ため、一般に風路抵抗が大きく、換気風量が不十
分であることも問題点の一つになつている。 These heat exchangers use heat conduction and heat storage mechanisms,
Since it is a mechanism that transfers heat from the high-temperature airflow side to the low-temperature airflow side, the heat exchange efficiency of conventional air conditioning ventilation equipment using these is 60 to 70%. It needs to be large. In addition, in terms of functionality, in the case of heat exchange ventilation, those using a total heat exchanger have a single function of total heat exchange ventilation, and those using a sensible heat exchanger have a
Only the independent function of sensible heat exchange ventilation can be performed. In addition, in order to perform the non-heat exchange simultaneous supply and discharge function, in the case of a rotary heat exchanger, it is only necessary to stop the rotation of the heat exchanger, but in the case of a stationary heat exchanger, it is sufficient to stop the rotation of the heat exchanger. In this case, a bypass damper for the heat exchanger is required. In addition, it does not have any other functions other than ventilation, such as heating and cooling, so it is necessary to install a separate heating and cooling device to perform heating and cooling. on the other hand,
Even if a conventional air conditioner/heater were to be equipped with an air conditioning/ventilation function, it would be necessary to incorporate a heat exchanger for air conditioning/ventilation, resulting in a large device. In addition, because conventional air conditioning ventilation systems use air-to-air heat exchangers as described above, they generally have large air path resistance and insufficient ventilation air volume, which is another problem. .

The heat pump transfers heat from the airflow on the high temperature side that is in contact with the heat exchanger to the airflow on the low temperature side that is in contact with the heat exchanger on the heat radiation side of the heat pump circuit. Compared to heat exchange methods that transfer heat by , highly efficient heat exchange is possible. In addition, the conventional stationary plate type,
Instead of an air-to-air heat exchanger like the heat storage rotary type, we use a gas-to-liquid heat exchanger that uses refrigerant and has low air path resistance, so it is smaller than conventional models and has a large ventilation air volume. It can be taken.

る。 Further, in the circuit of the heat pump, a mechanism for moving condensed water generated on the surface of a heat exchanger that exchanges heat with the airflow into the other airflow, or
A mechanism for moving the condensed water to the leeward side of the airflow exchanging heat with the heat exchanger from the heat exchanger and evaporating it again into the airflow, or a mechanism for moving the condensed water and the two mechanisms and the condensation water to the outside of both the airflows. Since it has a moving mechanism, the air conditioning ventilation system of the present invention using the heat pump not only has the functions of total heat exchange ventilation and sensible heat exchange ventilation, but also has the functions of the heat pump. By stopping and ventilating, simultaneous supply and exhaust ventilation without heat exchange is possible. On the other hand, there is a built-in damper so that when the operation is performed, an indoor air circulation channel is formed at the same time as the indoor air exhaust channel is blocked, and an outdoor air circulation channel is formed at the same time as the outdoor air supply channel is blocked. , heating and cooling can be achieved by operating the damper.

Demonstrates advantages in total installation space, construction costs, and costs.

替が容易に出来る。(First Example) In the case of air conditioning ventilation during indoor heating In the case of air conditioning ventilation during indoor heating, the heat exchanger 19 is replaced with the evaporator and the heat exchanger 2 is
Use 0 as a condenser for ventilation. In this case, sensible heat in the exhaust stream 24 of indoor air is transferred from the heat exchanger 19 into the refrigerant, carried to the heat exchanger 20, and transferred into the supply air stream 25 of outdoor air. Furthermore, in this case,
Collect the condensed water generated on the surface of the heat exchanger 19,
Since a mechanism is added to introduce the outdoor air into the supply air flow 25, if it is introduced into this supply air flow 25 and evaporated, the heat pump becomes a total heat exchanger, and if it is not introduced into this supply air flow, sensible heat is generated. Since it is an exchanger, this device can easily switch between total heat exchange ventilation and sensible heat exchange ventilation.

In this case, sensible heat in the outdoor air supply stream 25 is similarly transferred via the refrigerant into the indoor air exhaust stream 24. In this case as well, as in the previous case,
The condensed water on the surface of the heat exchanger 20 is removed from the heat exchanger 2
If the air is introduced into the supply air stream 24 of the outdoor air after passing through 0 and evaporated, this device will perform a total heat exchange ventilation function, and if it is not introduced into the above air flow, this device will perform a sensible heat exchange ventilation function. Therefore, this device can easily switch between total heat exchange ventilation and sensible heat exchange ventilation.
