Abstract

The utility model provides the technical proposal of a solar refrigerator by utilizing solar for heating. The technical proposal is characterized in that an ammonia collecting tank and a solar energy heat exchanger replace a generator of a conventional absorption refrigerator. A stop valve is arranged between a solution pump and an inlet of the solar energy heat exchanger. The stop valve is a conventional constant pressure stop valve. An overflow pipe is arranged between a throttle valve and the ammonia collecting tank. A spare gas fuel burner is arranged below the ammonia collecting tank.

Description

The solar refrigeration machine

The utility model relates to a kind of refrigerating plant, especially a kind of absorption solar energy refrigeration machine that utilizes solar energy.

Many in existing Absorption Refrigerator is cold-producing medium with ammoniacal liquor, generator just needs thermal source and heats like this, so, also just need to consume combustion gas, fire coal, fuel oil or utilize waste heat to come to heat to generator, therefore all to consume the energy of some, but also to have certain pollution to exist, this is the prior art unavoidable problem.

The purpose of this utility model is exactly at the existing in prior technology deficiency, and provides a kind of generally speaking without fuel, is to utilize the solar refrigeration machine technology scheme of inexhaustible solar energy for fuel.

For clearly demonstrating the technical characterstic of this programme, now by a specific embodiment, and in conjunction with its accompanying drawing, this programme made further elaborating.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment.

By accompanying drawing as can be seen, the solar refrigeration machine of this programme, it mainly is condenser 6 by liquefied ammonia that high pressure ammonia air cooling is congealed into, liquefied ammonia is delivered to sweat cooling in the evaporimeter 4 by choke valve 10 decompressions, ammonia after the evaporation absorbed in the absorber 3 absorbed into ammoniacal liquor by water, by solution pump 8 it is transported to again that generator constitutes, its characteristics are that described generator is made up of collection ammonia jar 1 and solar energy heat exchanger 5, and solar energy heat exchanger 5 described herein is exactly conventional shell and tube solar water heater.Between the import of solution pump 8 and solar energy heat exchanger 5 stop valve 7 is housed, this stop valve 7 is conventional constant voltage stop valve.Between choke valve 10 and collection ammonia jar 1, the overflow pipe 2 that can overflow ammoniacal liquor from choke valve 10 is housed also.Below collection ammonia jar 1, standby gas burner 9 is housed also.

As shown from the above technical solution, described generator is exactly a solar energy heat exchanger, ammoniacal liquor is passed in the solar energy heat exchanger by solution pump and stop valve by collection ammonia jar, in solar energy heat exchanger, be heated and produce the high pressure ammonia, high pressure ammonia pneumatic transmission to condenser condenses is become liquefied ammonia, liquefied ammonia is delivered to sweat cooling in the evaporimeter by the choke valve decompression, ammonia after the evaporation absorbed in the absorber again absorbed the ammonification current by water and return collection ammonia jar, by solution pump it is transported to solar energy heat exchanger again and finish once circulation, so continuous circularly cooling, as seen this programme is no longer used other any energy except that utilizing solar energy heating, does not also have any pollution.Ammoniacal liquor is too much in choke valve, then can ammoniacal liquor be defeated by collection ammonia jar by overflow pipe.If when night or winter solar can heat exchanger no longer can play heat effect, then can utilize additional gas burner heating collection ammonia jar, make the ammoniacal liquor evaporation in the jar, when raising, the ammonia evaporating pressure reaches the predetermined constant voltage of stop valve, stop valve is opened, the high pressure ammonia enters inoperative solar energy heat exchanger by stop valve, and transfers to the condenser cooling, and the later course of work is identical with aforementioned process.So as can be seen, this programme is when solar energy heat exchanger is ineffective, and this programme still can reach the refrigeration purpose with the absorption method of routine.Utilize this programme can be used for making any places that need refrigeration machine such as refrigerator, ice box or air-conditioning.This shows that the utility model compared with prior art has substantive distinguishing features and progress, its implementation result also is conspicuous.
