When new wind bypass air port 5 and air draft bypass air port 6 are opened (such as artificially or automatically), because air is through bypass air port 5, resistance when 6 is significantly less than the resistance when Total heat exchange core body 23, now be equivalent to Total heat exchange core body 23 by bypass air port 5, 6 short circuits, the new wind of indoor exhaust wind and outdoor is directly outer through air draft bypass air port 6 and new wind bypass air port 5 discharge chamber and enter indoor, thus the new blower fan of Total heat exchange type of the present invention realizes new wind and air draft all without two air channels bypass function of heat exchanging core (or being called two bypass function).Situation when this pattern is particularly suitable for the spring, autumn, indoor/outdoor temperature-difference was less.
In addition, realize two air channels bypass function by the mode arranging bypass air port in machine, the volume of new blower fan body can not be increased.
Certainly, it is contemplated that new blower fan of the present invention also only can cut out one of them bypass air port, thus single bypass function is realized.
For improving the ease of use of new blower fan, the present invention preferably arranges new wind bypass air-valve 11 at new wind bypass air port 5 place, and in air draft bypass air port 6, place arranges air draft bypass air-valve 13, to control the break-make of new wind, air draft bypass gas circuit.That is, when new wind bypass air-valve 11 is opened, new wind enters new wind bypass gas circuit by new wind air inlet 1, enters indoor by new wind air outlet 4; When air draft bypass air-valve 13 is opened, air draft enters air draft bypass gas circuit by air draft air inlet 2, by outside air draft air outlet 3 discharge chamber.

Preferably, be improve the convenience that user uses, the new blower fan of Total heat exchange type of the present invention can know indoor air temperature and outside air temperature automatically, thus is convenient to user and selects suitable operational mode, such as Total heat exchange pattern or two air channels bypass mode.For this reason, the new blower fan of described Total heat exchange type also comprises the outside air temperature checkout gear (such as temperature sensor) 15 that can carry out temperature detection to the air that side enters new wind air inlet 1 outdoor and the indoor air temperature checkout gear (such as temperature sensor) 16 that can detect the air themperature that side enters air draft air inlet 2 indoor.Outside air temperature checkout gear 15 is preferably arranged in new wind air inlet, and indoor temperature detection device 16 is preferably arranged in air draft air inlet 2, thus can in new fan operation process the temperature of new wind and indoor exhaust wind outside real-time sensing chamber.
Preferably, the new blower fan of Total heat exchange type of the present invention also comprises control device, described control device can control the opening and closing in described new wind bypass air port 5 and air draft bypass air port 6 according to the difference of the indoor air temperature detected and outside air temperature, especially control the opening and closing of described new wind bypass air-valve 11 and air draft bypass air-valve 13.
Such as, when outside air temperature checkout gear 15 and indoor air temperature checkout gear 16 detect that the difference of outside air temperature and indoor air temperature is larger, such as, when being not less than certain setting value Δ φ (such as the value of less than 5 DEG C), control device is thought should perform Total heat exchange operational mode, then new wind bypass air-valve 11 is in closure state (as shown in Figure 4) with air draft bypass air-valve 13.In this opportunity, air-flow is as shown in the arrow curve in Fig. 3 A, the new wind in outside enters new wind air intake air chamber 7 by outdoor new wind air inlet 1, and enters indoor through Total heat exchange core body 23, new wind air-supply air chamber 9, new wind pressure fan 17 and new wind air outlet 4 (they form new wind path jointly); Indoor air draft enters air draft air intake air chamber 8 by indoor exhaust wind air inlet 2, and outside Total heat exchange core body 23, air draft air-supply air chamber 10, air draft pressure fan 18 and indoor exhaust wind air outlet 3 (they form air draft path jointly) discharge chamber.Flow in outdoor new wind and the indoor exhaust wind different runners in Total heat exchange core body, owing to there is temperature and psychrometric difference in outdoor new wind and indoor exhaust wind, so complete the exchange of temperature and humidity in Total heat exchange core body, thus reduce heat or loss of refrigeration capacity to greatest extent, economize energy.
The difference of the indoor air temperature detected when the new air temperature in the outside that outside air temperature checkout gear 15 detects and indoor air temperature checkout gear 16 is less, time such as lower than certain setting value Δ φ, control device is thought and is suitable for performing two bypass operation, then control respectively to open new wind bypass air-valve 11 and air draft bypass air-valve 13, such as, new wind bypass air-valve 11 and air draft bypass air-valve 13 is opened respectively, as shown in Figure 6 by controlling drive motors 12 and 14.In this opportunity, air-flow is as shown in the arrow curve in Fig. 5 A, and outdoor new wind and indoor exhaust wind two strands of air-flows enter indoor with outside discharge chamber respectively by new wind bypass gas circuit and air draft bypass gas circuit.That is, indoor exhaust wind is made to enter air draft air-supply air chamber 10 by air draft air intake air chamber 8 by air draft bypass air port 6, and by air draft pressure fan 18 by outside air draft air outlet 3 discharge chamber; Outdoor new wind enters new wind air-supply air chamber 9 by new wind air intake air chamber 7 by new wind bypass air port 5, and sends into indoor by new wind pressure fan 17 by new wind air outlet 4.After each air-valve is opened, the new blower fan of Total heat exchange type of the present invention is in two bypass function pattern, because two strands of air-flows are not all by Total heat exchange core body 23, so correspondingly reduce machine internal resistance.
Preferably, the setting value of new air temperature and indoor air temperature difference can be set by producer, and preferably also can by user's sets itself, such as can carry out sets itself by user within the specific limits according to actual service condition or adopt MANUAL CONTROL mode (such as user directly can input setting value or carry out increase and decrease adjustment to setting value) as required.The function of user's sets itself is such as provided by control device.
Such as, the gas flow temperature of serviceability temperature checkout gear to new wind and air draft detects, can by user according to the unlatching situation design temperature of indoor temperature regulating device difference Δ φ as threshold value, and aweather control valve device sends signal, and the saving realizing the energy uses.According in actual service condition, the setting value of air-valve control device is changed simultaneously, during as design temperature is revised as 8 DEG C from 5 DEG C, can opening time of corresponding increase bypass system and temperature range, the difference needs of different user indoor temperature can be realized, thus improve the comfort level of user.
Preferably, the new blower fan of Total heat exchange type of the present invention also comprises the first device for detecting static pressure 21 and the second device for detecting static pressure 22 being respectively used to the static pressure detecting new general mood road (comprising new wind path and new wind bypass gas circuit) and air draft gas circuit (comprising air draft path and air draft bypass gas circuit), as shown in Figure 1B, 3B and 5B.Particularly, first device for detecting static pressure 21 such as can be arranged in new wind air-supply air chamber 9, second device for detecting static pressure 22 such as can be arranged in air draft air-supply air chamber 10, thus no matter is the static pressure that all can detect under Total heat exchange pattern or under two bypass mode in new general mood road and air draft gas circuit.
Device for detecting static pressure is set in machine to detect the pressure differential on new general mood road and air draft gas circuit, and then correspondingly can control the rotating speed of new wind pressure fan and/or air draft pressure fan, be convenient to the equilibrium ensureing new wind air output and air draft air output, thus can avoid occurring that air draft air output causes the situation of indoor negative pressure higher than new wind air output.Because once negative pressure appears in indoor, outdoor air just can enter indoor by any approach (such as door and window gap etc.) without filtration, causes IAQ to decline.
Preferably, because the new blower fan of Total heat exchange type of the present invention has two air channels bypass mode, thus the aperture in described new wind bypass air port and/or described air draft bypass air port can be controlled according to the pressure differential of the new general mood road detected and air draft gas circuit, in particular, control device for controlling air-valve drive motors can be set, to regulate the rotational angle of corresponding bypass drive motors according to described pressure differential, thus control bypass air-valve 11,13 opening angle.
Such as, when indoor and outdoor temperature difference is lower than setting value, bypass air-valve 11, 13 open rear newly general mood roadlock power and air draft gas circuit resistance can correspondingly change, if air draft air output is higher than new wind air output, then indoor present negative pressure, there will be outdoor air directly by the suction chamber of position, gap, room, new wind intake and air draft air output is regulated (such as with the opening angle size of air draft bypass air-valve 13 in the case by controlling new wind bypass air-valve 11, increase the opening angle of new wind bypass air-valve and/or reduce the opening angle of air draft bypass air-valve), just the difference of new wind air output and air draft air output can be made to maintain in suitable scope, realize indoor and be again in malleation.This adjustment mode, compared to the rotating speed adjusting new wind pressure fan and/or air draft pressure fan, implements more simple effective.
Preferably, the new blower fan of Total heat exchange type of the present invention also comprises the fan rotation speed detecting device 20 detecting air draft pressure fan rotating speed, and controls the rotation speed of fan control device 19 of the rotating speed of air draft pressure fan 18 according to the signal of described fan rotation speed detecting device 20.Detected by fan rotation speed detecting device 20 pairs of rotation speed of fan, and controlled (such as reducing rotating speed) by the rotating speed of rotation speed of fan control device 19 pairs of direct current generators, the constant control of air quantity can be realized.
So, no matter the new blower fan of Total heat exchange type runs under Total heat exchange pattern or runs under two bypass mode, be greater than the situation of new wind air output if there is air draft air output, just can control by rotation speed of fan the rotating speed that 19 reduce air draft pressure fan 18, to realize the equilibrium of air quantity.Obviously, when adopt control the mode of rotation speed of fan realize air quantity balanced time, the rotating speed that the rotating ratio reducing air draft pressure fan improves new wind pressure fan is safer feasible.
Certainly, it is envisioned that fan rotation speed detecting device 20 also can be arranged to the rotating speed detecting new wind pressure fan 17, rotation speed of fan control device 19 correspondingly controls the rotating speed of the drive motors of new wind pressure fan 17.
The present invention changes new wind by design machine inner structure and realizes not increasing body volume from the air flow direction of air draft and new wind and air draft are carried out the object of bypass by different air flue simultaneously, eliminates in prior art and only the new wind side of causing during an air draft air-flow list bypass and air draft side is occurred that pressure reduction causes outdoor gas directly by the situation in the suction chamber of space, room.Meanwhile, adopt two bypass design to improve bypass scavenging efficiency, improve the environment for use scope of full-heat-exchange equipment.
To sum up, the principal character of the new blower fan of Total heat exchange type of the present invention adopts two air channels by-pass collar, do not increase cabinet size simultaneously.When using bypass function, outdoor new wind and indoor exhaust wind are all entered outside indoor or discharge chamber by respective bypass passageways, realize the spring, season in autumn two temperature difference less do not need use hot-swap feature situation under carry out the exchange of new wind and air draft.Preferred version of the present invention also achieves and prevents indoor from occurring negative pressure state, avoids unfiltered outdoor air from the suction chamber of space, room, and improves the scavenging efficiency of bypass function, reduce energy ezpenditure, reduce the loss of heat exchanging core.
The present invention comprises compared to the main improvement of prior art:
