Description

Technical area

The invention relates to an air conditioning system that allows for vehicles and for multi-purpose air conditioning circuit.

State of the art

A system or equipment designed to dissipate heat from an environment by means of a cooling circuit (i.e., reducing ambient heat) and to supply the environment with fresh air, the excess moisture being removed from the environment, is referred to as an air conditioner.

Absorption cooling circuits used in air conditioners use heat energy for desorbing. Since the efficiency coefficients of cooling are low, high energy consumption is required. Since the cooling systems operate with absorption under vacuum, they require heat exchangers that have low heat losses. Therefore, the volume, weight and cost of the system are high. If a cooling system with absorption is used in the vehicles, the cooling circuit will not work until the engine of the vehicle warms up and so the level of comfort will decrease. Steam compression, steam jet ejector, adsorption and absorption cooling systems are costly because they use heat exchangers for heat transfer to the air. Since a large part of the cooling energy used for air conditioning is used to condense the water in the air, the energy consumption is high. Since the air ducts used for transporting the conditioned air have large cross sections, especially in the case of vehicles, an installation problem arises. This is expensive. As a result of the acceleration of the air to overcome the pressure losses creates a noise. There is a need to use complicated and expensive filter systems to clean the air to be used for the purpose of air conditioning.

In the Japanese Patent Document JP 11223429 , which belongs to the prior art, a dryer is described, which is arranged during manufacture in the air conditioning in order to reduce the degree of humidity in the cooling circuit.

Brief explanation of the invention

The object of the invention is to provide an air conditioning system, which consume much less energy compared to the cooling systems with absorption, which work by heat and to all other cooling systems, because its efficiency coefficient for cooling (STK) is much larger.

A further object of this invention is to provide an air conditioning system which requires less space, is light and inexpensive because this system requires no heat exchangers for vapor-liquid and liquid-to-liquid transitions, although operating under vacuum.

A further object of this invention is to provide an air conditioning system which does not require a heat source for desorption and consumes approximately the same amount of energy as compared to a refrigeration system having the same performance as the absorption systems using a heat source, wherein it is not required is that the heat sources are ready when this system is used in vehicles.

Another object of this invention is to provide an air conditioning system which is very inexpensive because no heat exchangers are used in transferring the heat of the cold and warm medium to the air (evaporator, condenser).

Another object of the invention is to provide an air conditioning system in which the cooling energy required for air conditioning of the same volume is less, because the moisture in the air is drawn off by the dense liquid before cooling.

Yet another object of the invention is to provide an air conditioning system whose vent duct dimensions are smaller because less air is transported and the pressure of the transported air is slightly higher than atmospheric pressure and the specific volume becomes smaller, around a constant volume environment for the purpose ventilate the air conditioning.

The invention has another object to provide an air conditioning system in which no problem of noise increase originating from the air duct is experienced, which could depend on the air outlet speed, since the air outlet speed from the fan not by the speed of the air within the channel but by the change in their pressure can be corrected.

Another object of this invention is to provide an air conditioning system in which fresh air conditioning air is always provided because the fluid is filtered throughout the cycle and there is no need for expensive, complicated air filters.

In an embodiment of the invention; located at the top of the first container ( 2 ) working under vacuum and two chambers ( 3 ) and of lines ( 4 ), which allow passage between the chambers, distilled water or other primary cooling medium (SS) used in the cooling systems with absorption, but in the lower part is absorbed water (Li-Br, salt, ethylene glycol, and the like) (YS) or another secondary cooling medium used in the cooling systems with absorption (water and the like for the ammoniacal system with absorption). Between two chambers is the line ( 4 ), which ensures the suction of the vapor of the primary cooling medium (SS) by the secondary cooling medium (YS). With the vacuum value created by absorption of the primary cooling medium (SS) vapor by the secondary cooling medium (YS), the evaporation of the primary cooling medium (SS) continues. Since heat is dissipated during evaporation from the primary cooling medium (SS), the fluid temperature decreases.

The cooled medium is pumped ( 9 ) in the first chamber of the second container ( 5 ) under atmospheric pressure or a little above. The air to be conditioned, which is taken separately from the environment to be air-conditioned (IE) and / or from the external environment (DE) or from these two environments and mixed and drawn in by means of a mixer (M), is conveyed by means of the air pump (FIG. 11 ) in the upper chamber of the first container ( 2 ) under the same pressure as the cooled medium (SS). The air, before it penetrates into the liquid, with the help of the capillary tube ( 6 ) is sucked and absorbed by the secondary cooling medium (YS) whose moisture content is high. The air rises due to the density difference to the upper part of the upper chamber of the second container ( 5 ) as bubbles up and accumulates there. The liquid in the form of a bubble allows the transfer of its heat into the primary cooling medium (SS) through a large heat transfer surface. Since the pressure value in the upper chamber in the second container ( 5 ) is higher than the partial vapor pressure of the moisture in the air, so there can be no moisture in the air. The remaining moisture content is determined by means of capillary tube ( 6 ) is transferred to the secondary cooling medium (YS), which has a higher density. Since the moisture content in the air is liquefied at the inlet and at the outlet, so too are the harmful gases and particles in it together with the liquefied water vapor cleaned. Further, the air is filtered because it is passed through the medium.

Now that the cooling medium is filtered over the entire cycle, so pure air conditioning air is always provided.

The cooled, purified and moisture content controlled air conditioning air, which has a pressure above atmospheric pressure, through air channels ( 12 ) to the inlet openings of the air blower ( 13 ) with the help of accelerators ( 15 ) sprayed. Since the inlet of the blower ( 13 ) is open to the environment, a vent (VAK) is formed behind the blower by Venturi effect and the ambient air is sucked in, mixed with cooled air and routed through routers ( 16 ) into the environment. Depending on the request, in the rear part, the air intake part (VAC) of the blower ( 13 ) a mechanical or electrical filter are arranged, whereby the air is filtered.

As long as the dense secondary cooling medium (YS) located in the lower chamber of the first vessel sucks in the vapor of the first medium, its density is reduced and, on the other hand, its temperature increases. The secondary medium is pumped by the pump ( 9 ) with the same pressure and / or a delta pressure in the lower chamber ( 5 ) of the second container ( 5 ) pumped. The air to be conditioned, which is taken separately from the environment to be air-conditioned (IE) and / or from the external environment (DE) or from these two environments and mixed and drawn in by means of a mixer (M), is pumped by the air pump (FIG. 11 ) is fed into the secondary cooling medium (YS) and also accumulates because of the density difference in the upper region of the chamber. The heated, filtered compressed air can be used as heating air for the purpose of air conditioning or the heat taken from the inside space can be dissipated to the outside environment by spraying.

If an air conditioning system ( 1 ) is used for the purpose of heating or cooling, so many three-way air valves (v3, v4) can be used. In this way, the desired air temperature can be achieved by injecting some or all of the warm and cool air to the environment. The valve controls can be switched manually or electrically.

Which is in the lower chamber of the second container ( 5 ), cooled dense fluid (medium) (YS) is by means of a tube (B) to the separation vessel ( 7 ), wherein the process of reverse osmosis again the first medium (SS) is obtained by the medium under pressure through the filter ( 8th ) is guided. If the pressure required for the osmosis process is insufficient, an additional pump may be used. The first medium reduced as a result of the evaporation is supplemented by removing the primary medium (SS) obtained from the second container ( 5 ) is supplied to the medium in the upper chamber (SC). The circulation is completed by the first heated medium in the upper chamber of the second container ( 5 ) is fed by means of a conduit via a reducing valve or a nozzle back into the upper chamber of the first container. The dense second medium (YS), which is not passed through the filter is, through a pressure reducing valve in the lower chamber in the first container ( 2 ) and so the density loss is compensated.

It is quite possible, various embodiments of the air conditioning system according to the invention ( 1 ) and the invention should not be limited to the embodiments described herein, being essentially as stated in the claims.
