1. Introduction to the Project

1.1 Introduction to technical achievements

The Qianjia ventilation constant pressure machine has four major functions: balancing indoor and outdoor negative pressure, purifying indoor air, providing a complete gas leakage alarm solution, and ventilation and heating functions. It is used to solve the problems of negative pressure and air purification caused by the operation of exhaust or range hood indoors.

1.2 Technical analysis and advantages

1.2.1 Core technical analysis

The ventilation constant pressure machine adopts the main intelligent circuit control. When the indoor and outdoor pressure difference exceeds 20Pa (a standard atmospheric pressure of about 700P), the equipment automatically opens for pressure compensation. The intelligent temperature control system automatically heats the outdoor cold air, and the indoor and outdoor temperature difference does not exceed 10℃. There are also two filters to prevent mosquitoes and dust from entering the room. The filter cotton inside is cleaned once a year and easy to disassemble. The heating function can be used as electric hot air. The machine is also equipped with a gas leak alarm device inside, which automatically alarms and ventilates when there is a gas leak to avoid the unnecessary loss of life and property.

1.2.2 Technological innovation and advantages

The Qianjia ventilation constant pressure machine is a patented product with independent intellectual property rights of Chunweicheng Machinery Equipment Co., Ltd., with the Patent No. 202011215654.8. It is equipped with 13 imported industrial chips, 304 stainless steel main board, fully intelligent automatic adjustment of indoor pressure, ceramic vector heating to balance indoor and outdoor temperature differences, convenient installation, and large customization space.

1.3 Main products and applications of technical achievements

The Qianjia brand ventilation constant pressure machine is applied in household life, office spaces, hospital wards, and underground enclosed spaces, catering to the consumers who care about health, environmental protection, and comfortable living. According to different data reports and analyses, the consumer audience of the product is mainly the middle and high-end income group, who are more concerned about indoor air quality, prevention of bacteria and viruses, and other issues. In addition, people with respiratory diseases or allergic symptoms may also become potential consumers.

1.4 Stage of technological achievements

The project product has completed industrialization.

By now, more than 20 patents have been obtained.

2. Market Potential Analysis

In recent years, with the continuous emergence of air pollution and indoor decoration pollution, consumers have become more concerned about household health, and indoor ventilation is particularly important. Medical data shows that a person needs 20-30 cubic meters of fresh air per hour to feel comfortable. Poor ventilation will inevitably lead to insufficient oxygen content and an increase in turbid air such as carbon dioxide in the living room. People living in this environment will soon experience sub-health symptoms such as dizziness, bloating, chest tightness, and fatigue.

Nowadays, most of the residential buildings of urban residents are made of reinforced concrete and aluminum alloy doors and windows, which are tightly decorated and lack ventilation. Especially for high-rise buildings in downtown areas, doors and windows are closed all year round, which inevitably leads to poor indoor ventilation. Due to the lack of consideration for the air intake function during building construction, the current buildings are centralized for water supply and drainage, with centralized smoke exhaust in the flue. The exhaust of each household’s range hood and bathroom is now standard, and its power is increasing. As the sealing of doors and windows gradually improves, the indoor and outdoor isolation also improves. Therefore, when the doors and windows are closed (especially in the spring, autumn, winter seasons in the north and summer in the south), negative pressure is immediately generated when the range hood starts. Due to the principle of strong atmospheric pressure, the indoor and outdoor air pressure needs to be balanced, and the airtightness of doors and windows is good. When it is difficult for gas to enter through the gaps or only in small amounts, continuous negative pressure can only be supplied from the sewer. Due to the fact that all building drainage pipes are connected and also connected to outdoor drainage wells, a large amount of gas enters the room through the only high flow channel of the drainage pipes to supplement negative pressure. Not only does it have an unpleasant odor, but it also spreads bacteria and viruses.

Ventilation, also known as air exchange, is the process of using mechanical or natural methods to deliver sufficient fresh air into indoor spaces, while also expelling polluted air that does not meet hygiene requirements so that the indoor air meets hygiene requirements and production process requirements. Ventilation constant pressure machine is a commonly used ventilation equipment in air conditioning engineering. The Qianjia ventilation constant pressure machines are mainly used in residential and office buildings, mainly to solve the problem of air pressure balance in enclosed spaces. All living rooms that use well sealed plastic steel windows, broken bridge aluminum, wood clad aluminum, and glass doors and windows are within the scope of use. After going public, its market share will exceed that of the air conditioning market, filling in the gap in domestic and foreign markets. Currently, there are no similar products in the market, and the international space is also very broad.

3. Financing Needs and Purposes
