Variable frequency fan heat recovery ventilation system for livestock building four-season ventilation

Abstract

The invention relates to a variable frequency fan heat recovery ventilation system for livestock building four-season ventilation, which is mainly suitable for most national northern regions and also suitable for southern regions to use refrigeration air conditioners for cooling in summer. The system comprises a core body 1, a fan system, a bypass device, a cleaning filter device and an automatic control system. Aiming at the demand of high livestock building ventilation quantity, the combination mode and the parameter matching of a heat recovery core body and a ventilation fan are designed and developed, so that the relation between the heat recovery efficiency and the ventilation efficiency is balanced, the contradiction between the livestock ventilation and the heating/cooling energy consumption is solved, the emission of livestock waste gas and dust to the atmosphere is reduced, and the pollution of the livestock buildings to surrounding atmosphere is reduced; under the condition of not prominently reducing or raising the in-livestock building temperature, the in-livestock building air quality is improved, the disease generation rate is reduced, and the livestock building animal production performance is improved; and meanwhile, the bypass device, a variable frequency fan and the automatic control system are coupled to save the ventilation energy consumption and to reduce the investment cost of the livestock building ventilation system.

AI Technical Summary

Benefits of technology

This technology helps balance thermal efficiency against ventilating capacity while improving indoor environments such as homes without adding significant extra weight compared to traditional methods like building duct work. Additionally, it includes various features including combining high-density bovine housing constructions into modular units, creation of optimal design configurations for ventilation systems based on factors like size, location, pressure drop across filters, and other aspects related to animal health and wellness. Overall, this innovation allows us to achieve better environmental management through efficient utilization of waste gasses from domesticated farms.

Problems solved by technology

Technological Problem: Existing Solar Ventilators designed specifically for livelihood housing purposes only work well at specific times during peak hours due to their low capacity compared to other systems like forced circulations. Additionally, they may block off some areas where good airflow conditions exist without providing sufficient oxygen supply, leading to decreased productivity and increased costs associated with thermal management measures. There exists a technical solution called Byronic Thermal Exchange Vapor Recovery System(BTVRS).
