Abstract

The utility model discloses a domestic small-sized solar heat pump water heater, which belongs to an industrial and civilian living apparatus and a small-sized solar energy water heater product mainly used for household aiming to ensuring the using of hot-water being provided day and night. The domestic small-sized solar heat pump water heater is mainly composed of an evaporator, a compressor, an expansion valve part and a water tank part. One side of the evaporator is provided with an axial flow blower fan, and the other side is provided with the expansion valve, a dry filter and the compressor. A high pressure controller and an electricity separating flange are connected with the compressor, and a refrigerant coil is arranged in the water tank part. A safety valve is matched with the water tank part, a water inlet and a water outlet are arranged on the water tank part, and the outer part of the water tank casing is provided with a heat insulation layer. The utility model has the advantages of high security, hot-water capable of being provided day and night, efficient energy-saving, save electricity, easy use and installation, environment protection and no contamination.

Description

The household small-sized solar Teat pump boiler

One, technical field

The utility model belongs to industry life device, is mainly used in the product of the small-sized solar water heater of family.

Two, background technology

In the society various solar water heaters are arranged now, the thermal efficiency is lower often wherein weak point, and it is bigger influenced by weather conditions, usually can not guarantee to provide hot water round the clock, and perhaps equipment investment cost is higher.

Three, summary of the invention

According to above existing problems, the purpose of this utility model provides a kind of suitable household small-sized solar Teat pump boiler, solves to ensure and can provide hot water round the clock, and is cheap.It mainly partly is made up of with water pot parts such as evaporimeter, compressor, expansion valves.In evaporimeter one side axial flow blower is housed, opposite side is equipped with expansion valve, device for drying and filtering and compressor, the dual pressure controller that has that is connected with compressor reaches every the electrical method orchid, in the water pot part, refrigerant coil pipe one cover is housed, the safety valve that has that partly matches and install with water pot, be shaped on water inlet pipe mouth and effluent pipe mouth part, and outside the water pot housing, heat-insulation layer be housed.

Main beneficial effect of the present utility model is safe, because of having installed every the electrical method orchid specially, for example in very accidental electric leakage, can not enter in the water yet, can stop the generation of security incident on 100% ground by copper pipe, in addition can energy-efficient power saving, used state-of-the-art heat pump techniques, the heat that the sun is gratuitously given in the air is entered in the water by the refrigerant circulation, can save 70% power consumption than the hot device of common electrical man, suitable ordinary people promotes the use of; Easy for installation in addition, floor space is less relatively, heat supply water round the clock, and compliance with environmental protection requirements does not produce any pollution.

Four, description of drawings

As figure is structural representation of the present utility model.

Among the figure 1, water inlet pipe mouth, 2, water pot, 3, effluent pipe mouth, 4, refrigerant coil pipe, 5, every the electrical method orchid, 6, the dry filter pipe, 7, compressor, 8, expansion valve, 9, dual pressure controller, 10, screen pack, 11, three-way air valve, 12, every air blade, 13, rotary handle, 14, evaporimeter, 15, axial flow blower, 16, heat-insulation layer, 17, safety valve

Five, embodiment

As seen from the figure, axial flow blower 15 is housed, expansion valve 8, device for drying and filtering 6 and compressor 7 is installed at the opposite side of evaporimeter 14 in evaporimeter 14 1 sides, compressor 7 be connected dual pressure controller 9 is arranged and every electrical method orchid 5; Above of the present utility model, be the top of evaporimeter 14 screen pack 10, three-way air valve 11 are installed, every air blade 12 and rotary handle 13, water pot 2 parts are installed below evaporimeter 14, refrigerant coil pipe 4 one covers are housed in its water pot 2, water pot partly matches safety valve 17 is installed therewith, and be shaped on water inlet pipe mouth 1 and effluent pipe mouth 3, and outside water pot 2 housings, heat-insulation layer 16 is housed, be not subjected to ectocine so that ensure the hot water temperature's value in the water pot.Practical work process of the present utility model is like this: 1, refrigerant flow path: the gas coolant of the HTHP that comes out from compressor 7 is through entering water tank refrigerant coil pipe 4 every electrical method orchid 5, after the abundant heat exchange of water in the water tank, become cryogenic high pressure liquid, enter expansion valve 8 decompressions behind the drying filter 6, become low-pressure liquid, enter evaporimeter 14 then and flash to gaseous state, absorb airborne heat by axial flow blower 15 simultaneously, circulate once more from the evaporimeter back pressure compressor that comes out then.By this circulation, airborne heat is released in the water that absorbs water tank, makes water at low temperature become high-temperature water, thereby provides the domestic hot-water to family, does not have the sun also can heat.

2, current journey: cold water enters water pot through water inlet pipe mouth 1, and heating is after effluent pipe mouth 3 offers family uses, and water pot partly is equipped with safety relief valve 17, can pressure release when the jar internal pressure is too high, guarantee safety.

3, air flow process: normal temperature air enters evaporimeter 14 through filter screen 10, after giving refrigerant exchange heat, discharge by axial flow blower 15, three-way air valve 11, wherein summer is during hot weather, can forward handle 13 to the A position, it is indoor that the cold wind transverse row is gone into, and gives room temperature lowering, when indoor when not needing cold wind, can forward rotary handle 13 to the B position, send discharge outdoor by blast pipe in cold wind.Safe and convenient to use energy-conservation again.
