Description

[Detailed Description of the Invention] This invention is based on a method for cooling the interior of various automobiles.

Conventionally, the method used to cool automobiles was to use a known compression type air conditioner and use engine power to disturb the compressor, but when the engine was running at low speed or stopped, cooling could no longer be performed and a system problem occurred. If you encounter a traffic jam or slow driving for a long time, you will not be able to get any cooling function at all, causing severe mental and physical fatigue for the driver, which has major disadvantages in terms of comfort and traffic safety.In addition, cooling will reduce fuel consumption. increased, and there were also drawbacks in terms of minorness.

In view of the above-mentioned circumstances, an object of the present invention is to maintain sufficient air conditioning even when the engine is at low speed for a long period of time or is stopped while driving. It is an object of the present invention to provide a method for performing air conditioning with improved layer efficiency.

The characteristic means of the cooling method for an automobile according to the present invention is to release crystal water from the inorganic salt hydrate in the ill or the second tank by heating using engine exhaust gas as a heat source, and to transfer the released crystal water to the eighth or fourth tank. The cooling energy is stored by cooling and condensing, and the cooling energy is stored first by using the inorganic salt next to the dehydration area in the second or first tank and the water in the fourth or eighth tank. The water in the first or eighth tank is evaporated by heating using the air inside the car as a heat source, and the latent heat of evaporation is absorbed as crystal water while cooling the water vapor to 6g or the lil salt in the first tank. Inside the car for use? t#N1 in parallel, and the cooling energy accumulation and vehicle interior cooling are performed alternately for the l and 8th tanks and *g and 4th tanks.

The effects of the characteristic means of the present invention are as follows.
In other words, by storing cooling energy and cooling the inside of the car using the stored cooling energy in parallel and mutually for a pair of equipment, it is possible to not only achieve continuous cooling over a long period of time, but also to cool the car even if the car is stuck in a traffic jam or while driving slowly. Even if the energy required for air conditioning cannot be obtained from the engine for a relatively long period of time, the cooling energy that has already been accumulated through chemical reactions will be used to maintain sufficient interior cooling.
K has been developed to provide extremely effective interior cooling for automobiles in a situation where the correspondence situation has worsened in recent years.
It became.

E. The thermal energy of the engine exhaust gas, which was not used at all when cooling was required, is effectively used as the main energy for cooling, so the increase in FFI consumption due to cooling & U is extremely small, which has become an important issue in recent years. It has become possible to cool the inside of a car extremely advantageously even in terms of energy saving and low energy consumption.

By the way, to cool the inside of the car by effectively using the thermal energy key of engine exhaust gas, it is possible to use Kochi's absorption type air conditioner, but absorption type? tJIIi is extremely unsuitable when the cooling energy gate structure is subject to large equipment space restrictions such as in automobiles, and is vulnerable to equipment characteristics and vibrations, and is comparable to the method of the present invention in terms of practical VC. So no Fi 0
Next, an example will be described.

In addition to providing the 8th heat exchanger n and asi, the 5th heat exchanger nt set and the 8th heat exchanger 4 are installed and the 6th heat exchanger *Q? l to 11i7 heat exchanger barrel (connecting the first state, mIS heat exchanger an to the seventh heat exchanger O barrel, and connecting the sixth heat exchanger I to the eighth heat exchanger) IB2 state A gtIt path switching valve g41ic is provided for switching between the gtIt path and the gtIt path switching valve g41ic.

Note that an appropriate liquid such as water is used as the heat transport medium.
The heat transport medium is circulated by means of holes installed at appropriate locations.
