Description

Technology Field

[0001] The present invention relates to a heat recovery type combined air conditioning system, and more specifically, to a heat recovery type combined air conditioning system capable of using an air conditioner equipped with a cooling and heating cycle and an air purification device equipped with a heat exchange element, and capable of cleaning and sterilizing the filters of the air conditioner and the air purification device. Background Technology

[0003] Generally, air purification devices for ventilating indoor air are designed to guide indoor air to the outside or outdoor air to the inside, and are installed in various facilities such as general houses and apartments, as well as schools, hospitals, kitchens, and subway stations.

[0004] In particular, among air purification devices, a heat recovery type air purification device is equipped with a heat exchanger inside the casing, and an outdoor air intake space for drawing in outdoor air, an outdoor air exhaust space for discharging indoor air to the outside, an indoor air exhaust space for discharging outdoor air towards the inside, and an indoor air intake space for drawing in indoor air are formed.

[0005] In addition, the above-mentioned heat exchanger is a tool for saving energy by enabling heat exchange between indoor air and outdoor air, and ventilation holes for intake and exhaust are formed in the outdoor air intake space, outdoor air exhaust space, indoor air exhaust space, and indoor air intake space of the air purification device to regulate the indoor space to a temperature, humidity, and airflow distribution suitable for human activity, and at the same time remove dust and other particles from the air.

[0006] In addition, a temperature control air conditioning unit, so-called an air conditioner, is installed indoors for heating and cooling the air; this air conditioner regulates the indoor temperature using a refrigerant through a heating and cooling cycle consisting of a compressor, expansion valve, condenser, and evaporator.

[0007] At this time, air conditioners are classified into integrated air conditioners, in which the cooling and heating cycle is manufactured as a single unit, and split-type air conditioners, in which they are manufactured separately into an indoor unit containing an evaporator and an outdoor unit containing other components of the cooling and heating cycle; they are further classified into floor-mounted types installed indoors and ceiling-mounted types installed on the ceiling.

[0008] In particular, ceiling-mounted air conditioners are installed on the ceiling of indoor spaces, and although their use and development have recently increased due to the advantages of utilizing indoor space more extensively and harmonizing the interior space more quickly, they have the disadvantage of significant energy waste because they are not equipped with heat exchange elements to exchange heat between indoor and outdoor air, or between outdoor and indoor air.

[0009] In addition, air purifiers equipped with heat exchange elements have the disadvantage of not being able to cool or heat the indoor space because they lack a cooling and heating cycle.

[0010] Therefore, it is time to make efforts to resolve the aforementioned disadvantages by using an air conditioner equipped with the above-mentioned heating and cooling cycle in combination with an air purification device equipped with a heat exchange element.

[0029] First, it should be noted that identical components or parts in the drawings are indicated by the same reference numerals whenever possible. Additionally, in describing the present invention, specific descriptions of related known functions or configurations are omitted to avoid obscuring the essence of the invention.

[0030] The heat recovery type composite air conditioning device (1000) of the present invention comprises a box-shaped casing (1100), and the casing (1100) is divided into a first space (1200) and a second space (1300) by a first partition (1110), and the first space (1200) is divided into a first space (1200) and a third space (1400) by a second partition (1120), wherein a first outdoor air intake (1310) is formed on one side of the first space (1200) and a first outdoor air discharge (1710) is formed on the other side, and a first blower fan (1700) is installed in the first outdoor air discharge (1710), and between the first outdoor air intake (1310) and the first blower fan A first dust collection filter (1600) is installed.

[0031] The interior of the third space (1400) is equipped with a heat exchange element (1401), and is divided by partitions into an outdoor air intake space (1411) equipped with a second outdoor air intake port (1410), an indoor air intake space (1421) equipped with an indoor air intake port (1420), an indoor air exhaust space (1431) equipped with an indoor air exhaust port (1430), and an outdoor air exhaust space (1441) equipped with a second outdoor air exhaust port (1440), wherein a second dust collection filter (1500) is disposed between the second outdoor air intake port (1410) and the heat exchange element (1401), and a second blower fan (1432) is provided in the indoor air exhaust space (1431) and the outdoor air exhaust space (1441). A third blower fan (1442) is installed in each case, and the first outdoor air outlet (1710) of the first space (1200) and the second outdoor air outlet (1440) of the second space (1300) are connected to the second space (1300), and a heating and cooling coil (1800) is built inside the second space (1300) so that air discharged from the first outdoor air outlet (1710) and the second outdoor air outlet (1440) passes through the heating and cooling coil and is then discharged through the integrated outdoor air outlet (1900) formed on one side of the second space (1300).

[0032] In addition, the present invention is configured such that the first outdoor air intake (1310), the second outdoor air intake (1410), and the indoor air intake (1420) each have dampers (1310a, 1410a, 1420a), and the dust automatic cleaning type filter means (2000) illustrated in FIG. 4 is each provided inside the dampers (1310a, 1410a) of the first outdoor air intake (1310) and the second outdoor air intake (1410), and the dust discharge pipe (2100) connected to one end of each dust automatic cleaning type filter means (2000) is connected to the indoor air discharge space (1431), and the dust discharge pipe (2100) is each configured to have a damper (2110) built inside.

[0033] It is preferable that the above-described automatic dust cleaning type filter means (2000) have a structure in which a brush (2010), which rotates by the driving of the filter (2020), shakes off dust accumulated on the filter (2030), and the dust shaken off in this way is discharged to the outside through the dust discharge port (2040). Of course, it is obvious that even if the automatic dust cleaning type filter means (2000) is not shown or described in the present invention, it is not limited to that structure as long as the operation of the blower is required.

[0034] Since the present invention is a structure that removes dust by applying a reverse airflow to the filter (2030) of the automatic dust cleaning type filter means (2000), to achieve this, first, the dampers (1310a, 1410a, 1420a) of the first outdoor air intake (1310), the second outdoor air intake (1410), and the indoor air intake (1420) are closed, and when the second blower (1432) is driven, a strong negative pressure is formed in the indoor air discharge space (1431), and indoor air flows in the opposite direction into the second space (1300) through the integrated outdoor air discharge port (1900), and then flows in again through the first outdoor air discharge port (1710) of the first space (1200) and the second outdoor air discharge port (1440) of the third space (1400), thereby removing the dust shaken off by the brush (2010) with a reverse airflow. As it is blown, it passes through the indoor air discharge space (1431) through the dust discharge pipe (2100) connected to the dust discharge port (2040) by strong suction pressure and is discharged to the outside through the indoor air discharge port (1430).

[0035] As a result, the filter (2030) of the automatic dust cleaning type filter means (2000) as well as the dust collection filters (1500, 1600) can be maintained in a cleaner filter state by the automatic dust cleaning type filter means (2000) for removing dust prior to the first dust collection filter (1600) and the second dust collection filter (1500).

[0036] In addition, the present invention allows for the sterilization of air flowing in from the outside through the first space (1200) and the third space (1400) by forming a sterilization means (3000) on one or both sides of the heating and cooling coil (1800) and on one or both sides of the first dust collection filter (1600) and the second dust collection filter (1500), thereby enabling the sterilization of the contaminated heating and cooling coil (1800) and simultaneously enabling the supply of air flowing in from the outside to the indoors in a clean state at all times.

[0037] In the present invention, all electrical driving means, namely each damper, blower fan, heating and cooling cycle device, dust automatic cleaning type filter means (2000), and sterilization means (3000), are controlled by a control unit (not shown), and the control unit controls the opening, closing, or driving of these parts according to a preset mode.

[0038] The control modes available by the above-mentioned control unit consist of a heat exchange ventilation mode, an indoor cooling or heating mode, a combined air conditioning mode that enables indoor cooling or heating while performing heat exchange ventilation, a filter cleaning mode, etc.

[0039] In the present invention, all dampers are opened and closed by driving a motor, and the driving of the motor is naturally carried out by a control unit, and the control unit is composed of a PC or a microprocessor, etc., and automatically controls all electrical driving means according to each mode set by a pre-installed program.
