Embodiment approach 1

[0105] Such as Figure 1 to Figure 5 As shown, the heat exchange type ventilator according to Embodiment 1 has an indoor side exhaust port 201 and an indoor side air supply port 202 on the indoor side of one side. In addition, on the other side, an exhaust connection port 203 and an air supply connection port 204 are provided, and a heat exchanger 205 for exchanging heat between the exhaust flow from the room and the supply flow from the outside is provided inside it, and the exhaust air flow forming the exhaust air flow is formed. The blower 206 is used for exhausting the air flow.

[0106] In addition, the heat exchange type ventilator has a ventilator unit 208 provided with an air supply blower 207 for forming a supply air flow. There is also a partition for separating the exhaust flow path 209 connected to the exhaust connection port 203 of the ventilation unit 208 and the supply flow path 210 connected to the air supply connection port 204 of the ventilation unit 208 Pl...

Embodiment approach 2

[0144] refer to Figure 6 ~ Figure 8 , Embodiment 2 of the present invention will be described.

[0145] Such as Figure 6 ~ Figure 8 As shown, the heat exchange type ventilator of Embodiment 2 exchanges heat between indoor high temperature air 301 and outdoor low temperature air 302 through blower 303 and heat exchange element 304 . In addition, this heat exchange type ventilator has a bypass air passage, and the bypass air passage is composed of the following parts: a heat exchange device part 305 for performing outdoor air supply and indoor exhaust; , the low-temperature air passage 307 arriving at the heat exchange machine part 305 from the low-temperature air inlet 306; the high-temperature air passage 309 arriving at the high-temperature air exhaust port 308 from the heat exchange machine part 305; and the low-temperature air passage 307 and the high-temperature air passage 309 The opening 311 on the partition plate 310. In addition, the low-temperature air passage 30...

Embodiment approach 3

[0160] refer to Figure 9 Embodiment 3 of the present invention will be described. exist Figure 9 In , the same symbols are used for the same components as those in Embodiments 1 and 2, and descriptions thereof are omitted.

[0161] Such as Figure 9 As shown, the structure formed is: a damper 314 for the low-temperature air intake port and a damper 315 for the high-temperature air exhaust port to change the openings of the low-temperature air intake port 306, the high-temperature air discharge port 308, and the opening 311. And among the dampers 316 for the opening of the partition plate, the two dampers are integrated and their operations are interlocked.

[0162] According to the above structure, the number of motors for driving the dampers 314, 315, and 316 can be reduced, resulting in space saving and cost reduction.

[0163] In addition, the damper 314 for the low-temperature air suction port, the damper 315 for the high-temperature air discharge port, and the dampe...

Abstract

The present invention provides a heat exchange type ventilator in which the size of a flow passage changing unit provided with a damper can be reduced. The ventilator includes a partition plate (211) partitioning an exhaust flow passage (209) from an intake flow passage (210), an exhaust damper receiver (213) having an exhaust opening (212), and an intake opening (214). The ventilator further includes a flow passage changing unit (222) having an intake damper receiver (215), an exhaust damper (216) opening and closing the exhaust opening (212), and an intake damper (217) opening and closing the intake opening (214). A damper side bent part (224) is provided in the exhaust damper (216) and the intake damper (217), and a receiving side bent part (223) is provided near the end parts of the exhaust damper receiver (213) and the intake damper receiver (215) along the damper side bent part (224).

Description

technical field [0001] The present invention relates to a heat exchange type ventilator used in low temperature regions, etc., and more particularly relates to a heat exchange type ventilator which prevents heat exchange elements from freezing. Background technique [0002] Conventionally, a heat exchange type ventilator is equipped with an antifreezing device of the ventilator (for example, Japanese Utility Model Publication No. Sho 62-17743). [0003] Below, refer to Figure 25 and Figure 26 , the anti-freezing device of such a ventilator will be described. Such as Figure 25 As shown, an exhaust flow path 102 and a supply flow path 103 are intersected inside the main body 101 . A heat exchanger 104 is arranged at these intersections. On the suction side of the main body 101, a casing 107 provided with a low-temperature flow path 105 and a high-temperature flow path 106 is disposed. A low-temperature channel inlet 108 and a high-temperature channel inlet 109 are provi...
