Air purifying device with ventilating function

Abstract

PURPOSE: An air purification system with a ventilation function is provided to reduce the loss of constant pressure, to decrease noise and vibration, and to minimize the loss of energy by preventing the air from passing through a high-efficiency filter for a ventilation operation and the air from passing through a heat exchanger for an air purifying operation. CONSTITUTION: An air purification system with a ventilation function is composed of a body(10) comprising an inner space divided into supply and exhaust spaces(20,30), the supply space divided into upper and lower supply spaces(21,22), the exhaust space divided into upper and lower exhaust spaces(31,32), a first air purifying indoor suction port(41) and a second ventilation indoor suction port(42) formed in the lower side of the lower exhaust space, an indoor discharge port(43) disposed at the side of the lower air supply space, outdoor suction and discharge ports(45,46) arranged in the exhaust space, and a communicating hole(47) formed on a plate(13) for dividing the upper exhaust space and the upper supply space; a first damper(61) for opening and closing the second indoor suction port; a second damper(62) for opening and closing the outdoor and discharge suction ports; a third damper(63) for opening and closing the communicating hole; an exhaust fan(33) installed in the upper exhaust space to blow the air of the lower exhaust space to the upper exhaust space; a supply fan(23) mounted in the lower supply space to blow the air of the upper supply space to the lower supply space; an exhaust passage(34) formed in the body to communicate the upper exhaust space with the outdoor discharge port; a supply passage(24) divided and formed in the body near the exhaust passage to communicate the upper supply space with the outdoor suction port; a heat exchanger(51) disposed in the middle of the passage to exchange heat between the air of the supply and exhaust passages; an air purifying filter(52) arranged in the lower exhaust space to purify the air inserted through the first indoor suction port; and a ventilation filter(53) installed on the upper part of the heat exchanger of the supply passage.

Description

technical field [0001] The present invention relates to an air purification device with a ventilation function, more specifically, a flow channel for ventilation and a flow channel for air purification are formed separately, and each can obtain the best performance during the ventilation operation and the air purification operation. An air purification device with ventilation function with the best operating effect. Background technique [0002] Generally speaking, an air purification device is a device that makes the air fresh by filtering out dust and bacteria in the air. Recently, there have been not only the most basic air purification functions but also indoor air ventilation functions. A device that performs two functions with one device. [0003] The air purifier with ventilation function disclosed in JP-P-8-89566 communiqué belongs to this type of device which can not only purify air but also take ventilation. The air cleaner is equipped with an electric heat excha...

Problems solved by technology

[0005] However, the structure of this conventional air cleaner makes the air pass through the high-performance filter in vain not only during the air cleaning operation but also during the ventilation operation, thus shortening the use time of the filter. It is too long to shorten its life, and there is a disadvantage that the filter must be replaced frequently

[0006] In addition, the structure of the existing air cleaner makes the external air containing dust pass through the electric heat exchanger and then through the filter during the ventilation operation, so there is such a problem that dust is easily deposited in the electric heat exchanger and the heat transfer performance is reduced. question

[0007] In addition, the structure of the existing air cleaner is such that during the ventilation operation, the air from the outside also passes through the high-performance filter, and during the air purification operation, a part of the air also passes through the useless electric heat exchanger, thus making the air Static pressure loss due to increased flow resistance, in addition to causing noise and vibration, also brings about the problem of increased energy loss

[0008] In addition, in the existing air cleaner, since the indoor side suction port and the indoor side discharge port are formed adjacent to each other on the same surface of the main body, during the operation of ventilation and air purification, there is a problem of exhaustion into the indoor space. The phenomenon that the air reflows to the suction port side reduces the purification and ventilation effect of the indoor air.
