Abstract

The invention discloses a heat exchanger energy recovery device, and belongs to the technical field of ventilation energy-saving equipment. The problem that an existing energy recovery device is low energy recovery rate is solved. The heat exchanger energy recovery device comprises a fresh air channel module, a fresh air section filter module, a fresh air section heat exchange module, a fresh airsection electric heater and a fresh air section power module, wherein the fresh air section filter module, the fresh air section heat exchange module, the fresh air section electric heater and the fresh air section power module are sequentially arranged in the fresh air channel module in sequence according to an intake path. The heat exchanger energy recovery device further comprises an exhaust channel module, an exhaust section filter module, an exhaust section heat exchange module and an exhaust section power module, wherein the exhaust section filter module, the exhaust section heat exchange module and the exhaust section power module are arranged in the exhaust channel module in sequence according to an exhaust path. The fresh air section heat exchange module and the exhaust section heat exchange module each comprises at least two heat exchangers, each heat exchanger in the exhaust channel module is connected with all the heat exchangers in the fresh air channel module through heatexchange pipes, and the exchange of heat exchange mediums is achieved through power pumps and valves. The heat exchanger energy recovery device is a ventilation energy recovery system, recovers heatof exhaust air for heating a fresh air system, serves as a fresh air heating source, and prevents ineffective waste of energy.

Description

Technical field [0001] The invention relates to an energy recovery device, in particular to an energy recovery device for a heat exchanger, and belongs to the technical field of ventilation and energy-saving equipment. Background technique [0002] At present, the exhaust of most ventilation systems in cold and severe cold areas is to directly exhaust high-temperature indoor air to the outdoors, resulting in huge energy waste; at the same time, heating the outdoor low-temperature fresh air to indoor temperature not only requires a lot of energy, but also In severe cold and cold areas, because the outdoor temperature is too low and the cold area is too low, the heating and hot water heating heat exchanger is easy to freeze. Therefore, the fresh air heat source problem in severe cold and cold areas not only has the problem of high energy consumption, but also has the heat source for fresh air heating Difficult problems. [0003] There are two commonly used forms of the most widely u...
