Description

Purifying fresh air air interchanger with temperature and humidity adjustment function
Technical field
The invention belongs to air interchanger technical fields, and in particular to the purifying fresh air with temperature and humidity adjustment function, which is taken a breath, to be filled It sets.
Background technique
International common fresh air ventilator has the forms such as plate-fin, rotary-type, heat-pump-type at present, and heat exchanger effectiveness only has 50~70%.The above-mentioned type fresh air ventilator with outdoor air indoor by its internal heat exchanger being arranged by carrying out Then indoor air after heat exchange is discharged to outdoor by heat exchange, while outdoor gas enters the room after heat exchange.Due to this Type fresh air ventilator is only exchanged heat by heat exchanger, and the temperature and humidity of the air entered the room can not be accurately controlled.Work as outdoor When temperature is excessively high or too low, demand of the people to air quality is unable to satisfy by the temperature and humidity of the air of ventilator.
Summary of the invention
To overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide the purification with temperature and humidity adjustment function is new Wind air interchanger has the characteristics that the temperature and humidity of the controllable air entered the room.
To achieve the above object, the technical solution adopted by the present invention is that:Purifying fresh air with temperature and humidity adjustment function changes Device of air, includes outdoor unit, and outdoor unit is connected by refrigerant pipe with the cold heater of the table in indoor unit;A left side for the cold heater of table Side is equipped with wet-membrane humidifier, and wet-membrane humidifier is connected with humidification water pipe;Low-resistance height is successively arranged on the left of wet-membrane humidifier Medium effeciency filter, ultraviolet sterilization net;Ultraviolet sterilization net is located on the inside of air outlet;The upper right side of indoor unit enters equipped with fresh air Mouthful, the left side of fresh air inlet is successively arranged auxiliary electric heater unit, primary filter, pressure fan to the left;Heat recovery core is located at The positive pressure side of pressure fan;Exhaust blower is located on the inside of wind exhausting outlet.
The heat recovery core upper left side is equipped with exhaust outlet, and exhaust outlet is for being discharged indoor gas.
The beneficial effects of the invention are as follows:
Compared with prior art, the present invention is for deficiency existing for existing ventilator, the cold heating of integrated meter in ventilator Device, auxiliary electric heater unit, wet-membrane humidifier and air cleaning unit can satisfy aerial temperature and humidity throughout the year and cleanliness Demand.
Due to being equipped with ultraviolet sterilization net 10, so having the characteristics that sterilize outdoor fresh air;Due to being equipped with the cold heating of table Device 7 and outdoor unit 13, so having the characteristics that accurately to adjust the temperature for entering the room air;Due to being equipped with auxiliary electric heater unit 4, so having the characteristics that antifreeze when winter outside air temperature is lower;Due to being equipped with wet-membrane humidifier 8, so having phase outside winter room The characteristics of entering the room the relative humidity of air, is adjusted when lower to humidity;Due to being equipped with low-resistance high-medium efficient filter, so Have the characteristics that filter outdoor air pollutant.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure:1- indoor unit;2- heat recovery core;3- pressure fan;4- auxiliary electric heater unit;5- primary filter;6- Exhaust blower;The cold heater of 7- table;8- wet-membrane humidifier;9- low-resistance high-medium efficient filter;10- ultraviolet sterilization net;11- humidification Water pipe;12- refrigerant pipe;13- outdoor unit.
Specific embodiment
Structural principle and working principle of the invention are described in further detail with reference to the accompanying drawings and examples.
Referring to Fig. 1, the purifying fresh air air interchanger with temperature and humidity adjustment function, includes outdoor unit 13, outdoor unit 13 It is connected by refrigerant pipe 12 with the cold heater 7 of the table in indoor unit 1;The left side of the cold heater 7 of table is equipped with wet-membrane humidifier 8, wet Film humidifier 8 is connected with humidification water pipe 11;The left side of wet-membrane humidifier 8 is successively arranged low-resistance high-medium efficient filter 9, ultraviolet Line bactericidal net 10;Ultraviolet sterilization net 10 is located on the inside of air outlet;The upper right side of indoor unit 1 is equipped with fresh air inlet, fresh air inlet Left side be successively arranged auxiliary electric heater unit 4, primary filter 5, pressure fan 3 to the left;Heat recovery core 2 is located at pressure fan 3 Positive pressure side;Exhaust blower 6 is located on the inside of wind exhausting outlet.
2 upper left side of heat recovery core is equipped with exhaust outlet, and exhaust outlet is for being discharged indoor gas.
The working principle of the invention is:Summer:Fresh air passes through primary filter 5 and pressure fan 3 by fresh air inlet, with row Wind heat exchange in heat recovery core 2 carries out precooling treatment, then passes through the cold heater 7 of table, passes through 13 compression mechanism of outdoor unit Further cooled down after SAPMAC method, after reaching set temperature, by low-resistance high-medium efficient filter 9, ultraviolet sterilization net 10, It is sent into indoor.
Winter:When outdoor temperature is higher than 5 DEG C, fresh air passes through primary filter 5 and pressure fan 3 by fresh air inlet first, The pre-heat treatment is carried out in 2 heat exchange of heat recovery core with air draft, then passes through the cold heater 7 of table, passes through 13 compressor of outdoor unit Fresh air is heated to set temperature after heating circulation, by low-resistance high-medium efficient filter 9, ultraviolet sterilization net 10, is sent into room It is interior.
When outdoor temperature is lower than 5 DEG C, when 13 operational efficiency of outdoor unit is low or can not start, unlatching is set to fresh air and enters Then auxiliary electric heater unit 4 at mouthful carries out level-one in 2 heat exchange of heat recovery core with air draft and adds by fresh air preheating to 5 DEG C Heat heat treatment, using the cold heater 7 of table, by the way that fresh air is heated to set temperature after 13 compression mechanism thermal cycle of outdoor unit, By low-resistance high-medium efficient filter 9, ultraviolet sterilization net 10, it is sent into indoor.
