Abstract

A refrigerating air conditioner without compressor for vehicles or ship features that the afterheat exhausted from engine is used to heat the refrigerating generator in the air conditioner. Its advantages are no loss of engine power and fuel, long service life as there is no rotation friction, and high refrigerating power.

Description

Car (ship) is with compressor-free refrigeration air-conditioning and collocation method

Present (vapour, diesel oil) car air-conditioner all drives refrigerating compressor with driving engine and freezes, its shortcoming is: during air conditioner refrigerating, driving engine will additionally provide a part of power to compressor, not only cause the waste of the automobile-used energy, many consume fuel, (general vehicle will account for fuel consumption about 1/4th) and increase environmental pollution.

The useless cigarette waste heat that the objective of the invention is to utilize car (ship) driving engine to discharge absorbs, the diffusion type circularly cooling.The power of consumption of engine neither during air conditioner refrigerating need not be the refrigeration consume fuel again, owing to there is the compressor of present automotive use to rotate friction in the fridge equipment, the 2-5 that can reach vehicular compressed air conditioner service life doubly.The fuel cost that accumulative total is saved is considerable especially.

Accompanying drawing 1 is a principle of the invention scheme drawing

Number in the figure (1) is car (ship) driving engine; (2) be useless cigarette (heat) escape route; (3) be refrigerating generator; (4) be the noise reduction smoke exhaust pipe; (5) be fine stiller; (6) be condenser; (7) be evaporator; (8) be thermantidote; (in the general car is cold and hot shared) (9) are absorption reservoir; (10) be electromagnetic valve; (11) be connecting line between each refrigeration part; K ₁Be electromagnetic valve switch; K ₂Be the thermantidote switch.

Refrigerating generator 3 is made tubulose (being pectination in a pipe) end and is connected the useless cigarette escape route 2 of driving engine, the other end connects noise reduction smoke exhaust pipe 4, at first pass through refrigerating generator 3 when making driving engine give up cigarette (heat) discharge, make the producer inner refrigerant absorb heat and evaporation, the useless cigarette that has consumed heat enters exhaust to atmosphere behind the noise reduction smoke exhaust pipe again.Producer 3 connects fine stiller 5 by pipeline, fine stiller 5 connects condenser 6 by pipeline, condenser 6 connects evaporator 7 by pipeline, evaporator 7 connects absorption reservoir 9 by pipeline, absorption reservoir 9 connects electromagnetic valve 10 by pipeline, electromagnetic valve 10 is connected to producer 3 by pipeline, and another pipeline on the fine stiller 5 connects absorption reservoir 9, thereby constitutes the C/LOOP of fridge equipment.Electromagnetic valve and fan open-close on-off K ₁K ₂The interior power supply of connection car also is located on the car inner control platform.

When needing cold air in the car, connect K ₁, K ₂ Electromagnetic valve 10 conducting fans 8 start, useless cigarette waste heat behind the engine starting heats refrigerating generator 3, the explosive evaporatoin of in-to-in hybrid refrigeration working medium, become the mixed working fluid of gaseous state, after entering fine stiller 5, absorbent is cooled to flow of liquid earlier and returns absorption reservoir 9, refrigerant flows to into condenser 6 before continuing, heat radiation in condenser 6, be condensed into liquid, the indoor evaporator 7 that liquid refrigerant enters car (ship) is a gaseous state because the effect of the interior hydrogen of evaporator makes the refrigerant explosive evaporatoin, evaporation process strong absorption heat is realized refrigeration.Refrigerant is absorbed agent and is reduced to liquid after absorption reservoir 9, get back to producer 3 behind electromagnetic valve 10 again.Thereby realization refrigerating cycle.

Accompanying drawing 2 is gone up refrigeration (heat) interior environment system scheme drawing for the present invention is applied to motor omnibus (ship).

Number in the figure (1)-(11) parts are with identical described in Fig. 1, because passenger vehicle (ship) chilling requirement is bigger, therefore be provided with fan 14 separately, be provided with micropump 12 and mode of operation (hot and cold) change-over valve 13 on the producer delivery conduit, condenser 6 can be arranged at the top or the sidepiece of car according to the vehicle difference, and refrigeration principle is described identical with Fig. 1.When needed to heat in the car winter, conversion work mode change-over valve 13 made that evaporator 7 becomes condenser among the figure, and condenser 6 becomes evaporator, the refrigeration working medium counter-flow, thus send heat with 7 in the car (ship), be dissipated to outside the car (ship) cold with 6.

Relevant absorption-diffusion type air conditioner refrigerating (heat) principle does not describe in detail here for existing mature technology.

Because present automobile engine power is relatively large, when both having made the idle several work of the driving engine of less 1000CC discharge capacity, waste heat discharge also reaches more than the 3KW, and be that temperature is exported at the high energy more than 300 ℃, so reaching 0.6 (present absorption-diffusion type air conditioner refrigerating coefficient is all more than 0.8) refrigerating capacity, interior environment system coefficient of refrigerating performance of the present invention just is equivalent to the refrigerating capacity of vehicular compressed air conditioner, and after turning on the aircondition, to the almost not influence of takeoff output of automobile.Certainly, full-sized car driving engine more powerful, the useless cigarette waste heat of discharging is more, and the refrigeration surplus is bigger.

Because various visitors, lorry are to the demand difference of cold (heat) gas, the condenser of fridge equipment is provided with the different of position with evaporator, can in the connecting line of fridge equipment, electromagnetic valve be set as required, change-over valve, micropumps etc. are provided with requirement to reach and to satisfy different vehicle to refrigeration (heat) A/C.Refrigerant can adopt normally used ammonia, water, hydrogen or F in the existing mature technology ₂₂, water, and lithium bromide etc., the vehicle that use in the north will change into absorbent " water " antifreezing liquid to prevent the freezing fridge equipment of ice up in winter.When adopting different refrigerant, the connecting line and the refrigeration part of fridge equipment are also had nothing in common with each other, and can't narrate one by one here, and meaning of the present invention mainly is to provide a kind of energy savings, does not consume the car air-conditioner collocation method of automobile power.

The present invention both had been fit to vapour, diesel-engine vehicles (ship) uses, and also being fit to fuel such as alcohol, blue gas is that the vehicle powered boats and ships use.
