Description

The two thermal source evaporimeters of photo-thermal coupling

Technical field

The present invention relates to a kind of pair of thermal source evaporimeter, be specifically related to a kind of evaporimeter that can utilize simultaneously heat energy in solar energy and the air.This evaporimeter can absorb in solar energy and the air heat energy as thermal source simultaneously at fine day, for air-conditioning and hot water machine provide thermal source; Can absorb separately heat energy in the air at rainy weather.

Project background

Net for air-source heat pump units winter frost removing problem is a large technical barrier.Particularly on Hunan, Guizhou and other places, although winter temperature is not too low, air humidity is very large, and source pump causes heating efficiency sharply to reduce because of frequent defrosting.And these local solar energy resourceses are abundant, can't satisfy hot water or heating demand in winter only according to solar energy.If can take full advantage of these two kinds of heat energy as the thermal source of source pump, will effectively promote the efficiency that heats in source pump winter.

Summary of the invention

The purpose of this utility model is to propose a kind of New Evaporator, can absorb simultaneously heat energy and solar energy in the air, reduce defrosting time to reduce source pump defrosting number of times, and improve evaporating temperature, thereby improve the heat pump scheme of the unit winter heating coefficient of performance.

The two thermal source evaporimeters of a kind of photo-thermal coupling, be comprised of copper pipe and fin, copper pipe curves a plurality of U-shaped portion parts and wears fin and mistake, and the copper pipe of this evaporimeter is divided into conduction oil copper pipe and cold-producing medium copper pipe, the conduction oil copper pipe is positioned at the central area of fin, and the cold-producing medium copper pipe is respectively in around the conduction oil copper pipe; Conduction oil copper pipe and outside heat conduction oil circulating pump and solar thermal collector form a loop, and conduction oil absorbs solar heat energy in solar thermal collector, conduct heats by the driving of heat conduction oil circulating pump to two thermal source evaporimeters; The cold-producing medium copper pipe with form a loop with external heat pump assembly refrigeration system, from two thermal source evaporimeters, absorb heat; The fin area of evaporimeter is greater than the fin area of common evaporimeter.

Radiating fin is characterised in that conduction oil copper pipe and cold-producing medium copper pipe is linked together, and when source pump heats heat is conducted to the cold-producing medium copper pipe from the conduction oil copper pipe, thereby improves the source pump evaporating temperature; During defrosting, fin can absorb heat and the airborne heat in the conduction oil copper pipe simultaneously, thereby accelerates defrost speed.In without the sun, because the fin area of the more common evaporimeter of area of radiating fin wants large, the coefficient of heat transfer is higher, therefore can absorb more heats from air.

The specific embodiment

Now by reference to the accompanying drawings the utility model is elaborated:

Describe referring to accompanying drawing 1, accompanying drawing 2, on the basis of common finned heat exchanger, copper pipe is divided into two groups, be respectively conduction oil copper pipe 1 and cold-producing medium copper pipe 2. wherein conduction oil copper pipe 1 be positioned at the central area of fin 3, cold-producing medium copper pipe 2 is respectively in around the conduction oil copper pipe 1.Again conduction oil copper pipe 1 and heat conduction oil circulating pump 4, solar thermal collector 5 are connected into a loop in addition, heat conduction oil circulating pump 4 drives conduction oil and circulates between solar thermal collector 5 and two thermal source evaporimeter.During two thermal source evaporator operation, cold-producing medium copper pipe 2 and fin 3 are except absorbing airborne heat, conduction oil copper pipe 1 is directly passed to cold-producing medium copper pipe 2 and inner cold-producing medium thereof by the aluminium fin with the heat that obtains in the solar thermal collector 5, thereby increase the evaporating temperature of source pump, promote heating efficiency.

During two thermal source evaporimeter defrost, fin 3 can absorb the solar heat in the conduction oil copper pipe 1 simultaneously, and the source pump in the cold-producing medium copper pipe 2 defrosting heat, thereby accelerates defrost speed, reduces defrost running time.This pair of thermal source evaporimeter can also be applied to air source hot pump water heater except being used for air-conditioner.In air source hot pump water heater, because this evaporimeter can absorb solar energy, therefore at the abundant weather of solar energy, can also provide hot water by solar energy separately.
