Description

Total Heat Exchange Ventilator with Machine Room Separation Structure} The present invention relates to a heat exchange ventilation device, and more specifically, to a heat exchange ventilation device that is implemented in a convenient and highly reliable manner by providing a machine room separation structure that allows only the machine room portion to be slid down a certain distance relative to the main body without the need to disassemble components for cleaning or maintenance work inside the machine room where the condenser and evaporator are installed, while reducing the weight of the ventilation device and ensuring that the slide separation structure has sufficient support rigidity, and furthermore, by embedding the control circuit components inside the ventilation case instead of installing them outside the ventilation case, and by allowing the embedded control circuit components to be easily opened and accessed from the bottom of the ventilation case, thereby enabling inspection or maintenance without space constraints. A ventilation system is a ventilation facility that introduces fresh outside air and expels contaminated indoor air to the outside in residential spaces, such as homes or offices, in order to maintain or improve indoor air quality. A heat exchange ventilation system is a ventilation device that saves energy by exchanging the heat (hot and cold) of the air exhausted from the interior with the heat of the air entering from the exterior through a heat exchange element, and is also known as a 'waste heat recovery ventilation system'. As is well known in the prior art, including Patent Documents 1 to 4, a heat exchange ventilation device has an air inlet, an outdoor air inlet, an indoor supply port, and an outdoor exhaust port near the four corners of a ventilation case, and has a form in which air flow ducts are connected to these inlets. In addition, the ventilation case has a structure in which a heat exchanger, a supply fan, an exhaust fan, and dampers for opening and closing the inlets and air passages are installed. As is well known in the field of the prior art including Patent Documents 1 to 4, a heat exchanger is configured such that a plurality of liners are arranged with a gap in the vertical direction, and corrugated plate-shaped spacers that allow air to pass in only one direction are arranged in an alternating (crossing) direction on the upper and lower parts of each liner, so that indoor air and outdoor air pass through the upper and lower parts of the liner in a cross-sectional manner, thereby enabling heat exchange between the upper and lower air through the liner. In the past, including Patent Documents 1 to 4, heat exchange ventilation devices that include a refrigerant cycle device for cooling and heating to enable auxiliary cooling and heating in addition to the function of ventilation by passing indoor air and outdoor air through a heat exchanger are widely used. In the case of a heat exchange ventilation system equipped with a refrigerant cycle device, equipment for operating the refrigerant cycle (e.g., compressor, condenser, evaporator, various valves, etc.) is installed, and these are housed in a machine room, which is a space separated by a bulkhead from a heat exchange room containing a heat exchanger. This heat exchange ventilation system pre-exchanges heat between indoor air discharged from the room and outdoor air entering from the outside through a heat exchange element. Additionally, outdoor air entering the room after passing through the heat exchange element passes through a first heat exchanger (which acts as an evaporator during cooling and a condenser during heating) to exchange heat with the outdoor air, and indoor air discharged to the outside after passing through the heat exchange element passes through a second heat exchanger (which acts as a condenser during cooling and an evaporator during heating) to exchange heat with the indoor air. Furthermore, without operating the refrigerant cycle, indoor air is discharged to the outside and outdoor air is drawn into the room for ventilation, or only indoor air is passed through a filter to purify the indoor air. Therefore, through this process, indoor cooling, heating, ventilation, and air purification are possible. As such, when a refrigerant cycle device is provided in a heat exchange ventilation system to perform cooling and heating, condensation forms on the surfaces of the first and second heat exchangers or the blower fan module, for example, due to the temperature difference with the surrounding air. This moisture causes dust to accumulate on internal components such as heat exchangers and leads to the proliferation of bacteria or mold. Since the bacteria or mold proliferated in this way enter the room along with the air when the heat exchange ventilation system is restarted, they cause indoor contamination. Therefore, the heat exchange ventilation system needs to be cleaned periodically to mai
