Abstract

The utility model belongs to refrigeration equipment, mainly relating to an absorption and dispersion refrigerator without a compressor. The prior art adopts resistance wires as a heat source with slow heating speed, many heat losses and poor safety performance. The heating element of a generator of the utility model is arranged in a barrel-shaped surface formed by an inner tube and an outer tube, the heating element is formed by a PTC element and a metal casing, the heating element utilizes the constant temperature characteristic and other favorable performances of the PTC element, thus the absorption and dispersion refrigerator has high heating speed, few heat losses, long service life and low cost.

Description

Refrigerator without compressor

The utility model belongs to refrigeration plant, relates generally to compressor-free absorption-diffusion type refrigerator.

At present, the refrigerator of family's use both at home and abroad mostly is that compressor is arranged, i.e. the steam compression type refrigerator.This refrigerator power consumption is many, the cost height, and complex structure as cold-producing medium, easily causes environmental pollution with fluorine Lyons, and service life is short; Because compressor operating forms noise, influences people's rest and health.Now existing solar energy type, towards the refrigerator of magnetic-type, thermocouple peer type, just be used in the laboratory, do not form the suitability for industrialized production ability.Recently, a kind of absorption-diffusion type refrigerator is arranged, as thermal source, though problems such as noiseless and environmental pollutions, firing rate is slow with resistance wire, and heat loss is too big, and poor safety performance is bad as heater, needs whole replacing heater, and waste is serious.In heating process, the resistance wire heating tube is that line contacts with the generator outer tube wall, thereby the heat of most of heating face is wasted.With SANYO GS company 50 liter refrigerating boxes is example, the about 90W of its power consumption.

The purpose of this utility model provides that a kind of firing rate is fast, and the life-span is long, and is safe and reliable, can make full use of heat, the absorption-diffusion type refrigerator that cost is low.

The utility model is by heater, siphon pipe, condenser, evaporimeter, absorber, surge drum and connect in the refrigeration system of forming with pipeline, manage in heater is placed and formed barrel-shaped of outer tube among.

Its heater is to use the posistor device, and promptly the PTC element is as thermal source; Heater is to be made of PTC element and metal shell.

The utility model compared with prior art has:

1, simple in structure, noiseless and environmental pollution; Adopt new generator architecture, heater has been placed between the inner and outer pipe, can make full use of heat, reduced heat-energy losses.

2, adopted new heater element, the life-span is long, but and automatic constant-temperature, keep optimal occurrence temperature.Firing rate is fast, and security performance is good, if the PTC element is bad, only changes the PTC element, wastes less.

3, be example with SANYO GS company 50 liter refrigerating boxes equally, as adopt new structure and heater element, its power consumption is 60W only, economize on electricity about 30%.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model structural principle schematic diagram.

Fig. 2 is the structure chart of the utility model calandria.

Pressing the refrigerator of the principle made of Fig. 1 and Fig. 2, is most preferred embodiment of the present utility model.

In Fig. 1, rise by the ammoniacal liquor vaporization that is subjected to heater 2 heating in interior pipe 1 and the outer tube 3, rise to condenser 6 through siphon pipe 4 and pipeline 5, ammonia steam is met the cold liquefied ammonia that becomes, liquefied ammonia utilizes in the potential energy inflow evaporator 7 and contacts with hydrogen, spreads in hydrogen, forms evaporation process; Ammonia evaporates back and hydrogen synthetic ammonia hydrogen mixed gas, drops to absorber 8 along pipeline 5, and the distilled water in the absorber becomes ammoniacal liquor after absorbing ammonia, enters surge drum 9, and then enters interior pipe 1 and outer tube 3, forms a heat cycles overall process.Because inner and outer pipe is enclosed in heater 2 wherein, so can make full use of heat, reaches best vaporization effect.

In Fig. 2, the 10th, PTC element, the 11st, metal shell, the 12nd, power supply lead wire.PTC element 10 can be cuboid or cylindrical; Metal shell 11 can be used aluminium alloy, steel plate, and copper coin or other sheet of metallic material are made.Power supply lead wire 12 is the positive and negative electrode lead-in wire of PTC element 10.

Claims

1, a kind of compressor-free refrigerator comprises: heater 2, interior pipe 1 and outer tube 3 and siphon pipe 4, condenser 6, evaporimeter 7, absorber 8, surge drum 9 and be connected with pipeline 5; It is characterized in that: pipe 1 and outer tube 3 were among formed barrel-shaped in heater 2 was in.

2, compressor-free refrigerator according to claim 1 is characterized in that: the thermal elements in the heater 2 is to adopt posistor device, i.e. PTC element.

3, compressor-free refrigerator according to claim 2 is characterized in that: heater 2 is made up of PTC element 10 and metal shell 11.
