Description

[Detailed explanation of the invention] This invention is designed to display information on the front panel of the air conditioner installed indoors so that the amount of heat actually recovered during operation of the air conditioning ventilation system can be known in detail. The present invention relates to an air conditioning ventilation system in which the device is installed.

Figure 1 is an external view of the main body of a conventional conditioner installed indoors in an air conditioning ventilation system.The front panel 1 is only equipped with an operation indicator lamp 2, and the amount of heat recovered during operation cannot be known at all. This caused some inconvenience in terms of operation management.

This invention was devised to compensate for such inconvenience, and one embodiment of this invention will be described below. In other words, in Fig. 2, a temperature display device 4 is installed at the front lower end of the front panel in order to know the amount of recovered heat.
In the figure, 1 is a similar front panel, 2 is an operation display device consisting of strong, medium, and low indicator lamps, etc., 3 is the main body of the air conditioning ventilation system installed indoors, and 4 5 is a supply air temperature display device that displays the air temperature in response to a temperature signal from a temperature sensor (not shown) provided in the indoor supply air passage in the main body 3 of the conditioner; This is an exhaust temperature display device that displays the air temperature in response to a temperature signal from a temperature sensor (not shown) provided in an exhaust air passage from a room.

With this configuration, the temperature of the exhaust air from the room and the temperature of the air supplied to the room can be detected at a glance, so by comparing both, it is possible to determine the actual state of thermal energy recovery during operation. You can know.

Further, FIG. 3 shows another embodiment of the embodiment shown in FIG. 2, which is further provided with an outside air temperature display device 6 that also displays the temperature of the outdoor air.

Above, we have explained the case where the temperature display devices for the air supplied to the room and the air discharged from the room are installed in parallel on the main body of the conditioner. By providing a humidity sensor in each of the exhaust air passages and providing a supply air humidity display device and an exhaust air humidity display device based on signals from these sensors together with the temperature display device, it is possible to know the amount of recovered heat more accurately.

Furthermore, by processing the signals from the temperature and humidity sensors for the supply air and exhaust air using a microcomputer, etc., the thermal energy display converts and displays the temperature difference and humidity difference between the supply air and exhaust air as an amount of energy. If a device is installed, it will be possible to detect the heat more accurately if it has the amount of recovered heat.

In addition, each of the above-mentioned display devices does not necessarily need to be attached to the front panel of the harmonizer main body as in the illustrated embodiment, and it is of course possible to provide them, for example, on the remote control section of the harmonizer main body.

Since the air conditioning ventilation system of this invention is configured as described above, it is possible to detect and confirm at a glance the state of thermal energy recovery during operation, which was conventionally only done intuitively, thereby improving operational efficiency. This has the advantage that suitability can be easily determined.
