Definitions
- the present invention relates to an air conditioner having a heat exchanger.
- a conventional air conditioner has a housing, a first flow path, a second flow path, a tank unit, a cooling unit, a supply water path, and a recovery water path.
- a first outlet and a second outlet are formed in the housing.
- the first flow path is connected to the first outlet.
- the second flow path is connected to the second outlet.
- the tank unit holds water for cooling the first air flowing through the first flow path and the second air flowing through the second flow path.
- the cooling unit cools the first air by the heat of vaporization of the water held in the tank unit.
- the cooling unit includes a heat exchanger and an evaporation filter.
- the heat exchanger cools the second air by heat exchange with the water supplied from the tank unit, and cools the first air by heat exchange between the cooled second air and the first air.
- the evaporation filter cools the first air by the latent heat of the water supplied from the tank unit.
- the supply water path supplies the water held in the tank unit to the cooling unit.
- the second air flows along the second flow path from above to below the heat exchanger, passes below the heat exchanger, flows upward, and is blown out from a second outlet provided on the top surface of the housing. Because the second flow path includes a U-shaped folded portion, there is concern that the pressure loss of the second air will be large.
- the object of the present invention is to provide an air conditioner that reduces the pressure loss of the secondary air flowing through the heat exchanger compared to conventional air conditioners.
- An air conditioner comprises a housing, a first inlet arranged on a first side wall of the housing for taking in a first air into the housing, a second inlet arranged on the first side wall for taking in a second air into the housing, a heat exchanger having a first heat exchange flow path through which the first air taken in from the first inlet flows, and a second heat exchange flow path through which the second air taken in from the second inlet flows in an upward direction and through which water is supplied, an evaporative filter that cools the first air by the latent heat of water, a first outlet arranged on the housing through which the first air taken in from the first inlet and flowing through the first heat exchange flow path and the evaporative filter of the heat exchanger is blown out of the housing, and a second outlet arranged in the housing at a position above the outlet of the second heat exchange flow path of the heat exchanger, through which the second air taken in from the second inlet and flowing in the upward direction through the second heat exchange flow path is blown out of
- the air conditioner can flow the second air upward from the second heat exchange passage to the second outlet, and the pressure loss of the second air can be reduced compared to the conventional case. Because the first inlet and the second inlet are disposed on the same first side wall, the configuration inside the housing can be simplified compared to when the first inlet and the second inlet are disposed on different side walls, which contributes to reducing the size of the housing.

- the second fan 102 In the direction in which the first air flows through the first heat exchange flow path R1, the second fan 102 is disposed at a position overlapping with the heat exchanger 4.
- the second fan 102 circulates the second air through the second heat exchange passage R2 and has a smaller output than the first fan 101. More specifically, the diameter Y2 of the second fan 102 is smaller than the diameter Y1 of the first fan 101.

- the partition plate 105 is disposed between the first fan 101 and the second fan 102, and prevents the first air transported by the first fan 101 from mixing with the second air transported by the second fan 102.
- the partition plate 105 is the front wall of the first fan case 107.
- the fan motor 103 is disposed between the partition plate 105 and the first fan 101.
- the fan motor 103 is disposed in the second flow path P2, and the second air transported by the second fan 102 cools the fan motor 103. Therefore, the air conditioner 1 can efficiently cool the fan motor 103 by using the cold energy of the second air without increasing the temperature of the first air transported by the first fan 101.
- the air conditioner 1 drives the fan motor 103 to draw in air from the air-conditioned space through the intake port 74.
- the drawn-in air passes through the air filter 60 and flows into the heat exchanger 4.
- the air that flows into the heat exchanger 4 is divided into second air flowing through the second flow path P2 and first air flowing through the first flow path P1.
- the air conditioner 1 drives the pump 9 to supply water stored in the second tank 202 to both the second heat exchange passage R2 and the evaporation filter 6. A portion of the water supplied to the second heat exchange passage R2 and the evaporation filter 6 is collected in the second tank 202 via the drain pan 8. The first pipe 96 drips the water supplied from the second tank 202 by the pump 9 into the second heat exchange passage R2.
- the second air flows downward from the intake port 74, then turns upward at the first receiving portion 83 of the first drain pan 81, and flows upward through the second heat exchange flow passage R2.
- the second air and the water dripping from the first pipe 96 are mixed. More specifically, the second direction K2 from the inlet 56 to the outlet 50 of the second heat exchange flow passage R2, which is the upward direction, is opposite to the downward direction, which is the flow direction of the water supplied from the first pipe 96, so the water stays in the second heat exchange flow passage R2 for a longer period of time than when the second direction K2 and the flow direction of the water are the same.
- the water that accumulates in the second tank 202 includes water that has been recovered from the evaporative filter 6 after the air conditioner 1 is operated and has been cooled by the heat of evaporation. Therefore, the temperature of the water supplied from the second tank 202 becomes lower than the temperature of the second air immediately after it flows into the second heat exchange flow passage R2, depending on the operating status of the air conditioner 1.
- the second air is cooled by exchanging sensible heat with the water dripped from the first pipe 96.
- the second air is also cooled by the heat of vaporization when the water dripped from the first pipe 96 into the second heat exchange flow path R2 vaporizes.
- a first direction K1 from the inlet 57 to the outlet 58 of the first heat exchange flow path R1 of the heat exchanger 4 and a second direction K2 from the inlet 56 to the outlet 50 of the second heat exchange flow path R2 are perpendicular to each other.
- the second air flowing through the second heat exchange flow path R2 is cooled by water supplied from the second tank 202, and the first air is cooled by the second air.
- sensible heat exchange occurs between the first air and the second air via the sheet 45 of the partition wall 42.
- the second air After flowing upward through the second heat exchange flow path R2, the second air passes near the fan motor 103 arranged in the second flow path P2 and is discharged outside the air conditioner 1 from the second outlet 30.
- the second air cools the fan motor 103.
- a system that does not cool the second air using heat of vaporization such as air conditioner 1
- the second air may warm the blower duct 291 of the first air, causing the temperature of the first air to rise.
- the second air is also evaporatively cooled by heat exchanger 4, so there is a low possibility that the first air will be heated by the second air, compared to a cooling system that does not use evaporative cooling.
- Water supplied from the second tank 202 is dripped onto the vaporization filter 6 through the second pipe 97 provided on the top of the vaporization filter 6. Since the first flow passage P1 is kept at negative pressure, the water supplied from the second tank 202 is sucked into the vaporization filter 6 through the nozzle 922 of the second pipe 97 and permeates into the vaporization filter 6.
- the second vertical distance between the nozzle 922 and the vaporization filter 6 is 0, and air is unlikely to flow into the vaporization filter 6 through the opening 62 formed on the upper surface 69 of the vaporization filter 6.
- the water that permeates the vaporization filter 6 is vaporized by the passage of the first air through the vaporization filter 6, i.e., evaporated into water vapor, which is contained in the first air.
- the first air is cooled by the heat of vaporization at this time, and the temperature of the first air decreases.
- the cooled first air flows upward through the flow path forming portion 37, and is then blown out by the first fan 101 from the first air outlet 29 into the space to be air-conditioned.
- the air conditioner 1 can perform two-stage cooling of the first air blown into the conditioned space, including primary cooling by the heat exchanger 4 and secondary cooling by the evaporative filter 6. Therefore, the air conditioner 1 can further reduce the temperature of the first air compared to, for example, a direct evaporation method that uses only the evaporative filter 6.
- the air conditioner of the above embodiment includes a water storage container, a heat exchanger, a housing, and a drawer body.

When the drawer body of the air conditioner is moved to the drawer position, the heat exchanger can be disposed outside the housing.
- the drawer body of the air conditioner contributes to improving the ease of maintenance of the heat exchanger by users of the air conditioner.
- the air conditioner is provided with a first drain pan that is provided in the drawer body and receives water discharged from the second heat exchange flow path.
- the first drain pan of the air conditioner contributes to preventing water discharged from the second heat exchange flow path of the heat exchanger from adhering to unintended locations within the housing when the drawer body is moved to the drawer position.

- the second air outlet is positioned so as to overlap with the first air outlet in a direction perpendicular to the direction in which the first air flows through the first heat exchange passage. This allows the air conditioner housing to further simplify the flow path of the first air and the flow path of the second air within the housing, contributing to making the housing more compact.
- the air conditioner includes a first fan that circulates a first air through a first flow path that includes a first heat exchange flow path from a first inlet to a first outlet, a second fan that circulates a second air through a second flow path that includes a second heat exchange flow path from a second inlet to a second outlet, and a fan motor that drives the first and second fans.
