Abstract

PURPOSE: A fan coil unit capable of easily being assembled is provided to prevent the degradation of air conditioning performance caused by an unstable external air flow as the external air flow is easily guided when the sucked external air is discharged via a discharging hole after heat exchange. CONSTITUTION: A fan coil unit capable of easily being assembled comprises a housing unit (100), a drain plate (200), a heat exchanger (400), and a blowing fan unit. The housing unit made of a shock absorbing material includes a guide unit guiding a fluid downwardly on the periphery of an inner wall. The drain plate temporarily stores the guided fluid made of a shock absorbing material and includes an intake grill (610). The heat exchanger exchanges the heat of external air flowing from the intake grill. A water inlet and a water outlet are connected to the heat exchanger and installed on the lateral side of the housing unit. A sub-water receiver is installed on the lateral side of the housing unit. The sub-water receives temporarily stores the water which is generated and dropped from the water inlet and the water outlet and discharges the same to outside.

The present invention relates to a fan coil unit that is easy to assemble, and more particularly, to a fan coil unit that is easy to assemble and prevents thermal insulation and noise, and prevents leakage of water.

In general, an air conditioner such as a ceiling air conditioner is installed on the ceiling of an indoor space, and the use and development of recent years has increased due to the advantage that the indoor space can be used more widely and the advantage of allowing the interior space to be more quickly harmonized. have. The ceiling air conditioner is provided with a blowing fan, a heat exchanger, and the like in an approximately hexahedral space.

Only one surface of the ceiling air conditioner is exposed to the outside, and thus a suction part for sucking air and a discharge part for discharging air exchanged with the heat exchanger are disposed on one surface. It is common to have one to four discharge parts.

The air conditioner as described above takes a large number of parts, there is a problem that the process for assembling the plurality of parts is increased, thereby increasing the production cost of the product.

In addition, while the number of assembly is increased due to a large number of parts, when the binding relationship between the parts is not precise, noise and trouble occurs frequently due to long-term operation.

In addition, when water leaks from the water pipe side connected to the heat exchanger side, the water leaks into the room through the ceiling.

In addition, although some heat insulating materials are used to provide heat insulating performance, the heat insulating material may not be insulated from each part, and thus, the overall heat insulating performance is deteriorated.

Next, the effect of the fan coil unit manufactured as described above will be described.

The housing 100 according to the present invention is formed of expanded polypropylene (EPP).

As a result, it has excellent heat resistance and exhibits excellent performance in heat-resistant packaging.

In addition, it is suitable for the packaging of products requiring precision due to the small change of dimension according to temperature. Compared with the existing buffer packaging material, it has excellent buffering resistance against repeated impact and energy absorption effect at high temperature range (-40 ~ 110 ℃).

Compared with the conventional cushioning packaging material, it can have similar buffering properties even with a high foaming foam, thereby reducing product cost and distribution cost due to light weight.

EPP protects the surface of products from vibrations and other obstacles during transport because they have the appropriate strength, flexibility and elasticity in a semi-rigid state.

Since it is an uncrosslinked foamed polypropylene, it is easy to process materials such as reuse of raw materials after regeneration and grinding, thus saving resources and saving energy.

Conventional buffer packaging materials are easily softened or dissolved in machine oil, grease, solvents, gasoline, etc., but EPP has excellent oil and chemical resistance, and is easy to package machine parts using machine oil or grease.

It is non-toxic and can be used as a food and vegetable container.

It can be used for low temperature packing below -30 ℃, transportation and packing used at high temperature.

Its low permeability and low thermal conductivity make it suitable for building materials and civil engineering.

EPP can be cut and sliced with a knife, slicer, handsaw and hot wire, and it is also very easy for secondary processing such as gluing, heat fusion, and press work.

Therefore, the housing 100 according to the present invention can solve the low thermal insulation and noise vibration generated in the conventional iron plate. In addition, the housing may protect heat emitted into the heat exchanger and block noise and vibration that affect the room.

By using the BLDC motor 510 according to the present invention, the low power factor, the increase in the current THD, the speed response and the controllability, which are generated in the control system of the fan filter unit for the conventional single-phase AC induction motor, It is possible to improve the same problem and to control the control system even at a remote location.

In addition, by using the auxiliary drip tray 700 according to the present invention, it is possible to prevent leakage of the coupling gap or condensate from the ceiling after connecting the water pipes.

In addition, by using the guide projection 110 according to the present invention, it is possible to smoothly distribute the air conditioning.

While specific embodiments of the fan coil unit have been described so far, it is obvious that various embodiments can be modified without departing from the scope of the present invention.
