air source heat pump unit refers to the use of multiple air source heat pumps in series by installing them on the rack, and uses the air source to heat water and other fluids. Compared with the transmission heating equipment, it is more energy-saving and environmentally friendly. When the air source heat pump unit When used in cold areas, the outer surface of the coil part in the coil bracket will be frosted accordingly, so the heat pump will have its own heating structure to melt the surface frost layer, so the existing air source heat pump unit The following problems exist: [0003] A single air source heat pump can defrost the coil through the operation of its internal heating elements, but when multiple heat pumps are combined to form a heat pump unit, using multiple heating elements ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an energy-saving air source heat pump unit to solve the above-mentioned background technology. A single air source heat pump can defrost the coil through the operation of its internal heating element, but when multiple heat pumps are combined When using a heat pump unit, using multiple heating elements to defrost at the same time will consume a lot of energy, resulting in a poor energy-saving effect. In the prior art, when the frost layer on the surface of the coil melts and drops, it falls The phenomenon of freezing will still occur on the top of the coil, and it is more likely to cause serious heat loss inside the coil when it accumulates under the coil, further reducing the heating effect
