Abstract

The utility model discloses a vehicle air conditioner, belonging to the technical field of air conditioner technique, and composed of an energy storage tank, a circulating pump, a transmission pipeline, a heat exchanger, and a fan. The utility model can replace the electric compression type air conditioner which are generally used by the vehicle, achieving the air conditioner effect of cooling and heating by adopting the mode of adding an ice room and utilizing the afterheat generated by a vehicle engine, and having the advantages of energy saving, electricity saving, no use of a compressor, less noise, and no use of Freon. The utility model is good for protecting the environment from pollution. The utility model with an ice room can be used for the central air conditioners of cinemas and hotels.

Description

Vehicle air conditioner

The utility model relates to a kind of automotive air conditioning device of air-conditioning technical field, and this interior environment system of employing icebox mode can be widely used in the central air-conditioning in cinema and hotel etc.

At present automobile (manned passenger vehicle, the roadlice) A/C that generally uses all adopts electronic compression-type refrigeration air conditioner, produces " Hino " large-size air conditioning passenger vehicle etc. as Japan and all adopts this air conditioner.It is compared with other refrigeration modes, and its advantage is that coefficient of refrigerating performance is big, but its power consumption is too many and use fluorine Lyons as refrigerant, a large amount of uses in fluorine Lyons, the ozone layer of havoc atmosphere, contaminated environment, harmful human health, this is the shortcoming that electronic compression-type refrigeration mode can't overcome.International relevant department will limit the use of chlorofluoromethane refrigerant, and therefore, electronic compression-type refrigeration air conditioner will be eliminated all the time.

The purpose of this utility model is exactly in order to provide a kind of automotive air conditioning device to replace electronic compressed air conditioner machine, and the waste heat that adopts the icing station mode and utilize automotive engine to produce makes truck body reach the air-conditioning effect.

The utility model is to realize by following structure technology scheme: as shown in drawings, automotive air conditioning device is made of jointly the energy storage case 1 that adopts the icebox mode, circulation pump 2, delivery duct 3, H Exch 4, fan 5 etc.Its structure interconnected relationship is: outside face is with the energy storage case 1 that lagging jacket 6, inner face middle and lower part be equipped with netted dividing plate 9 and is connected with a plurality of (10～60) H Exch 4 by delivery duct 3 and the circulation pump 2 that outside face is with lagging jacket 6, H Exch is multi-disc thin metal foil radiating gill is installed on pipeline and is constituted, and the small-sized fans 5 with the H Exch respective numbers is installed between each H Exch.Its method that realizes air conditioning for automobiles is as follows: in hot day, (can electronic compression ice making from the ad hoc ice making storehouse of motor station on the way, and carry out ice making with other various ice making modes such as absorption type energy storage ice makings), take out ice cube and put into the energy storage case 1 of automobile lower, netted dividing plate 9 bottoms in the energy storage case are frozen water that ice cube dissolves generation, by circulation pump 2 and delivery pipe 3 CHP is delivered to H Exch 4, by H Exch 4 its ambient air is cooled, send in the railway carriage 8 by will the be cooled cold air of cooling of fan 5 again, make cooling in the railway carriage.Frozen water in the delivery duct 3 is through behind a plurality of Hs Exch, because absorption of air cold, make frozen water temperature build-up in the pipeline, because the effect of circulation pump, water after the intensification is pumped back to netted dividing plate 9 tops in the energy storage case 1 that ice cube is housed, and ice cube makes water for cooling become the bottom that frozen water flows to netted dividing plate 9 more again.So constantly come and go circulation, the cold that ice cube produces is delivered in the railway carriage, reach cooling-down air conditioner.After ice cube melted away entirely, the water in the energy storage case 1 no longer was a frozen water, just can open water discharging valve 10 at the bottom of the case, and water arrange back valve-off 10, put into ice cube at the top of case inlet again, in order to the use of continuation air-conditioning; During cold day, put into hot water in the energy storage case 1 and be communicated with the cooling water case of automotive engine, waste discharge hot air pipe with the automobile bottom taps into the energy storage tank inlet simultaneously, utilize its waste gas residual heat that hot water in the energy storage case 1 is constantly heated, make in the railway carriage by this automotive air conditioning device again and heat up, to reach the air-conditioning that heats up in the railway carriage.Its principle of work and cyclic process with hot day cooling-down air conditioner the same, the different colds of ice cube that just utilize hot day reach cooling in the railway carriage, and cold day is to utilize the waste heat of hot water and automobile to reach in the railway carriage to heat up.

The utility model is compared with the electronic compressed air conditioner machine that generally uses on automobile now, following advantage and effect are arranged: 1. can adopt coal combustion, coal gas, natural fuels etc. to come ice making, the power consumptive province for the energy and absorption type energy-storing refrigerating mode simple in structure, that efficient is higher; 2. without the motor driven compressor refrigeration, noise is low and do not adopt chlorofluoromethane refrigerant, can not destroy atmospheric ozone layer, helps protecting environment, helps human health; 3. can produce hot and cold wind, can realize the cooling in hot day and cold day intensification air-conditioning, make full use of the waste heat and the waste hot gas of driving engine generation in the running car again, have energy-saving effect preferably; 4. adopt this interior environment system of icebox mode, also can be used for the central air-conditioning in cinema, hotel.

As follows to description of drawings below: accompanying drawing is the automotive air conditioning device constructional drawing.1 is the energy storage case among the figure; 2 is circulation pump; 3 is delivery duct; 4 is H Exch; 5 is small-sized fans; 6 is lagging jacket; 7 are the energy storage tank inlet; 8 is truck body; 9 is netted dividing plate; 10 are energy storage case water discharging valve.

The contriver once utilized an automobile to implement this automotive air conditioning device, at first produce a top inlet is arranged with sheet metal, discharge port is arranged at the bottom, side has the energy storage case 1 in plumbing connection hole, weld netted dividing plate 9 in the case again, the case outside puts foam thermal insulation cover 6, energy storage case 1 is fixedly installed in the automobile bottom, 20 Hs Exch 4 that constitute by aluminium foil radiating gill and pipeline in automobile top both sides fixed installations again, between each H Exch, get out corresponding small-sized fans vent and install 20 small-sized fanses 5, by delivery duct 3 and the circulation pump 2 that is with foam thermal insulation cover 6 energy storage case 1 is connected with each H Exch 4 then, just makes this automotive air conditioning device obtain enforcement.After installing, once the wide dark highway to Shenzhen was tested in Guangzhou, from Guangzhou to Shenzhen 160 kilometers, adds 300 kilograms of ice cubes and just enough make this railway carriage cooling-down air conditioner in energy storage case 1.How many temperature in the railway carriage can be controlled by the quantity of enabling small-sized fans, when temperature is low, can close a part of fan to reach temperature suitable in the railway carriage at operator's compartment.
