Swing core purification and energy-saving ventilator

Abstract

The invention is a pendulum-type purifying energy-saving ventilator, which belongs to an energy-saving ventilating and air purifying device, and is used for indoor and outdoor ventilation, recovery of exhaust energy and purification of fresh air. The purpose of the present invention is to solve the defects of the existing fresh air ventilators such as low efficiency, complex structure, high failure rate, easy to be blocked holes, and no purification function for fresh air. The present invention includes a casing, a fan and a heat exchanger, and its characteristics The frame-type heat exchange core made of fiber material is placed in the heat exchange chamber for intermittent swing to realize the airflow switching of the air duct in the machine, so that the fresh air and exhaust air alternately pass through the heat exchange material from the opposite direction for heat exchange , it not only has the advantages of high heat storage heat exchange efficiency, but also has the unique characteristics of fiber heat exchangers to filter and purify air, and eliminates the possibility of failures caused by large rotating parts and complex gas distribution mechanisms. In order to finally solve various technical problems faced by the popularization and application of existing technologies, and make new contributions to the cause of energy conservation and environmental protection.

Description

[0001] Technical field: [0002] The invention relates to an energy-saving indoor air purification device, in particular to a purifying energy-saving ventilator for indoor and outdoor ventilation, recovery of exhaust energy and purification of fresh air. [0003] Background technique: [0004] Energy crisis and environmental pollution are the two biggest threats facing all mankind. Indoor ventilation is the most important measure to eliminate indoor air pollution, and recycling air-conditioning energy taken away by ventilation is the only means to ensure economical ventilation. . Energy recovery ventilators have been around since the 1970s. It is commonly known as fresh air ventilator in the industry. For more than 40 years, this product has attracted widespread attention. Its key technology is the heat exchanger. In order to obtain higher heat recovery rate and lower cost, several different technical solutions have appeared in the world.

AI Technical Summary

Problems solved by technology

Although it is currently the best technical solution in terms of cost and economy, its structure is still complicated and its failure rate is relatively high because of the addition of an air distribution mechanism that continuously switches air. In addition, one of its two channels Working under positive pressure, the heat exchange material is placed at the air outlet of the centrifugal fan, and the high-speed airflow directly blows the heat exchange material, resulting in a large loss of pressure and kinetic energy, and it is difficult to balance the air volume of the two channels, and the fresh air outlet and the exhaust air outlet are different. Only half of the channels are opened alternately, and the wind resistance is relatively large, so the air volume and heat transfer efficiency of this solution are also limited to a certain extent.
