Description

Heat exchange module with excellent efficiency provided in heat exchange ventilation system {HEAT EXCHANGE MODULE WITH EXCELLENT EFFICIENCY PROVIDED IN HEAT EXCHANGE VENTILAION SYSTEM}

The present invention relates to a heat exchange module with excellent efficiency provided in a heat exchange ventilation system. More specifically, it relates to a heat exchange module that is installed in various buildings, etc. and can be implemented between indoor and outdoor spaces to prevent air flowing in and out from various directions from mixing. It relates to a heat exchange module with excellent efficiency that is provided in a heat exchange ventilation system that not only has a structure that not only allows ventilation, purification, and heat exchange in various directions, but can secure sufficient efficiency.

In general, with the recent rapid urbanization and industrialization progressing, industrial facilities and traffic volume are increasing as the population and scope of economic activities in cities expand, and air pollution levels are worsening.

Meanwhile, as urban centers develop and living standards rise, most people spend 80-90% of their time in indoor spaces such as offices, homes, and schools, and indoor air quality is an important factor in determining quality of life. It has become established as a standard, and in particular, as appropriate ventilation is required to maintain clean indoor air quality, ventilation systems installed in buildings are being legislated and made essential.

Furthermore, as contagious respiratory diseases caused by viruses such as COVID-19 have recently become widespread around the world, ventilation of the air in indoor spaces has become more and more important.

Meanwhile, the ventilation system installed in a building like this has the function of recovering heat energy when air circulates between indoor and outdoor spaces in order to save heating or cooling energy.

For example, if the outside temperature (temperature of the outdoor space) in summer is 35℃ and the indoor temperature (temperature of the indoor space) when the air conditioner is in operation is 20℃, a temperature difference of 15℃ occurs between the indoor space and the outdoor space. , In the case of ventilation performed without heat exchange due to this temperature difference, cold air from the indoor space is discharged to the outdoor space, and hot air from the outdoor space flows into the indoor space, resulting in a significant loss of heat energy due to cooling.

Due to the above problem of heat energy loss due to ventilation, a typical ventilation system uses a heat exchange medium made of a material with high thermal conductivity between the air from the indoor space being discharged and the air from the incoming outdoor space, and the air flowing in from the indoor space is It includes a heat exchange module that provides an environment in which heat exchange can occur without mixing the outflowing air.

Accordingly, the importance of heat exchange modules is increasing as a way to increase energy efficiency in ventilation systems where heat exchange is performed, and the weight and heat exchange efficiency of these heat exchange modules play an important role.

As a prior art for a ventilation system in which heat exchange is performed in this way, the invention titled 'Heat Exchange Ventilation System' under application number 10-2018-0070964 has been disclosed.

It includes a recirculation damper provided on the panel to selectively communicate with the recirculation passage and the outdoor air supply space, and an internal filtering module consisting of a filter means for filtering indoor air flowing into the recirculation passage.

The partition panel is mounted in such a way that both ends are respectively inserted into opposing side walls of the case, and a ventilation hole is formed in the partition panel to allow the internal air discharge space within the case to communicate with the recirculation passage.

The filter means consists of a pre-filter and a main filter arranged in close contact with the pre-filter, and the main filter is a HEPA filter with a fine particle collection function or a combination filter with a fine particle collection function and a deodorization function. is used.

In more detail, an outside air intake port and an outside air discharge port are provided on the outdoor side, an inside air intake port and an outside air supply port are provided on the inside side, an outside air intake space communicating with the outside air intake port, and an outside air intake space communicating with the inside exhaust port. A case comprising an internal exhaust space, an internal suction space in communication with the internal suction port, and an external air supply space in communication with the external air supply port, a heat exchanger provided in the case, and suction of outdoor air into the case, A suction blower that supplies indoor air, an exhaust blower that sucks indoor air into the case and discharges it to the outdoor side, and is installed below the heat exchanger in the case so that the internal intake space and internal exhaust space communicate without passing through the heat exchanger. A bypass cover constituting a bypass passage, a bypass damper that selectively communicates the internal suction port and the bypass passage, and a bypass damper that is mounted in the case and divides a portion of the internal space of the case to form a recirculation passage. It includes a partition panel, a recirculation damper provided on the partition panel to selectively communicate with the recirculation passage and the outdoor air supply space, and an internal filtering module consisting of a filter means for filtering indoor air flowing into the recirculation passage. , Through this configuration, the prior art allows selective use of the general ventilation mode, bypass ventilation mode, and recirculation mode, and also improves convenience of use because the inconvenience of replacing the heat exchanger and filter unit when operating the recirculation mode can be avoided. There is an advantage to improving.

Meanwhile, the heat exchanger (heat exchange module) as also mentioned in the prior art is used to ensure that mutual heat exchange occurs while the air in the indoor space and the air in the outdoor space are distributed in separate spaces so that they do not mix, and is usually shown in Figure 2. As shown in the drawing showing the general form of the heat exchanger, it is shaped like a rectangular parallelepiped and flows only in the direction facing each other so that it flows in a perpendicular direction. It is made of a metal material with high thermal conductivity, so that the indoor air with a temperature difference Ensure heat exchange occurs without mixing with outdoor air.

Due to these structural characteristics, conventional heat exchangers (heat exchange modules) have a considerable volume, and in particular, as a large amount of metal materials with high thermal conductivity are used for heat exchange, there is a problem in that the weight of the heat exchanger itself becomes relatively heavy. .

For this reason, the weight and volume of the heat exchanger are very important factors in that the heat exchanger is installed in a heat exchange ventilation system that is installed in a manner that hangs from the interior space of the ceiling. In particular, the weight of the heat exchanger is an important factor in the heat exchange ventilation system. Therefore, a heat exchanger that is relatively lightweight and has high heat exchange efficiency is required for the installation and maintenance of heat exchange ventilation systems.
