Abstract

Pump-less absorption replacement refrigerator is a power with low grade heat energy, replaces compressor or solution pump, makes simply, with low cost, and noiselessness is widely used in having automobile, boats and ships, solar energy, chemical industry and the civil area of a large amount of used heat.Its principle is: concentrated solution is boosted through heating, go out pure steam cooling and coagulate usefulness, weak solution after the generation is pressed to the absorption edge spray and is absorbed, become highly concentrated solution, after generation and absorption finish, generator and absorber transposition take place and the inverse process that absorbs, thereby finish continuous running.

Description

Pump-less absorption replacement refrigerator

The refrigeration system of extensive use at present generally is compressed to condensing pressure with compressor with low-pressure steam, and absorption system makes steam be forced into condensing pressure with the method for heating, and absorbs between the high pressure generation with a solution pump delivered solution in low pressure.In fact, because there is very big pressure differential in pump two ends,, very high technological requirement is arranged, and have energy consumption problem equally so it is the same with the manufacturing compressor to make solution pump.

The present invention is a kind of pump-free type absorption replacement refrigerator, available low grade heat energy is a power, replace compressor or solution pump, cooling effect is good, make simply, with low cost, there is not the machinery running, noiselessness is widely used in having the industry and the civil area such as automobile, boats and ships, solar energy, chemical industry, pharmacy of used heat.

Below in conjunction with accompanying drawing the principle of the invention is described in detail.(seeing accompanying drawing 1)

Deliver to generation absorber (1) by the heat source water (generally more than 70 ℃) that the magnetoelectricity reversal valve distributes, cooling water is delivered to when absorber (2) takes place, (1), (2) include helical pipe parallel connection type heat exchanger, (1) Nei heat exchanger has been passed to ammoniacal liquor concentrated solution therebetween with thermal source heat, and solution pressure is raise, when being elevated to condensing pressure, the preceding valve of spray nozzle (a) is opened, spray nozzle (a) spray, ammonia steam is overflowed in concentrated solution, by unidirectional air outlet valve, enters the rectifying layer that the space is full of filler, heat exchange action in the rectifying layer, purer steam are sent to condenser condenses and become refrigerant liquid; The weak solution that finishes through spray nozzle (a) sprays at spray nozzle (b) by heat exchanging pipe and check valve, thereby the refrigerant vapour that absorbs flash-pot to come through breather check valve, absorbing heat is taken away by the helical pipe heat exchanger that absorbs in the generator (2), spray when taking place and absorbing spray in liquid, and its mobilization dynamic is the pressure differential that relies on the solution heating to boost and produce.In above process, because action of pressure, the breather check valve that absorbs generator (1) is closed, outgassing nonreturn valve is opened, the breather check valve that absorbs generator (2) is opened, outgassing nonreturn valve is closed, i.e. the placement of these check valves be the valve of breather check valve to seeing that from evaporimeter the past opens, the valve of outgassing nonreturn valve is to seeing that from condenser the past closes.

After above process finished, the concentrated solution spray that promptly takes place in the absorber (1) finished, and magnetoelectricity wink, logical reversal valve commutated heat source water and cooling water under the control of time controller, and made duty displacement in (1) and (2), continued to take place and absorb.The operation principle that magnetoelectricity wink is led to reversal valve is: (seeing accompanying drawing 2) places two pairs of solenoids outside the cylinder permanent magnet (magnetic pole is two utmost points) of tape spool, every pair of coil opposition produces south poles magnetic field, when two pairs of solenoids exchange perfectly straight stream (or pulsating direct current) electricity, the cylinder permanent magnet just can be done 90 ° of rotations, axle just drives spool and does 90 ° of actions back and forth, when two groups of coils all cut off the power supply, because the magnetic attraction effect of cylinder permanent magnet.And can continue to remain under this state, thereby the spool that is connected with the permanent magnetism axon keeps its valve to state equally.

Condenser (3) and evaporimeter (4) adopt helical pipe parallel connection type heat exchanger, (seeing accompanying drawing 3) for saving the metal material simplified manufacturing technique and reducing volume.All be with the conveyor screw of spring-like at the outer wall of every round metal tube, fluid is along helical flow after the socket, participate in cold and hot two groups of fluids of heat exchange and be connected in import and outlet is alternately introduced respectively and drawn, therefore arbitrary group of fluid all can carry out the caloic exchange with internal layer and outer another group fluid when helical flow.

To replace the divergence state of generation in order overcoming, thereby to make the curve that freezes straight, can increase by one to two generation absorber, one to two generation absorber of maintenance at the preparation state with the starting stage appearance that absorbs the position.

Claims

Absorbed generator, turnover gas (liquid) check valve, helical pipe parallel connection type heat exchanger (condenser, evaporimeter), magnetoelectricity wink led to the pump-less absorption replacement refrigerator that reversal valve and pipeline etc. are formed by two or more (even number) solution, its technical characterictic also comprises:

1, the displacement of duty is to reach by the hot and cold water that heat exchanger in the absorber takes place the logical reversal valve exchange of magnetoelectricity wink.
2, liquid its mobilization dynamic when spray taking place and absorb spray is the pressure reduction that relies on the solution heating to boost and produce.
3, the valve of breather check valve is to seeing that from evaporimeter the past opens, and the valve of outgassing nonreturn valve is to seeing that from condenser the past closes.
4, solution spraying depends on that solution pressure is greater than condensing pressure.
5, all heat exchangers such as evaporimeter, condenser all adopt helical pipe parallel connection type heat exchanger.
6, lead to reversal valve magnetoelectricity wink and after each commutation, can cut off the electricity supply, and can continue to keep this valve to state.
7, the rectifying mode of steam is the filling space exchange type.
8, according to the feature of claim 6, the mobile of cold and hot two components of helical pipe parallel connection type heat exchanger is rotational flow.And wherein arbitrary group of solution all can carry out heat exchange with lining tube wall and outer wall.
