Abstract

PURPOSE:To provide clear and highly efficient humidification, by a method wherein a humidifier is disposed in an air passage for bypass which bypasses a cooler. CONSTITUTION:Air fed to a cooler 1 by means of a blower 2 is cooled and dehumidified by means of the cooler 1 and discharged. Meanwhile, a part of air fed by the blower 2 bypasses the cooler 1 and is fed to a moistening device 6. In this case, water fed to a hollow porous member 7 is heated by a heater 9 to produce steam which flows out from the humidifier 6 to a vent passage A through the pores of a porous sheet 7b, and flows out togetherwith air fed to the vent passage A. Since air bypassed (not humidified by) the cooler is sent to the humidifier, humidification efficiency is enhanced. In addition, since the humidifier consists of hydrophobic porous sheets which admit vapor but not water, CaCO3 in the water will not pass the pores.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a refrigeration system having a humidifier.

(Prior Art) In order to maintain the freshness of food, humidifiers have conventionally been provided inside prefabricated refrigerators and the like, and the humidifiers commonly used are ultrasonic type or centrifugal type.

[Ll that the invention tries to solve! Therefore, it has the following drawbacks. That is, CaCO5 in the tap water turned into white powder and adhered to the food, or the low-temperature air (-1 to -5°C) inside the refrigerator caused water particles to turn into snow-like particles and adhere to the food.

Furthermore, when a humidifier using the hydrophobic porous sheet described in the present invention is installed at the inlet or outlet airflow of the evaporator of a refrigeration system, the humidified air is dehumidified by the evaporator in the former case, and the humidified air is dehumidified in the latter case. In this case, the air cooled by the evaporator is sent to the humidifier, which has the disadvantage of poor humidification efficiency.

This invention was made to solve the above-mentioned problems, and an object of the invention is to obtain a refrigeration system that is clean and enables highly efficient humidification.

[Means to solve the problem]

A cooler for exchanging heat between a cooling medium and the air to be cooled, a blower for supplying the air to be cooled to the cooler, a front plate portion having an air suction port for introducing the air to be cooled, and cooling by the cooler. a rear plate section having an air outlet section for discharging the air; and peripheral wall plates such as a bottom plate section, left and right side panels, and a top plate section surrounding the cooler and forming an air passage through the cooler. and a hollow porous member made of a hydrophobic porous sheet having pores that do not allow water to pass through but allow steam to pass through, and water is supplied to the inside and vaporized. A humidifier that heats the humidified air by impregnating the humidified air through the pores of the hydrophobic porous sheet, wherein the humidifier is located on the windward side of the cooler and provided on the peripheral wall plate. The above object is achieved by constructing a refrigeration system by providing a bypass air passage having an inlet portion and bypassing the cooler, and arranging the humidifier in the bypass air passage.

[Effect]

Freezing in this invention! In position a, the humidification efficiency can be increased by blowing air that has bypassed the cooler, that is, air that has not been cooled by the cooler, to the humidifier.

In addition, since the humidifier is made of a hydrophobic porous sheet with pores that allow steam to pass through but not water, CaC in the water
o5 does not pass through the pores and therefore does not dissipate into the humidified air.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, (A) is a cooler unit main body connected to a refrigerator or the like. (1) is a cooler, which is composed of plate fins (1a) arranged in parallel with each other and a cooling coil (lb) that passes through the plate fins (1a). As the medium evaporates, the air cools.

(2) is a blower for blowing air to the cooler +11;
(3) is an outer box, which includes a front plate part (3a) having an air suction port (3a+) for introducing the air to be cooled, and an air outlet part (3a) for discharging the air cooled by the cooler +11.
b+); and the cooler (1).
It is composed of peripheral wall plate parts such as a bottom plate part (3d), left and right side plate parts (3e), and a top plate part (not shown), which surround the cooler +11 and form an air passage (3C) passing through the cooler +11. It is something. (6) is a humidifier disposed within the bypass air path (4).

Figure 2 shows the structure of the humidifier (6), and (7) is a hydrophobic porous sheet that allows water vapor to pass through freely but does not allow water to pass through (7b) as shown in Figure 3. It is a hollow porous member formed into a rectangular shape by gluing or heat-sealing.
Both ends (7a) have water inlets (7C) communicating with the hollow part (7C).
6a) and a drainage port (6b). (8) is a wavy spacer rolled up along with the hollow porous member (7) to form a ventilation path (A).

(9) is a heater for heating the water supplied to the hollow porous member (7). (7) and the wavy spacer (8) are wound around the core member OI to form a humidifier (6).

Next, the operation will be explained. The air supplied to the cooler il+ by the blower (2) is cooled and dehumidified by the cooler (1), and then blown out. A part of the air supplied by the blower (2) bypasses the cooler 11) and is supplied to the humidifier (6). At this time, the hollow porous member (7)
The water supplied is heated by the heater (9) and becomes steam from the pores of the porous sheet (7b), and flows through the ventilation path (A).
) flows out of the humidifier (6) and flows out together with the air supplied to the ventilation path (A).

〔Effect of the invention〕

A cooler for exchanging heat between a cooling medium and the air to be cooled, a blower for supplying the air to be cooled to the cooler, a front plate portion having an air suction port for introducing the air to be cooled, and cooling by the cooler. a rear plate section having an air outlet section for discharging the air; and peripheral wall plates such as a bottom plate section, left and right side panels, and a top plate section surrounding the cooler and forming an air passage through the cooler. and a hollow porous member made of a hydrophobic porous sheet having pores that do not allow water to pass through but allow steam to pass through, and water is supplied to the inside and vaporized. An inlet located on the windward side of the cooler and provided in the peripheral wall plate portion, in the humidifier that humidifies the humidified air by impregnating the humidified air through the pores of the hydrophobic porous sheet. Since the refrigeration system is constructed by providing a bypass air path that bypasses the cooler, and disposing the humidifier in the bypass air path,
Because it humidifies in the form of water vapor, it does not form like snow inside the refrigerator, and
CaCo5 in the water does not dissipate into the humidified air, and since the air that bypasses the cooler is supplied to the humidifier, the humidified air is not dehumidified by the cooler, and humidification is achieved. Efficiency is increased.
