Description

[Detailed Description of the Invention] The present invention relates to an air conditioner equipped with an air washer device, which is designed to improve controllability and thermal economy of the air washer.

2. Description of the Related Art An air conditioner is known in which an air washer device is attached to the air conditioner for bringing spray droplets of hot water into contact with the air passing through the air conditioner, and the air is cleaned, heated, and humidified by the air washer device. Such air conditioners are relatively large in size and are often installed in factories and the like. Usually, the air washer installed in this air conditioner circulates hot water in a hot water tank and uses an external heat source to maintain the water temperature in the hot water tank. When using steam as an external heat source, insert a silencer (silenced steam discharge device for sucking steam directly into the water) into the hot water tank, and blow steam into the water from this silencer to release steam into the tank. It was common practice to heat the water.

However, with this method of blowing steam into the water in the tank, the entire amount of water in the tank is heated to a predetermined temperature before being sprayed with an air washer, which takes a long time to warm up, and also makes it difficult to reach the set temperature during operation. The poor followability made it difficult to precisely control the temperature of the supply air. Furthermore, since the overall water temperature in the hot water tank must be raised each time the air conditioner is started, a large amount of water vapor is required, which poses a thermoeconomic problem.

The present invention was made with the aim of solving such problems, and is an air conditioner equipped with an air washer device for heating and humidifying air, in which water sprinkled by the air washer device is circulated back to the air washer device. A circulating water pipe is formed, a circulating pump is interposed in the circulating water pipe, a steam pipe is connected to the water pipe of the circulating water pipe via a steam line mixer, a steam valve is interposed in the steam pipe, and , detecting either the temperature of the water flowing through the circulating water pipe or the temperature of the supply air obtained by the air conditioner, and adjusting the opening of the steam valve based on this temperature detection signal. The present invention provides an air conditioner with an air washer device.

EMBODIMENT OF THE INVENTION Below, the structure of the air conditioner with an air washer device of this invention will be specifically explained with reference to the embodiment shown in the drawings.

Figures 1 to 3 all show an air conditioner in which a roll filter 1, an eliminator 2, a cooling coil 3, an Erofin heater 4, and an air supply fan 5 are installed in a casing 6, and an air washer device according to the present invention is attached to the air conditioner. An example is shown.

In the embodiment shown in FIG. 1, a roll filter 1, a cooling coil 3, an Erofin heater 4, and an air supply fan 5 are installed in the order of air flow in the casing 6, and between the roll filter 1 and the cooling coil 3, The eliminator 2 is inserted into the air washer part 7 and its downstream side, and the tank 8 is placed below the air washer part 7 and the eliminator 2.
and the water tank 1 above the air washer section 7.
3 is installed. A filler 14 is installed in the air washer section 7, and water is sprayed onto the filler 14 from a water spray tank 13, where air and water come into gas-liquid contact. After the gas-liquid contact, the water is collected in the tank 8 below. In order to return the water in the tank 8 to the water sprinkling tank 13, a circulating water pipe 10 with a circulating pump 9 interposed therein is provided. A steam line mixer 1 is connected to the pipe on the discharge side of the circulation pump 9 of the circulating water pipe 10.
1 is inserted, and this steam line mixer 11
A steam pipe 18 is connected to. The steam line mixer 11 mixes the steam flow with respect to the water flow flowing inside the pipe while preventing the water flow from flowing back to the steam pipe side, and its structure itself is well known. A steam valve 12 is interposed in the steam pipe 18, and by adjusting the steam valve 12, the amount of steam supplied from the steam line mixer 11 to the circulating water in the circulating water pipe 10 is adjusted. The opening degree adjustment of the steam valve 12 is automatically performed based on a detection signal from a temperature sensor 15 that detects the water temperature in the water sprinkling tank 13.

The embodiment shown in FIG. 2 is a steam line mixer 1.
1 was inserted into the water pipe on the suction side of the circulation pump 9 in the circulating water pipe line 10, and the temperature sensor 15' was inserted into the pipe line of the circulating water pipe 10 on the discharge side of the circulation pump 9. This is an example of an apparatus of the present invention having the same configuration as the embodiment shown in the figure.

In the embodiment shown in FIG. 3, a capillary washer member 17 is installed in the air washer section 7, and water is sprayed onto the capillary washer member 17 from a plurality of spray nozzles 16.
A temperature sensor 19 for detecting the water temperature in the tank 8 and a temperature sensor 20 for detecting the air temperature after passing through the Erofin heater 4 are provided.
This is an example of the device of the present invention having substantially the same configuration as the embodiment shown in FIG. 1, except that the opening degree of the steam valve 12 is adjusted by the temperature detection signal 9 and/or 20. . Here, the capillary washer member 17 is made of a porous material plate that is breathable but capable of retaining water by capillary action.

According to the air conditioner with air washer device of the present invention having the above configuration, steam is directly blown in a controlled amount into the continuous flow of water in the circulating water pipe 10 by the circulation pump 9, which is different from the conventional one. This allows for more rational control than using a silencer to blow steam into the water in the hot water tank. In other words, if the entire amount of water in the hot water tank is heated to the required temperature and then circulated, it takes time to heat up the entire water, so it takes time to warm up, and the supply air temperature increases while the air conditioner is operating. When controlling the supply air temperature within the set range, there is a delay in tracking between the supply air temperature set value and the water temperature in the hot water tank, causing a problem in responsiveness, but in the case of this invention, it follows the indicated value from the temperature sensor. By controlling the opening of the steam valve 12, the necessary amount of steam is directly introduced into the water flow before watering, so the warm-up time is extremely short and the responsiveness is extremely high even when the air conditioner is in operation. Supply air temperature control can be achieved. Since only the required amount of steam is used to heat the water to the required hot water temperature at that time, thermal economy is achieved compared to the case where the entire amount of water in the tank is heated and circulated. Therefore, according to the present invention, the stated objectives are effectively achieved.
