Heat pump type fresh air ventilator set

Abstract

The invention discloses a heat pump type fresh air ventilator set. The heat pump type fresh air ventilator set comprises a fresh air ventilation pipe and a dirty air ventilation pipe, wherein the inlet end of the fresh air ventilation pipe is sequentially provided with a filter, an electrode dust removing net and an HP (High Pressure) filtering net from an inlet to an outlet; the fresh air ventilation pipe is internally provided with a fresh air blower; the dirty air ventilation pipe is provided with a dirty air exhausting blower. The heat pump type fresh air ventilator set is compact in structure, small in volume, low in pressure drop and high in efficiency. The inlet end of the fresh air ventilation pipe is sequentially provided with the filter, the electrode dust removing net, the HP filtering net, an active carbon filtering net, a nano titanium dioxide filtering net and a photocatalyst net so that the air filtering efficiency is very high. A heat pump type heat exchanger is arranged between the fresh air ventilation pipe and the dirty air ventilation pipe so that the heat recycling efficiency is high and is higher than that of a conventional fresh air ventilator by more than 40%.

Description

technical field [0001] The invention relates to a heat pump type fresh air ventilation unit. Background technique [0002] With the rapid development of the national economy, people's requirements for the environment are getting higher and higher, and the voice for improving indoor air quality is also increasing. According to statistics, among the indoor and outdoor fresh air ventilation devices, the current international popularity is the plate-fin type, The heat exchange efficiency of the rotary wheel and heat pump energy recovery devices is only 50-60%. On the basis of heat recovery, a compression refrigeration cycle is introduced, and its heat recovery efficiency is more than 40% higher than that of other fresh air ventilators. However, the fresh air and dirty air in the fresh air ventilation units in the prior art have more or less cross-contamination problems, such as the fresh air ventilation units such as the rotary wheel type and the plate-fin type, and the traditio...

Problems solved by technology

However, the fresh air and dirty air in the fresh air ventilation units in the prior art have more or less cross-contamination problems, such as the fresh air ventilation units such as the rotary wheel type and the plate-fin type, and the traditional heat pump type ventilation units also It cannot achieve cooling, dehumidification and heat recovery at the same time, and the filtration efficiency is also very low
