Embodiment 1

[0051] refer to Figure 1-8 , which is the first embodiment of the present invention. This embodiment provides a synergistic system device for low-grade heat in the exhaust air of a once-through air conditioner containing harmful media. By adjusting the air inlet valve 301 to adjust the gas flow rate, ensure that the harmful Substances will not flow into the indoor environment again to cause secondary pollution. At the same time, it also ensures that the amount of harmful media in the return air is within the processing capacity of the fresh air treatment section 101, avoiding the overload of the fresh air treatment section 101 and reducing energy consumption.

[0052] Specifically, the synergistic system device for the low-grade heat in the exhaust air containing harmful media of the DC air conditioner includes a fresh air supply pipeline 100 and an exhaust air pipeline 200. The fresh air supply pipeline 100 passes the external ambient air through the fresh air installed insid...

Embodiment 2

[0057] This is the second embodiment of the present invention. The difference from the previous embodiment is that the air intake valve 301 of this embodiment stretches the grille assembly 301a through the sliding fit between the opening and closing assembly 301b and the side wall of the air return port 300. Close, the opening and closing assembly 301b can be directly a group of plates with grooves or with sliders, with simple structure and convenient adjustment.

[0058] Specifically, the air intake valve 301 includes a grid assembly 301a and an opening and closing assembly 301b, which is the same as the previous embodiment. The set of connecting rods 301a-2, the grid plate 301a-1 and the connecting rods 301a-2 are sequentially movably connected and symmetrically connected to form multiple sets of ventilation areas M. The section of the ventilation area M is a parallelogram, and the opening and closing components 301b are symmetrically arranged on the grid The two ends of the...

Embodiment 3

[0060] refer to Figure 9 , 10 , which is the third embodiment of the present invention. The difference from the previous embodiment is that the air inlet valve 301 in this embodiment can evenly distribute the gas outflow points while controlling the gas flow rate, increasing the specific surface area , improve the gas treatment efficiency, so that the air inlet valve 301 can also be applied to the air volume control at the air inlet 401 of the processing part.

[0061] Specifically, a heat exchanger 400 is provided between the fresh air supply pipeline 100 and the exhaust pipeline 200, and the fresh air processing functional section 101 includes a fresh air filter section 101b, a fresh air heat exchange section 101c, and an air supply section 101d, and the air return port 300 Connected with the fresh air filter section 101b, the fresh air heat exchange section 101c is equipped with a heat exchanger 400, the air supply section 101d is provided with a blower unit 101a, the blo...

Abstract

The invention discloses a synergistic system device of low-grade heat in exhaust air containing harmful media of a direct air conditioner. The device comprises a fresh air supply pipeline and an exhaust pipeline, the fresh air supply pipeline communicates with indoor environment, fresh air is treated through a fresh air treatment function segment mounted in the fresh air supply pipeline and is fedinto indoor environment thorugh an air supply unit, the air in the indoor environment flows through the exhaust pipeline to flow out to the exterior, an air returning opening is arranged between theexhaust pipeline and the fresh air supply pipeline, and is provided with an air inlet valve which is in movable connection and can be opened and closed, the air inlet valve is adjusted to adjust the gas circulation a mount, it is ensured that the harmful media cannot flow into the indoor environment again to cause the secondary pollution, meanwhile, it is ensured that the harmful medium amount inreturned air is in the treatment capacity range of the fresh air treatment function segment, overload loads of the fresh air treatment function segment can be avoided, meanwhile, energy consumption isreduced, and the air inlet valve is simple in structure, convenient to adjust and suitable for multiple air amount control occasions.

Description

technical field [0001] The invention relates to the technical field of the exhaust system of a DC air conditioner, in particular to a synergistic system device for low-grade heat in the exhaust air of a DC air conditioner containing harmful media. Background technique [0002] The exhaust air of hospitals, laboratories, swimming pools, chemical plants, etc. often contains a large amount of harmful or unrecoverable gases. At the same time, these harmful gases contain a large amount of cold and heat that can be recycled. In these scenarios, the direct current method is often used The air conditioning unit is recycled, and the exhaust section uses the direct current method to pass the above-mentioned gas through the heat exchanger and then directly discharges it outside. The heat recovery section only recovers the cold and heat when the gas is discharged, and the airflow does not cross each other at all, so that the exhaust gas can be avoided. Waste of intercooler heat. [000...
