Solar-energy evaporator special for air source heat pump

Abstract

The invention relates to the technical field of evaporators, in particular to a solar-energy evaporator special for an air source heat pump. The solar-energy evaporator comprises a transparent shell of a cuboid plate structure and is characterized in that the interior of the shell is divided into an upper cavity and a lower cavity; the upper cavity is filled with a thermal-insulation foam layer, multiple wave-shaped bent first collector pipes are embedded into the foam layer, second collector pipes vertical to the bottom surface of the shell are arranged at the curvature circle positions of the bent parts of the first collector pipes, and the second collector pipes and the first collector pipes are connected through a plurality of third collector pipes; the left ends of the first collectorpipes are jointly connected with a first left main pipe, and the right ends of the first collector pipes are jointly connected with a first right main pipe; a plurality of copper pipes for absorbingair heat are arranged inside the lower cavity, and a plurality of collector pieces vertically sleeve the copper pipes. The solar-energy evaporator is high in heat efficiency, convenient to use, good in practical value and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of evaporators, in particular to a special solar evaporator for air source heat pumps. Background technique [0002] At present, most of the existing evaporators use air source heat pumps to provide heat sources. However, the pure air source heat pump still has the problem of insufficient thermal efficiency in the specific use process. At present, some evaporators use solar energy as a heat source, but the thermal efficiency still has the same problem, which is not conducive to the full utilization of thermal energy resources. [0003] Therefore, based on the above, the present invention provides a special solar evaporator for air source heat pumps. By rationally improving and designing the structure of the evaporator, the evaporator can be well combined with solar energy and air heat sources, fully and rationally utilizing renewable resources, and improving The thermal efficiency of the evaporator is used...
