specific Embodiment approach 1
[0007] Specific Embodiment 1: As shown in Figure 1, the fresh air treatment unit with air supply heat recovery device described in this embodiment includes a fresh air treatment unit 1, a fresh air pipeline 2, a first air volume regulating valve F1, a second air volume Regulating valve F2, first connecting pipeline 10, second connecting pipeline 11 and third connecting pipeline 12, the fresh air processing unit 1 is composed of air supply section 1-1, humidifying section 1-5, table The cold section 1-2, the mixing section 1-3 and the exhaust air heat recovery device 1-4 are composed; the fresh air processing unit also includes a supply air heat recovery device 13; The two ends of the second connecting pipeline 11 communicate with the fresh air pipeline 2 and the exhaust air heat recovery device 1-4, and the two ends of the first connecting pipeline 10 communicate with the air supply heat recovery device 13 It communicates with the second connecting pipeline 11, the first air v...
specific Embodiment approach 2
[0008] Embodiment 2: As shown in FIG. 1 , the second connecting pipeline ( 11 ) in this embodiment is a right-angle elbow. Such setting facilitates the connection with the air-conditioning processing unit 1 . Other components and connections are the same as those in the first embodiment.
[0009] The working principle of the present invention is (in conjunction with Fig. 2 description): a part of outdoor fresh air enters into the air supply heat recovery device 13 (for air supply heat recovery) through the fresh air pipeline 2, and then passes through the first connecting pipeline 10 and the second The connecting pipeline 11 enters the exhaust air heat recovery device 1-4 of the air conditioning processing unit 1 (for exhaust air heat recovery); another part of outdoor fresh air enters the exhaust air heat recovery of the air conditioning processing unit 1 through the second connecting pipeline 11 1-4 (exhaust air heat recovery), then enters the mixing section 1-3 of the air ...
