In sum, the present invention new wind heat pump achieves as the outdoor filtered fresh air of indoor offer, and indoor muddiness air is discharged to outdoor.Outdoor fresh air passes through filter net type air filter or electrostatic adsorption type air filter, crosses fine particle in air filtering, filters its effect of 0.5-1um and reaches more than 95%；Fresh air carries out heat exchange by sensible heat exchanger and indoor exhaust wind, carries out energy regenerating, reaches energy-saving effect；Fresh air continues through Fresh air handing heat exchanger (finned heat exchanger), fresh air is freezed, dehumidifies or heat treated, and the fresh air making feeding indoor is more comfortable；The waste gas simultaneously got rid of carries out the second weight energy recovery process on outside energy recovering heat exchanger (finned heat exchanger)；Fresh air continues through auxiliary electric heater unit, when outdoor temperature is too low, can be controlled auxiliary electric heater unit by microcomputer control system further and open, improve the temperature of the fresh air sending into indoor；Fresh air continues through anion generator, and produced anion is sent into indoor, to reach more healthy room air standard, kills the harmful substances such as the antibacterial of indoor, mycete and acarid simultaneously.Send, exhaust fan uses can stepless speed regulation DC or EC blower fan, microcomputer control system compares calculating according to all kinds of parameters detected with arranging parameter, controlling DC or EC rotation speed of fan, reach fresh air more comfortable, dual energy-recuperation system can reach more energy-conservation effect.In air conditioner heat pump system, compressor can use constant speed compressor, frequency-changeable compressor and digital scroll compressor.The air themperature that arranges on microcomputer control system according to user, humidity parameter, microcomputer control system controls air conditioner heat pump system and carries out freezing, dehumidifying or heat treated.
In a word, the new wind heat pump of the present invention has major technological breakthrough compared with tradition fresh air ventilator, has the advantage that
One, it is transported to the temperature scalable of the fresh air of indoor, makes to be transported to the effect that indoor fresh air is more comfortable, more energy-conservation.
Two, it is transported to the humidity scalable of the fresh air of indoor, makes to be transported to the effect that indoor fresh air is more comfortable, more energy-conservation.
Three, ventilation problem when the outdoor gas concentration lwevel of solution is bigger than indoor concentration, it is to avoid room air is by outdoor air pollution.
Four, multiple man-machine conversation mode is used, it is simple to user controls this new wind heat pump.
Five, outdoor fresh air passes through filter net type air filter or electrostatic adsorption type air filter, crosses fine particle in air filtering, filters its effect of 0.5-1um and reaches more than 95%, and making the fresh air being transported to indoor is pure air.
Six, have employed the double energy recovery system of air heat exchanger and air conditioner heat pump system so that the energy consumption of balanced type air exchange system is greatly lowered.
Additionally, the differentiation equipment of different purposes can be derived further according to the new wind heat pump of the present invention, the brand-new intelligent air-conditioning system shown in dehumidifier as shown in figure 12 and Figure 13.
In dehumidifier shown in Figure 12, relative to the new wind heat pump of the present invention, air heat exchanger omits, fresh air channel wind feeding section cuts off with wind outlet section, fresh air channel wind feeding section connects with the wind outlet section of return air channel, return air channel wind feeding section cuts off with wind outlet section, and return air channel wind feeding section connects with the wind outlet section of fresh air channel.
In Figure 13, in fresh air channel wind feeding section, in return air channel wind feeding section, in fresh air channel wind feeding section and the spaced walls of the wind outlet section of return air channel and the spaced walls of fresh air channel wind outlet section and the wind feeding section of return air channel be respectively provided with air-valve 61, according to user demand, air-valve can be carried out different closing control, reach different instructions for uses, can integrated fresh air purifying, temperature, humidity regulation brand-new intelligent air-conditioning system, the air conditioner group of user's constant temperature, constant humidity, permanent oxygen is provided, overturn tradition VRV system, more comfortable, more healthy, more energy efficient.Specifically, when two air-valves of horizontal direction (i.e. the direction of parallel wall box) cut out, two air-valves of vertical direction are opened, it is simply that fresh air conditioner heat pump；When the air-valve of horizontal direction is opened, two air-valves of vertical direction cut out, it is simply that variable refrigerant volume air conditioning system.Principle is made with aforementioned during fresh air conditioner heat pump；The microcomputerized control of new wind heat pump can according to indoor temperature, humidity, gas concentration lwevel change, controlling the frequency of frequency conversion exhaust blower and the new blower fan of frequency conversion, thus controlling air quantity, and controlling the ability of digital scroll compressor.So indoor meeting is more comfortable, more energy-conservation.When running as variable refrigerant volume air conditioning system, microcomputerized control according to indoor temperature, humidity, can control the frequency of frequency conversion exhaust blower and the new blower fan of frequency conversion, thus controlling air quantity, with control digital scroll compressor frequency, thus controlling the ability of digital scroll compressor.When indoor carbon dioxide concentration increases, microcomputerized control can adjust valve area and the opening time of two vertical direction according to indoor carbon dioxide concentration, introduces outdoor new wind.
Without departing from the thought of the invention, the various different embodiments of the present invention are carried out combination in any, all should be considered as present disclosure；In the technology concept of the present invention, technical scheme is carried out multiple simple modification and the combination in any of the thought without prejudice to the invention that different embodiment carries out, all should within protection scope of the present invention.
