Window type ventilation and purification heat exchange device

Abstract

The invention discloses a window type ventilation and purification heat exchange device. The window type ventilation and purification heat exchange device comprises a shell and further comprises a control system. The control system comprises a controller. A fresh air inlet and an exhaust air outlet are formed in the outdoor side of the shell. A fresh air outlet and an exhaust air inlet are formed in the indoor side of the shell. A partition plate is installed in the shell and divides the interior of the shell into an air inlet channel and an air exhaust channel. A minitype air supply centrifugal fan and a combined multi-layer filter screen are installed in the air inlet channel. A temperature and humidity sensor and a particulate matter mass concentration sensor are arranged at the position, close to the fresh air outlet, in the air inlet channel. A minitype air exhaust centrifugal fan is installed in the air exhaust channel. One channel of a heat exchanger is communicated with the air inlet channel, and the other channel of the heat exchanger is communicated with the air exhaust channel. Due to adoption of the double-fan design, one centrifugal fan supplies air into a room, the other centrifugal fan exhausts air out of the room, and a certain energy conservation effect can be achieved.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a window type ventilation and purification heat exchange device. Background technique [0002] Indoor air quality directly affects people's health and comfort. The sources and types of indoor pollutants are increasing day by day, and the airtightness of buildings is increasing, which makes it difficult for indoor pollutants to spread and increases the chances of people indoors coming into contact with pollutants. At this time, introducing fresh air into the room and exhausting indoor unclean air can effectively improve the indoor air quality. However, in a location with high population density and building density in the downtown area, the quality of fresh air is degraded due to vehicle exhaust, industrial pollution, garbage incineration, and road dust. If the concentration of pollutants in the outdoor air exceeds the control index of environmental parameters, in this environment Direc...

Problems solved by technology

Disadvantages of this design: 1) The negative ion generator will produce ozone, a small amount of ozone is harmless to the human body, but excessive ozone will combine with some organic matter to produce carcinogens; 2) The ionized air under the high pressure of the negative ion generator may decompose nitrogen group 3) Negative ion generators may cause static electric shocks, resulting in blackening of indoor walls; 4) When the outdoor wind environment changes, the design cannot effectively deal with 5) The design does not design heat preservation and noise reduction; 6) The airflow at the air outlet is a horizontal jet, and the airflow is not easy to reach people's breathing area

Disadvantages of this design: 1) The filter is equipped with three filters of coarse-effect filter, medium-efficiency filter and high-efficiency filter, and the flow channel resistance cannot be overcome by the cross-flow fan; 2) The air inlet is not designed with effective self-balancing measures ; 3) There is no effective thermal insulation and noise reduction measures designed in the flow channel; 4) The airflow at the air outlet is a horizontal jet, and the airflow is difficult to reach people's breathing area

Looking at the situation of the fresh air system at home and abroad in the past ten years, the technology of the fresh air system faces the following challenges: 1) energy consumption - the amount of fresh air entering the room directly affects the overall energy consumption of the building; 2) comfort - the amount of fresh air entering the room The fresh air system requires low noise and controlled airflow organization; 3) dust removal - as the outdoor air quality declines, it is also necessary to purify the fresh air entering the room; 4) safety - the fresh air system is dealing with the fresh air while producing no harmful by-products
