Description

Facility house heating boiler system {Facilities house heating boiler system}

The present invention relates to a heating boiler system of a facility house used to maintain an appropriate temperature in a facility house where vegetables or flowers are grown. It relates to a heating boiler system for a facility house that can improve economic efficiency by significantly reducing the maintenance cost required for heating a greenhouse by improving heat exchange efficiency through a plurality of possible individual boilers.

In general, as a type of heating device, a boiler heats water or steam using combustion heat generated when fuel is burned, and the heated water or steam circulates along a predetermined path and exchanges heat with surrounding walls or air. It is a device configured to repeat the process of heating the indoor space with a circulator and then heating it again.

Such boilers are classified into electric boilers, oil boilers, gas boilers, briquette boilers, etc. according to the type of fuel used, and are classified into standing boilers or furnace boilers, etc., depending on the type of installation, Depending on the circulation method of the heated water, it is classified into a natural circulation type water tube boiler or a forced circulation type water tube boiler.

In addition, in a facility house such as a plastic house installed for cultivating various crops such as flowers and various vegetables in winter, the installation cost and fuel cost are relatively low, so the briquette boiler is widely used.

However, since such a conventional briquette boiler has a standing structure in which the furnace in which the briquettes are stored and burned is erected and installed, it is very inconvenient to replace the briquettes, as well as using a plastic house for flowers, etc. In the case of cultivating briquettes, there is a problem that it takes a lot of time to replace the briquettes because the exchange amount of briquettes reaches several tens to hundreds at a time.

On the other hand, conventional electric boilers are made in a manner in which the water passing through the circulation pipe installed inside the boiler container is heated by applying power while the heating wire is installed inside the boiler container, and in the case of gas or oil boilers, gas or It is made by igniting the oil to heat the water passing through the circulation pipe inside the boiler vessel.

However, in the case of the electric boiler made as described above, although combustion gas is not generated or odor is generated, there is a problem in that the operation cost is very high because electricity must be supplied every time the boiler is operated.

In addition, in the case of a gas boiler or oil boiler, since gas or oil is consumed every time the boiler is operated, operating costs are high. There is a serious problem that

In order to improve the problems of such a boiler apparatus for a facility house, "a device for reducing heating costs for a facility house" is disclosed in Korean Utility Model Registration No. 20-0223179. This heating cost saving device uses groundwater (hot spring water) as a heat source, and when hot water heated from a hot water boiler to supply water passes through an air fin type or radiator type heat exchange coil through a hot water storage tank, It has a structure that supplies warm air to the inside of the facility house.

In such a heating device, when the blower is simply driven by the temperature in the house in a state where the temperature of the fan coil unit passing through the heat exchange coil is not sufficiently heated, the temperature of the blown air is different from the temperature in the facility house (the temperature of the blown air When the temperature is lower than the temperature in the facility house), the crop growth around the blower is delayed, so there is a problem that the harvest time varies. In addition, since heat exchange is performed in a specific area within the facility house by the radiator or fan coil unit, there is a problem in that the temperature deviation inside the facility house is relatively large.

In addition, as a recent technology, Korean Patent Laid-Open Publication No. 10-2018-0115203 "Improved heating apparatus for a greenhouse" is disclosed. This conventional technique improves heating efficiency by exchanging heat between the heating water in the heating water supply line and the heating water in the heating water recovery line by a solid block provided to solidify to surround the heating water supply line and the heating water recovery line. A technique for reducing heating costs is disclosed.

However, this conventional technique is not only very complicated in its structure, but also it is not possible to selectively utilize fuel because it uses a briquette boiler, and it is very inconvenient to use because it takes time to ignite, and because briquettes are used as fuel. There was a problem such as damage to facility crops due to the generation of fine dust scattered during the handling of briquettes.
