Purified fresh air ventilating device with temperature and humidity adjusting function

Abstract

The invention relates to a purified fresh air ventilating device with a temperature and humidity adjusting function. An outdoor unit is connected to a super cooling heater in an indoor unit through arefrigerant tube; a wet film humidifier is arranged on the left side of the surface cooling heater and communicates to a humidifying water pipe; an ultra-low resistance high and medium effect filter and an ultraviolet sterilizing screen are successively arranged on the left side of the wet film humidifier; the ultraviolet sterilizing screen is arranged on the inner side of an air supply outlet; afresh air inlet is formed in the upper right side of the indoor unit, and an auxiliary electric heating device, a primary filter and an air blower are successively arranged on the left side of the fresh air inlet; a heat recovery core body is arranged on the positive pressure side of the air blower; fresh air exchanges heat with exhausted air in the heat recovery core body through the primary filter and the air blower for pre-cooling treatment and passes the surface cooling heater; when the outdoor temperature is higher than 5 DEG C, the fresh air exchanges heat with exhausted air in the heatrecovery core body for pre-cooling treatment; when the outdoor temperature is lower than 5 DEG C, the auxiliary electric heating device preheats the fresh air to 5 DEG C and exchanges heat with the exhausted air in the heat recovery core body; and temperature and humidity entering indoors can be adjusted.

Description

technical field [0001] The invention belongs to the technical field of ventilating devices, and in particular relates to a purifying fresh air ventilating device with the function of regulating temperature and humidity. Background technique [0002] At present, the common fresh air ventilators in the world include plate-fin type, rotary wheel type, heat pump type, etc., and their heat exchange efficiency is only 50-70%. The above-mentioned type of fresh air ventilator exchanges heat between indoor and outdoor air through a heat exchanger installed inside it, and then discharges the heat-exchanged indoor air to the outside, and at the same time, the outdoor air enters the room after heat exchange. Since this type of fresh air ventilator only exchanges heat through a heat exchanger, it cannot accurately control the temperature and humidity of the air entering the room. When the outdoor temperature is too high or too low, the temperature and humidity of the air passing through...

Problems solved by technology

Since this type of fresh air ventilator only exchanges heat through a heat exchanger, it cannot accurately control the temperature and humidity of the air entering the room

When the outdoor temperature is too high or too low, the temperature and humidity of the air passing through the ventilator cannot meet people's demand for air quality
