Abstract

PROBLEM TO BE SOLVED: To ensure airtightness of a casing through a simple and easy structure. SOLUTION: Inlet side pipe parts 224c, 235c, constituting a heating medium inlet, are inserted into a first closing plate 210b and bonded thereto, while outlet side pipe parts 224b, 235d constituting a heating medium outlet are inserted into a second closing plate 210c and bonded thereto. Consequently, the inlet side pipe parts 224c, 235c can be jointed to the first closing plate 210b, and the outlet side pipe parts 224d, 235d can be jointed to the second closing plate 210d, regardless of manufacturing variation of the distance between the inlet side pipe parts 224c, 235c and the outlet side pipe parts 224d, 235d. Since an adsorption core 220 and an evaporation/condensation care 230 can be contained in a casing 210 without being affected significantly by the manufacturing variation thereof, airtightness of the casing 210 can be ensured using a simple and easy structure.

ISB 0122).

Next, the general operation of the air conditioner according to this embodiment will be described.

First, as shown in FIG. 1, the pump and the blower 410 are operated to allow the heat medium and the air to flow, and the switching valves 510 and 520 are operated to operate the first adsorber 2.
00 between the adsorption core 220 (core tube 222) and the outdoor heat exchanger 500, and the heat exchanger 330 of the second adsorber 300.
(Tube 331) and the outdoor heat exchanger 500, between the engine 100 and the adsorption core 320 (core tube 322) of the second adsorber 300, and the evaporation / condensation core 230 (tube 231) of the first adsorber 200. ) And the indoor heat exchanger 420. Hereinafter, such a state is referred to as a first state.

At this time, since the heat medium heated by the air blown into the room circulates through the evaporation / condensation core 230 of the first adsorber 200, the liquid refrigerant in the first adsorber 200 is evaporated and The air blown into the room is cooled by the heat medium cooled by the evaporating / condensing core 230 due to the latent heat of evaporation of the liquid-phase refrigerant.

At the same time, the adsorption core 220 of the first adsorber 200 adsorbs the evaporated gas-phase refrigerant to promote the evaporation. The adsorbent 221 generates heat (condensation heat) when adsorbing the gas-phase refrigerant, and when the temperature of the adsorbent 221 increases, the adsorbing capacity of moisture decreases. The heat medium is circulated between the core 220 and the core 220 to suppress the temperature rise of the adsorbent 221. Note that
The adsorber in such a state is called an adsorber in an evaporating / adsorbing state.

On the other hand, the suction core 320 of the second suction device 300
Since the cooling water of the engine 100 flows into the, the adsorbent 321 bonded to the adsorption core 320 is heated, and the adsorbed moisture is released (desorbed). At this time, since the heat medium cooled by the outdoor heat exchanger 500 is flowing through the heat exchanger 330 of the second adsorber 300, the desorbed gas-phase refrigerant (steam) flows into the heat exchanger 330. Is cooled and condensed. Hereinafter, the adsorber in such a state is referred to as an adsorber in a condensation / desorption state.

As described above, in the first state, the first adsorber 2
At 00, evaporation of the refrigerant and adsorption of the evaporated gas-phase refrigerant are performed, while, at the second adsorber 300,
Desorption of the adsorbed water and cooling and condensation of the evaporated gas-phase refrigerant are performed. Therefore, the evaporating / condensing core 230 of the first adsorber 200 functions as an evaporator for evaporating the liquid-phase refrigerant, and the heat exchanger 330 of the second adsorber 300 functions as a condenser for condensing the gas-phase refrigerant.

Next, when the operation in the first state has passed for a predetermined period of time, as shown in FIG.
Is operated to connect between the adsorption core 320 (core tube 322) of the second adsorber 300 and the outdoor heat exchanger 500, and between the evaporation / condensation core 230 (tube 231) of the first adsorber 200 and the outdoor heat exchanger 500. Between the engine 100 and the adsorption core 220 (core tube 222) of the first adsorber 200, and between the heat exchanger 330 (tube 331) of the second adsorber 300 and the indoor heat exchanger 420. Circulate. Hereinafter, such a state is referred to as a second state.

At this time, the heat exchanger 3 of the second adsorber 300
In 30, the heat medium heated by the air blown into the room circulates, so that the liquid-phase refrigerant in the second adsorber 300 is evaporated, and the heat of evaporation of the liquid-phase refrigerant is transferred to the heat exchanger 330 by the latent heat of evaporation. The air that is blown into the room is cooled by the cooled heat medium.

At the same time, the adsorption core 320 of the second adsorber 300 adsorbs the evaporated gas-phase refrigerant to prevent the pressure in the casing 210 from rising, and simultaneously prevents the outdoor heat exchanger 500 and the adsorption core 320 The heat medium is circulated between the heat sink and the temperature controller to suppress the temperature rise of the adsorbent 321.

On the other hand, the suction core 220 of the first suction device 200
In the first state, the adsorbent 221 adhered to the adsorption core 220 is heated in the first state, and the adsorbed water is released (desorbed). At this time, since the heat medium cooled by the outdoor heat exchanger 500 flows through the evaporation / condensation core 230 of the first adsorber 200, the desorbed gas-phase refrigerant (water vapor) is evaporated / condensed. Cooled and condensed in the core 230.

As described above, in the second state, the second adsorber 3
In 00, evaporation of the refrigerant and adsorption of the evaporated gas-phase refrigerant are performed, while in the first adsorber 200,
Desorption of the adsorbed water and cooling and condensation of the evaporated gas-phase refrigerant are performed. Therefore, the heat exchanger 330 of the second adsorber 300 functions as an evaporator for evaporating the liquid-phase refrigerant, and the evaporating / condensing core 230 of the first adsorber 200 functions as a condenser for condensing the gas-phase refrigerant.

When the predetermined time has elapsed, the first state is set again. As described above, the air conditioner (adsorption refrigerator) is continuously operated while repeating the first state and the second state at predetermined time intervals. The predetermined time is selected based on the moisture adsorption capacity of the adsorbent 221 in the adsorber 200 (adsorption core 220).
