Novel photovoltaic thermoelectricity heat recovery and purification fresh air device and control method thereof

Abstract

The invention discloses a novel photovoltaic thermoelectricity heat recovery and purification fresh air device and a control method thereof, and belongs to the technical field of heating ventilation air conditioning and green building energy saving. The fresh air device comprises a heat pipe heat recovery module, a fresh air purification module, a photovoltaic thermoelectricity module and an automatic control module, wherein one end of the heat pipe heat recovery module is arranged in a fresh air channel, and the other end of the heat pipe heat recovery module is arranged in an exhaust channel. The air purification module comprises an initial filtering layer, an efficient filtering layer and an adsorption layer. The photovoltaic thermoelectricity module comprises a photovoltaic cell panel,a storage battery, a controller and a thermopile, wherein the photovoltaic cell panel is laid on the upper surface of an outdoor side air pipe, and heat pipes of a fresh air pipe and an exhaust pipeare connected through the thermopile to intensify heat exchange. The automatic control module comprises a temperature sensor and a control module. By means of the novel fresh air device and the control method thereof, the problem that the energy of exhaust air is wasted is solved; moreover, solar energy is adopted for assisting in intensifying heat exchange, the heat recovery efficiency on the exhaust air is greatly improved, energy consumption of an air conditioning system is sufficiently reduced, and therefore, the fresh air device has a substantial application prospect.

Description

technical field [0001] The invention relates to HVAC and green building energy-saving technologies, in particular to a novel photovoltaic thermoelectric heat recovery and purification fresh air device and a control method thereof. Background technique [0002] Energy shortage and environmental pollution are two major problems faced by human beings for a long time. The data shows that in my country's total energy consumption, the proportion of total building energy consumption is gradually increasing, and among the building energy consumption is mainly air conditioning energy consumption, accounting for 50% to 60% or even more of building energy consumption. In the energy consumed by the air conditioning system, fresh air load accounts for about 30%. Changes in the state of fresh air have a great impact on the load and energy consumption of the air conditioning system, and the indoor air that has been cooled or heated is directly discharged outdoors. Great waste of energy. ...
