Abstract

PURPOSE:To simplify the maintenance and service with respect to the titled air conditioner without requiring any special machine or any control device for transporting an adsorbent by causing indoor air to flow through a flowpath of a circulating cycle, and utilizing the flow of indoor air to circulate the adsorbent, with respect to a fluidized bed type air conditioner using a moisture absorbent such as zeolite or a molecular sieve. CONSTITUTION:A fluid bed forming a dehumidifying bed 2 is of a multistage structure partitioned by wire nets 8, 8..., for example, and transports uprising air successively to upper stages as the uprising air agitates the adsorbent. On the other hand, the contact of air with the adsorbent causes the adsorbent to rise up in the same manner. In addition, a regeneration bed 1 is constituted so that the adsorbent which falls from a hopper 6 by gravity is developed onto a dispersion plate 9, and discharges moisture to uprising heated air. On the other hand, the adsorbent successively falls onto a dispersion plate 9 in a subsequent stage via a downcorner 10 opening in the vicinity of the dispersion plate 9. As the heated air supplied to the regeneration bed 1, is used heated air obtained by a solar heat collector 12, for example. On the other hand, air which air-conditions the interior of the room R flows into the dehumidifying bed 2 while involving the adsorbent of a high temperature, falling the regeneration bed output 18, and rises up while discharging moisture to the adsorbent in the dehumidifying bed 2. The thus obtained dry air is suitably humidified by a humidifier 18 and is recirculated within the room.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner using a moisture adsorbent such as zeolite or molecular sieve.

Conventional air conditioners generally use a motor to drive a refrigerant compressor and use phase changes in the refrigerant to regulate temperature.

-Although it has a humidification mechanism, such electric refrigerators consume a lot of electrical energy and require a closed cycle of high-pressure refrigerant, making them prone to breakdowns. It also has the disadvantage of being a hassle to maintain.

Additionally, Kusaki admixture machines that use powdered or granular adsorbents to adsorb moisture have been used for a long time, but mechanically they are not as complete as the electric refrigerators mentioned above. The situation is such that various improvements are required.

In view of these points, the present invention has been developed to create an air system that can control indoor temperature and humidity by utilizing a small amount of electricity and natural heat such as solar heat, without using a special sealed structure or adsorbent conveying device. The present invention provides a harmonizer, and embodiments of the present invention will be described below with reference to the drawings.

In the figure, +11121 is a fluidized bed of hygroscopic powder (hereinafter referred to as adsorbent) such as 1 spheroidal silica gel or molecular sieve, and (1) is the adsorbent flowing down by gravity and the air pipe (3) below. 12) is a regeneration bed that removes moisture absorbed by the adsorbent by combining heated air flowing in from the 12), a dehumidification bed that allows the adsorbent to absorb moisture from the air flowing through the whale fluidized bed circle. , (4j
is a radiator that dissipates heat from the mixed flow of adsorbent and air flowing out from the dehumidifying bed (2).

(51 is a cyclone type separation device that separates the adsorbent from the mixed flow after heat dissipation, and causes the air to flow toward the indoor side (R) and the adsorbent to flow down to the hopper (6); these regeneration beds (1),
The dehumidification bed (21) and the separation device (51 are the dehumidifier and/or
Alternatively, they are connected by a conduit (7) through which air can flow, forming a circulation cycle of the adsorbent using an air flow.

Thus, the number of fluidized beds forming the dehumidifying bed 12+ is two, for example.

It has a multi-stage structure divided by wire mesh f8J (81...).

The rising air agitates the adsorbent and sequentially transports it to the upper stage, while the air and the moisture absorbent come into contact with each other at the same time. In addition, the regeneration bed 11) has a dispersion plate +91. +9 to... and the downstream pipe (1 (1, ati...
・The adsorbent falling from the hopper (6) by gravity is spread over one dispersion plate (9).

Moisture is released into the heated air rising through the small hole a11, while the flow pipe G (1) that opens near the dispersion plate (9) falls to the next dispersion plate (91), where it releases moisture in the same way as the upper stage. It has a structure in which the heated air is emitted and falls to the dispersion plate of the next stage...For example, the heated air supplied to this regeneration bed lit is Pump (141) from thermal storage 1c131 where heat is stored
Outdoors (0
The air heated to approximately 100°C is used through the air supplied from the regeneration bed +11, while the humid air flowing out from the regeneration bed +11 still has a temperature of approximately 80°C, so a heat pipe is used. After preheating the outdoor air flowing into the gas-liquid heat exchanger σ9 by the heat recovery device used (161), the outdoor air (0
) is exhausted.

On the other hand, WP'1 (empty RJ 51'l air ha, ventilation 1!I

This is a mixed flow with the adsorbent No. 011.

When the heat of the dry air with a high treetop temperature obtained in this way is dissipated to about 29℃ using a heat pipe type radiator (4), the air has a humidity of about 2011℃, so only the moisture absorbent is separated. When removed by the device (51), dry air is obtained.0 seconds is a humidifier that further lowers the temperature of this air and supplies it indoors. Due to the latent heat of vaporization used when water vaporizes, air with a temperature of approximately 18°C and humidity of 701g can be returned to the room.

(19 is an example of the extralayer air supply duct that supplies the above-mentioned regeneration bed (1), and in order to operate the circulation cycle of the adsorbent as shown in the example numerical values, it is heated at 35℃ and humidity of 50g6. After inhaling the outdoor air with the air blower m■, the temperature is lowered by the humidifier Qυ (approximately 25 tJ).This helps the heat dissipation in the radiator (4), and at the same time, the air heated in this way is heated again. Heat recovery device a8. Gas-liquid heat exchanger fi9
It may be supplied to the regeneration bed 11+ through the air outlet, or it may be directly discharged outdoors from the exhaust port.

The air temperature and humidity shown in the above explanation are theoretical values as a guideline for how the circulation cycle of the adsorbent that constitutes the air conditioner of the present invention functions, and in actual operation. Since indoor air temperature conditions and outdoor air conditions also change from moment to moment, the temperature of heated air supplied to regeneration floor +11, the air volume of blower αD, and the outdoor air distributed to radiator (4) are adjusted according to these changes. By controlling the amount of air, temperature, darkness, and amount of humidification by the ASEU humidifier, air adjusted to the required temperature and humidity is supplied to the room (twice a month).

In addition, when the air conditioner of the present invention is used for heating, the connection of the duct (I2) is changed so that the indoor air is directly heated by the gas-liquid heat exchanger 09 and recirculated to the room (R). Yes, no adsorbent is used.

As described above, in the air conditioner according to the present invention, when direct air conditioning is performed using the adsorbent in the fluidized bed, the flow path C of the circulation cycle from the regeneration bed outlet to the adsorbent separation device outlet is continuous. In this way, the temperature and humidity of the indoor air can be adjusted while circulating the adsorbent using the flow of indoor air. No equipment or control device is required, and therefore an air conditioner with simplified maintenance and service can be obtained.

In addition, the circulation cycle of the adsorbent is an open structure in which it comes into direct contact with empty indoor air, and solar heat, other natural heat, or waste heat from factories can be used as a heat source, reducing energy consumption. A more efficient air conditioner can be obtained.
