Description

  The present invention reduces the air conditioning load of heating and cooling by using ground water of a substantially constant temperature that is pumped from the basement in factories and office buildings designed to circulate room air, and circulates room air. The present invention relates to an air conditioning and cleaning device that performs heating, cooling, cleaning, humidity control, and the like of a system.

  Conventionally, along with high heat insulation and high airtightness of buildings, air circulation type air purification and air conditioning devices have been developed.For example, by providing an exhaust port in a common part and forming an intake port in an individual part, A gentle air flow from the intake port to the exhaust port is generated in the building through the power of the ventilator. By such air circulation, indoor air can be adjusted at all times.

In such an air circulation system, indoor air-conditioning and heating are performed using a mechanical air-conditioning device such as an air conditioner or a heater, and the following techniques have been proposed for energy saving of air-conditioning and heating. .
For example, a house using geothermal heat, which is natural energy, has been proposed (see, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2-89935)). Houses that use such geothermal heat have a constant underground temperature of about 15 degrees Celsius regardless of summer or winter. After heating or cooling the air with a heat exchange pipe embedded in the ground, The air conditioning load of heating and cooling is reduced by circulating the room.

In addition, an air circulation system has been proposed that uses natural energy such as groundwater and geothermal heat as a heat source to reduce the amount of energy consumed for air conditioning.
For example, an air conditioning system using a natural force of a building described in Patent Document 2 (Japanese Patent Laid-Open No. 2000-97586) includes a heat source facility (heat pump) of an air conditioner embedded in a underground pipe serving as a heat exchanger and installed on the ground. It is configured to circulate water between pipes. In the ground where underground pipes are buried, the temperature is maintained at around 15 ° C throughout the year, indoor air is cooled via underground pipes in summer, and indoor air is heated in winter. .

Moreover, the indoor air circulated through the building contains harmful components such as dust, smoke, and offensive odor, and many inventions and devices have been made as cleaning devices for removing these.
For example, as a gas-liquid contact type, Patent Document 3 (Japanese Patent Laid-Open No. 2000-225310) includes a blower at the top, and a metal filter, a perforated plate plate, and a water storage tank in that order approximately horizontally below There is disclosed an air circulation cleaning device that is disposed and controlled to release water sucked from the water storage tank via a water pump between a metal filter and a perforated plate plate.

However, in the conventional geothermal utilization air conditioning system, since underground pipes buried in the ground are used as heat exchangers, it is difficult to effectively arrange a heat exchange surface with air in the equipment. There was a problem that the heat exchange efficiency between geothermal and water was poor.
It is also possible to circulate more water and improve thermal efficiency by burying pipes deep in the ground or using large diameter pipes, but it is necessary to circulate water with a large capacity pump. As a result, there is a disadvantage that the effect of reducing energy consumption is reduced.

  Further, as shown in Patent Document 3, in the method of cleaning by bringing water into contact with the air to be cleaned through the perforated plate plate, since the surface area of the water droplet brought into contact with the air to be cleaned is relatively small, However, there is a drawback that dust, smoke, and odor cannot be completely removed from the gas sucked in.

  The present invention has been made to solve the above-described conventional problems, and in buildings and the like designed to circulate indoor air, heating and cooling are performed using ground water having a substantially constant temperature that is pumped from the underground. An object of the present invention is to provide an air conditioning and cleaning device that reduces the air conditioning load of the indoor air circulation system and performs heating, cooling, purification, humidity control, and the like of the indoor air circulation system.
