AI Technical Summary

Technical Problem

Existing heat recovery fresh air systems lack intelligent judgment of outdoor fresh air humidity, causing rotary dehumidifiers to operate under unnecessary conditions, increasing energy consumption and carbon emissions. Furthermore, the regenerated heat source relies on electricity or gas, resulting in high energy consumption.

Method used

The system uses a primary humidity sensor to obtain outdoor fresh air humidity information, dynamically selects the fresh air path, and combines the air conditioning waste heat recovery pipeline to preheat the regenerated air, thereby reducing the heat source consumption of the rotary dehumidifier.

Benefits of technology

By intelligently determining the humidity of fresh air, unnecessary operation of rotary dehumidifiers is reduced, thereby lowering system energy consumption and carbon emissions, and optimizing the utilization of the regenerative heat source of the rotary dehumidifier.

Abstract

The utility model provides a zero carbon building heat recovery fresh air system, including fresh air pipeline, fresh air bypass pipeline, exhaust pipeline, first humidity sensor, first heat exchanger, regenerative wind pipeline, rotary dehumidifier, second heat exchanger and air conditioning waste heat recovery pipeline, and fresh air pipeline and exhaust pipeline all communicate indoor, outside, and carry out heat exchange in first heat exchanger, first humidity sensor is located in fresh air pipeline close to one end of outdoor, and fresh air bypass pipeline is located in first heat exchanger close to one end of outdoor connection with fresh air pipeline, and one side passway of rotary dehumidifier is into fresh air bypass pipeline, and the other side passway of rotary dehumidifier is into regenerative wind pipeline, and the cold side of second heat exchanger is into regenerative wind pipeline, and the hot side of second heat exchanger is into air conditioning waste heat recovery pipeline. The utility model has solved the technical problem of unnecessary operation energy consumption and carbon emission in prior art system and the technical problem of high energy consumption because the rotary dehumidifier regenerative heat source only relies on electric energy or gas.
