Description

AN AIR CONDITIONING SYSTEM
Field of the Invention
The present invention relates to an air conditioning system with liquid desiccant that supplies air which is conditioned and free-of-bacteria into the vehicle cabin.
Background of the Invention
Daily problems such as corrosion of the metals, rotting of food and wood, mold growth, reproduction of fungi, skin getting sticky and agglomeration of powder food products, distortion of wooden furniture, difficulty in breathing, encrusting or color change of food products occur particularly due to humidity changes in addition to temperature changes. This situation which makes life conditions difficult and causes loss of property and money is particularly related with high levels of humidity. Humidity, which changes according to climate and weather conditions out of human control, is the most important factor that harms human health and property comfort.
Air can retain only a certain amount of water vapor at certain temperature. Relative humidity of saturated air which cannot hold any more moisture is 100%. As temperature of the air increases the amount of water vapor it can hold increases, and the said amount decreases as its temperature decreases, because as the air gets colder, a part of the vapor that it holds will condense and transform into water. Therefore when unsaturated air is cooled to a certain temperature degree, it reaches saturation point and when it is further cooled, moisture is separated from the air in the form of water droplets. This temperature is called "dew point". Thus, one way of eliminating the excessive humidity in the air is to cool the air so that its temperature drops below the dew point. A second method is passing the air over hygroscopic substances. Heating, cooling and ventilation systems are the leading systems that provide comfort in the vehicles. When the outer environment is hot or cold, in-cabin temperature should be maintained at a normal level and the cabin should be ventilated.
United States patent document no. US6216489, an application known in the state of the art, discloses an air conditioning system which enables to cool air with liquid desiccant. The liquid desiccant which absorbs moisture is recovered by an evaporator. The vapor resulting at this stage can be used for cooling the dry air after being cooled and condensed.
United States patent document no. US20140223947A1, an application known in the state of the art, discloses a temperature and humidity control device. It is stated that a liquid desiccant is used in the said system for dehumidifying the air and furthermore it is stated that LiCl can be preferred as the liquid desiccant solution. The air required for the operation of the liquid desiccant is cooled at the evaporator and a second liquid desiccant is introduced. United States Patent document no US4939906A, an application known in the state of the art, discloses a system with liquid desiccant which is developed for use in air conditioning. In the said system, LiCl liquid desiccant is used and it is disclosed that an evaporator is used for recycling the desiccant. United States patent document no. US4205529A, an application known in the state of the art, discloses a hybrid air conditioning system. It is disclosed that the said system employs a desiccant including LiCl solution and an evaporator in order to enable the air entering into the liquid desiccant to be moist. Coolants used in vehicle cooling systems are expensive and harmful for the environment. The legal regulations have brought the obligation to develop coolants which are less harmful for the environment; therefore costs of the coolants have increased.
In vehicle cabin cooling systems, more than half of the cooling power is used for condensation of the latent heat, in other words the humidity in the air. This increases energy consumption of the vehicle air conditioning system while also increasing size, weight and accordingly cost of the HVAC assembly and installation. Problems Solved by the Invention
An objective of the present invention is to provide an air conditioning system which condenses the moisture in the latent heat of the outer air and converts it to heat, and thus obtains dry and temperature-adjustable air without consuming energy.
Another objective of the present invention is to provide an air conditioning system which has a high performance coefficient (COP). A further objective of the present invention is to provide an air conditioning system which enables the air entering into the compartment to be anti-bacterial.
Another objective of the present invention is to provide an air conditioning system which enables to heat and cool the air by using the excess moisture that is condensed.
Detailed Description of the Invention
An air conditioning system developed to fulfill the objective of the present invention is illustrated in the accompanying figure, in which: Figure 1 is a schematic view of the air conditioning system.

H. Outer environment air
The air conditioning system (1), which supplies dry and hot or cold air free-of- bacteria into the vehicle cabin, basically comprises
at least one HVAC module (2) which conditions the air blown into the cabin, at least one liquid desiccant cycle (3) in which the air blown into the cabin is dried and which enables to recover the liquid desiccant that carries out the drying process,
- at least one water cooling coil (4) which enables to cool the water vapor resulting in recovery of the liquid desiccant, at least one drain (5) through which the excess water cooled in the water cooling coil (5) is discharged to the outer environment,
at least one atomizer (6) which enables the air to be re-humidified by injecting the water cooled in the water cooling coil (5) to the HVAC module (2).
The air conditioning system (1) of the present invention intends to supply dry and temperature-adjusted air which is free-of-bacteria into the vehicle cabin.
The HVAC module (2) comprises
- at least fan (21) which enables to blow air into the cabin,
at least one heating coil (22) which enables to heat the air,
at least one cooling coil (23) which enables to cool the air,
at least one intake air flap (24), which is located between the air inlet from the cabin and the air inlet from the outer environment, and which selects the air that is to enter the module by closing one of the two inlets by its movement, at last one heating flap (25) which is located in front of the heating coil (22) and which, when it is open, enables the air to pass through the heating coil (22), and when it is closed, prevents the air from passing through the heating coil (22).
The liquid desiccant cycle (3) comprises
at least one storage (31) wherein the liquid desiccant is stored and mixed with outer environment,
at least one pump (32) which pumps liquid desiccant for recycling thereof, - at least one evaporator (33) which evaporates the moisture absorbed by the liquid desiccant,
at least one desiccant cooling coil (34) which enables to cool the liquid desiccant before returning to the storage (31),
an ejector (35) which enables the pump (32) to drive the desiccant by forming a vacuum. The outer environment air (H) is passed through the desiccant in the storage (31) containing liquid desiccant as air bubbles and thus the desiccant is enabled to absorb the moisture of the air. The dried air is then delivered to the HVAC module (2). The desiccant, whose concentration decreases due to the water condensed from the air, is delivered to the evaporator (33). The water in the desiccant is evaporated by means of the engine waste-heat or the heat provided by a heat source such as an electrical heater. The desiccant, whose concentration is increased by evaporating the water therein, is absorbed by means of the vacuum formed in the ejector (35) upon absorption of the desiccant with reduced concentration from the storage (31) by the help of the pump (32) and returning it back to the container by means of the ejector (35); and it is cooled while being passed through the desiccant cooling coil (34). Thus, the desiccant, in which the water absorbed from the air is evaporated, and which is cooled, becomes ready to absorb moisture from the air.
The water evaporated from the desiccant in the evaporator (33) passes through the heating coil (22), water cooling coil (4) and the cooling coil (23), and is discharged to the outer environment through the drain (5) or is injected to the air supplied to the cabin via the atomizer (6).
In summer mode operation; the water vapor delivered to the heating coil (22) passes without being cooled here since the heating flap (25) is closed. It is condensed in the water cooling coil (4) and its temperature is brought to a temperature near the outer environment air (H) temperature. The condensed water is passed through the cooling coil (23) and it is used for cooling the air, which is somewhat heated due to condensation of the moisture therein, and for bringing it to a temperature near the outer environment air (H) temperature. A part of the water is discharged to the outer environment through the drain (5) and thus the heat received from the air is enabled to be discharged to the outer environment. Another part of the water is atomized and injected into the dry air by the help of the atomizer (6) and evaporative cooling is obtained. In winter mode operation; the water vapor delivered to the heating coil (22) is condensed here thereby heating the air since the heating flap (25) is open.
