Description

[Title established by the ISA under Rule 37.2] PORTABLE AIR CONDITIONER
The present invention relates to a portable air-conditioning device with improved cooling capacity.
In general, air-conditioning devices comprise an internal unit and an external unit, and the heat drawn from the internal unit during cooling is discharged to the outer environment by the external unit. In portable (transportable) air-conditioning devices, cooling is usually performed by discharging the heat drawn from the ambiance to the outer environment by means of a vent extending outdoors through an aperture opened on a window or a wall. However, the vent structure that enables heat to be discharged to the outer environment, restricts transportability of the air-conditioning device. In addition, portable air-conditioning devices are not preferred by many users since an aperture to be opened on a window or a wall for the vent needs to be formed suitably, in order to obtain an efficient cooling performance by providing insulation between the ambiance that requires cooling and the outer environment. This problem can be eliminated with applications in which a part of such residual heat is stored in a thermal storage member without discharging to the outer environment. In portable air-conditioning devices, storage of residual heat which has to be discharged to the outer environment, using phase change material (PCM) with high heat storage capacity, is known. The spin speeds of the compressor and the evaporator fan vary according to the temperature, humidity level and the cooling need of the environment which is desired to be cooled. In cases of increased need for cooling, for example in high ambient temperatures, the spin speeds of the compressor and the fan increase, leading to an escalation of noise levels and energy consumption. The amount of heat to be discharged from the condenser also increases, shortening the usage period of the PCM packages collecting heat. When the portable air-conditioning device is operated in the sleep mode or the silent mode in which the speeds of the compressor and the fan is kept low, cooling duration is extended and desired levels of cooling cannot be maintained.
United States patent application no. US5964098(A) relates to an air-conditioning system comprising an auxiliary condenser connected in series between the compressor and the main condenser.
German patent application no. DE2712110 (A1) relates to a combined heating-cooling system in which a coolant is directed to an auxiliary condenser upon the coolant pressure or the coolant temperature exceeding a target value.
French patent application no. FR2886388(B1) relates to a heating and cooling system comprising an auxiliary heat exchanger.
United States patent application no. US4404814(A) relates to an air-conditioning system comprising an auxiliary condenser.
The aim of the present invention is to realize a portable air-conditioning device whose cooling capacity is increased in cases of increased need for cooling.
The portable air-conditioning device provided to achieve the aim of the present invention is disclosed in the claims.
In the portable air-conditioning device of the invention, in cases of high need for cooling, for example when the ambient temperature and humidity is increased, or when the device is operated in silent mode or sleep mode, the coolant leaving the main condenser is directed to an auxiliary condenser by means of a multiport type valve, and the auxiliary condenser is activated together with the main condenser. The auxiliary condenser is placed in the heat storage chamber in which the PCM packages made of phase change material are arranged, and transfers heat to the PCM packages. The heat discharged from both the main condenser and the auxiliary condenser is stored by the PCM packages.
In an embodiment of the invention, the PCM packages are at least partially in contact with the auxiliary condenser in the heat storage chamber, and transfer and store the heat of the auxiliary condenser by way of heat conduction. In this embodiment, the auxiliary condenser is preferably made by being bent in serpentine shape, and the PCM packages are placed between the meanders (passes) of the auxiliary condenser.
In an embodiment of the invention, the PCM packages are placed in the heat storage chamber so as not to contact the auxiliary condenser, and they transfer and store the heat of the auxiliary condenser by way of heat convection.
In the portable air-conditioning device of the invention, cooling capacity is enhanced by activation of the second condenser in cases of increased need for cooling, providing a noiseless operation and saving energy.
The portable air-conditioning device provided to achieve the aim of the present invention is illustrated in the accompanying drawings, wherein:

The portable air-conditioning device (1) of the invention comprises,

In an embodiment of the invention, the portable air-conditioning device (1) comprises a first flow line (12) arranged between the valve (10) and the evaporator (5), enabling conveyance of the coolant from the main condenser (3) directly to the evaporator (5) “by-passing the auxiliary condenser (9),” by directing of the valve (10) when the auxiliary condenser (9) is not activated, and a first expansion member (13), for example a capillary tube or an expansion valve, arranged on the first flow line (12), enabling expansion of the coolant leaving the main condenser (3).
In another embodiment of the invention, the portable air-conditioning device (1) comprises a second flow line (14) arranged between the valve (10), the auxiliary condenser (9) and the evaporator (5), enabling conveyance of the coolant from the main condenser (3) to the auxiliary condenser (9), and in turn to the evaporator (5), when the second condenser (9) is activated by the control unit (11) and the valve (10), and a second expansion member (15) for example a capillary tube or an expansion valve, arranged on the portion of the second flow line (14) between the auxiliary condenser (9) and the evaporator (5), enabling expansion of the coolant leaving the auxiliary condenser (9).
In another embodiment of the invention, the PCM packages (7) are at least partially in contact with the auxiliary condenser (9) in the heat storage chamber (8), and they transfer and store the heat of the auxiliary condenser (9) by way of conduction. In this embodiment, the auxiliary condenser (9) is made by being bent in serpentine shape, and the PCM packages (7) are placed between the meanders (passes) of the auxiliary condenser (9) (figure 3).
In another embodiment of the invention, the PCM packages (7) are placed in the heat storage chamber (8) so as not to contact the auxiliary condenser (9), for example side-by-side with the PCM packages (7). The PCM packages (7) transfer and store the heat of the auxiliary condenser (9) by way of convection (figures 1 and 4).
In another embodiment of the invention, the portable air-conditioning device (1) comprises a condenser chamber (16) in which the main condenser (3) and preferably the compressor (2) is placed, a partition wall (17) separating the heat storage chamber (9) from the condenser chamber (16), and an opening (18) provided on the partition wall (17), enabling conveyance of the heat discharged from the main condenser (3) to the heat storage chamber (8) and the PCM packages (7) to store the heat of the main condenser (3) (figure 3).
In another embodiment of the invention, the portable air-conditioning device (1) comprises an evaporator chamber (19) in which the evaporator (5) and the evaporator fan (6) is placed, and a heat-humidity sensor (20) placed in the evaporator chamber (19), measuring the temperature and the humidity of the air sucked from the environment by the evaporator fan (6) (figures 1 and 2).
The control unit (11) enables the activation of the auxiliary condenser (9) by means of the valve (10) according to data it receives from the heat-humidity sensor (20), upon the temperature and the humidity of the ambient air exceeding the limit values prerecorded by its memory (figure 2).
In the portable air-conditioning device (1) of the invention, cooling capacity is enhanced by activation of the auxiliary condenser (9) in cases of increased need for cooling, for example when the ambient temperature and humidity is increased, or when the device (1) operates in silent mode, saving energy.
