Description
Technical field
Technical field of heat exchange is the utility model is related to, more particularly to a kind of double bypass full-heat-exchange equipments.
Background technology
Full-heat-exchange equipment is widely used in technical field of heat exchange, due to heat-exchange device use in the temperature difference it is bigger
Area, so frost phenomenon often occurs, the frost phenomenon of product solution heat exchanger in the market mainly has two kinds
Mode：1st, shut down：Fresh air is closed, by air draft heat defrosting, but the stifled phenomenon of frost once occurs, air exhaust passage is blocked, melted
The meeting of frost greatly increases；2nd, preheat：Preheated in air inlet, improve the temperature for gas of entering the room, can so increase
Energy expenditure, and need to increase heater, inadequate energy-conserving and environment-protective.
Utility model content
In order to solve the problems, such as that existing heat-exchange device defrosting difficulty is big, not energy-conserving and environment-protective, the utility model provides a kind of
Full-heat-exchange equipment simple in construction, that defrosting need not be shut down.
To achieve these goals, the utility model provides one kind double bypass full-heat-exchange equipments, including body, in body
Provided with total-heat exchanger, the body side is provided with air inlet and exhaust outlet, and opposite side is provided with return air inlet and fresh wind port；Air passes through
Air inlet forms the first path to fresh wind port, and air forms alternate path through return air inlet to exhaust outlet；First path and
First switch and second switch are respectively equipped with two paths.
Further, in addition to control unit, the air inlet is provided with temperature sensor, the temperature sensor with it is described
Control unit is electrically connected.
As preferable technical scheme, the first switch and second switch are all magnetic valves.
Further, the first switch and second switch are electrically connected with described control unit respectively.
As the preferable technical scheme of the utility model, described control unit is single chip control unit.
The utility model is relative to the beneficial effect of prior art：It is double other by setting that this pair bypasses full-heat-exchange equipment
Passage, second switch is opened when the outer temperature difference is big indoors, indoor return air directly reaches air inlet, relative using interior
High temperature air reaches the purpose of defrosting, simple in construction, excellent.
Brief description of the drawings
Fig. 1 is structure principle chart of the present utility model；
Fig. 2 is the schematic diagram of use state 1 of the present utility model；
Fig. 3 is the schematic diagram of use state 2 of the present utility model.
Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
It is used to help understand the utility model for the explanation of these embodiments, but does not form to restriction of the present utility model.This
Outside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not form conflict each other
Can is mutually combined.
As shown in figure 1, a kind of double bypass full-heat-exchange equipments, including body 1, body 1 is interior to be provided with total-heat exchanger 2, this
The side of body 2 is provided with air inlet 6 and exhaust outlet 7, and opposite side is provided with return air inlet 5 and fresh wind port 8；Air arrives fresh wind port 8 through air inlet 6
The first path is formed, air forms alternate path through return air inlet 5 to exhaust outlet 7；In first path and alternate path respectively
Provided with the first magnetic valve 3 and second solenoid valve 4, two magnetic valves are used to cut-off path.
The device also includes single chip control unit (being not drawn into figure), and air inlet 6 is provided with temperature sensor, TEMP
Device and the I/O mouths of single chip control unit are electrically connected, and above-mentioned two magnetic valve is also electric with the I/O mouths of single chip control unit
Connection.Temperature sensor is used for the EAT for detecting air inlet, while temperature signal is passed into single-chip microcomputer, monolithic in real time
Machine chooses whether to be switched on or off two magnetic valves according to temperature signal.
In the present embodiment, the minimum system that single chip control unit is made up of STM89C51 single-chip microcomputers and its peripheral circuit
Form, because the control unit has been commercially highly developed technology, just also do not carry repeating in the present embodiment
For circuit diagram.
It is to close two by-passes in summer operation, fresh air obtains cold from discharge so that temperature reduces, while quilt
Fan-drying, reduce new wind moisture, when running in the winter time, fresh air obtains heat from air draft, elevates the temperature, while is arranged
Wind humidify, new wind moisture lift and utilize total-heat exchanger reclaim air draft in it is hot cold, with significant energy-saving benefit, economy
Benefit and energy-conserving and environment-protective.
As shown in Fig. 2 when spring and autumn is run, when indoor/outdoor temperature-difference is smaller (general set is less than 4 DEG C), and outdoor air
In the case of the second best in quality, total-heat exchanger and second solenoid valve 4 are closed, the first magnetic valve is opened, that is, opens first passage, room
Inner air and outer air realizes the effect of circulation, adds the ventilation of room air, had both extended the service life of total-heat exchanger,
Reduce operation cost.
As shown in figure 3, when running in the winter time, indoor/outdoor temperature-difference is big, and general temperature sensor detection outdoor temperature is less than -10
DEG C when, open second solenoid valve, now the first magnetic valve 3 is to close, that is, opens alternate path, indoor return air part warp
Over-heat-exchanger retaining heat, another part reach air inlet by alternate path, due to indoor temperature height, it is possible to reach
The effect of defrosting.
Embodiment of the present utility model is explained in detail above in association with accompanying drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, it is right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall within the scope of protection of the utility model.
