Description
Technical field
This utility model relates to air-conditioner, a kind of air-conditioner preventing condensation in winter.
Background technology
Large-size air conditioning often arranges fresh wind port, the return air that new wind can enter with return air inlet after entering air-conditioning by fresh wind port
Mixing, is then delivering to indoor by air outlet, and in the winter time, owing to the temperature of outdoor air is the lowest, and in return air, steam contains
Measuring higher, when new wind mixes with return air, new, the return air temperature mixing wind is often below the dew point temperature of mixing air state point
Degree, now mixing wind can condense on air-conditioning box inside panel, causes the internal hydrops of unitary air handling unit.Existing air-conditioner is past
Prevent condensation toward heat-preservation cotton can be added in the housing region of easily condensation, but this method can not fundamentally solve to ask
Topic.
Utility model content
The purpose of this utility model is to provide a kind of air-conditioner preventing condensation in winter, it is possible to efficiently control winter new
Wind mix with return air after the generation of condensation.
In order to solve the problems referred to above, this utility model be the technical scheme is that
A kind of air-conditioner preventing condensation in winter, including return air duct, fresh air pipeline, air supply duct, exhaust duct, return air
The sidewall of pipeline is communicated with exhaust duct, and the other end of return air duct is communicated with air supply duct, and the sidewall of air supply duct is communicated with
Fresh air pipeline, fresh air pipeline is near return air duct and air supply duct junction, and air supply duct is away from the inwall of fresh air pipeline side
Being provided with pressure fan, fresh air pipeline inwall connects heater, and heater connects temperature probe, heater and air-supply
Controller it is provided with between machine.
Fresh air pipeline inwall has horizontal socket, has support to insert in horizontal socket inside fresh air pipeline, and heater is solid
Surely it is connected on support.
Heater is air duct type electric heater.
Air duct type electric heater is low form.
The port of export of return air duct, fresh air pipeline and exhaust duct is mounted on opposite opened regulation valve.
Return air duct is provided with inspection door with exhaust duct infall and air supply duct with fresh air pipeline infall.
Controller is PLD.
Heater connects rosette, is provided with ultra-temp. control device, has ground connection ground wire and heater in rosette
Shell is connected.
By installing heater and temperature probe at fresh air pipeline inwall, can effectively monitor the temperature of new wind,
When new air temperature is less than 5 DEG C when, controller controls heater and heats new wind, then mixes with return air,
Owing to new wind is close with return air temperature through heating, it is to avoid the generation of condensation.
Accompanying drawing explanation
Fig. 1 show structural representation of the present utility model.
Detailed description of the invention
It is illustrated in figure 1 a kind of air-conditioner preventing condensation in winter, including return air duct 1, fresh air pipeline 2, air supply duct
9, exhaust duct 7, inspection door 8 and pressure fan 11, the sidewall of return air duct 1 is communicated with exhaust duct 7, the one of return air duct 1
End is communicated with air supply duct 9, and the sidewall of air supply duct 9 is communicated with fresh air pipeline 2, and fresh air pipeline 2 is near return air duct 1 and air-supply
Pipeline 9 junction, air supply duct 9 is provided with pressure fan 11 away from the inwall of fresh air pipeline 2 side, and fresh air pipeline 2 inwall has
Laterally socket, fresh air pipeline 2 is internal has support 3 to insert in horizontal socket, support 3 is fixedly connected with heater, adds hot charging
Being set to low form air duct type electric heater 4, low form air duct type electric heater 4 connects rosette 10, installs in rosette 10
Having ultra-temp. control device, this ultra-temp. control device is prior art, plays the effect of security protection when there is abnormal high temperature, will
Low form air duct type electric heater semi-finals power-off, has ground connection ground wire to be connected with low form air duct type electric heater 4 shell, low
Warm type air duct type electric heater 4 connects temperature probe 5, is provided with between low form air duct type electric heater 4 and pressure fan 11
Controlling device (not giving in figure depending on going out), control device is PLD, and this kind of PLD is prior art,
The effect of temperature probe 5 is to issue a signal to PLD, PLD control when less than set temperature value
Low form air duct type electric heater 4 processed and pressure fan 11 make corresponding action, and the present embodiment set temperature value is 5 DEG C, tool
Body temperature angle value can make corresponding change, return air duct 1, fresh air pipeline 2 and the outlet of exhaust duct 7 according to local environment change
End is separately installed with opposite opened regulation valve 6,6-1,6-2, when a large amount of return air enter return air duct 1, owing to opposite opened regulates valve 6
Regulation effect, a part of return air can through opposite opened regulation valve 6-2 be expelled directly out from exhaust duct 7, return air duct 1 and air draft
Pipeline 7 infall and air supply duct 9 are provided with inspection door 8 with fresh air pipeline 2 infall, it is simple to maintenance, arrow institute in figure
Refer to the trend for wind.
Specific works process: new wind enters from fresh air pipeline 2, by the monitoring of temperature probe 5, when new air temperature is less than 5
DEG C time, PLD controls pressure fan 11 and starts, and controls low form air channel after pressure fan 11 starts five minutes simultaneously
Formula electric heater 4 starts, and the return air that new wind enters with return air duct 1 through preheating mixes, due to new pathogenic wind-warm in air supply duct 9
Spend close with return air temperature, it is to avoid the generation of condensation, during new wind is heated by low form air duct type electric heater 4,
New air temperature can persistently raise, and when temperature is more than 60 DEG C, PLD controls low form air duct type electric heater 4 and stops
Only work, and control pressure fan 11 and quit work after five minutes, if air-conditioner needs to shut down, first close low form air duct type electricity
Heater 4, pressure fan 11 continuous running, and quit work after five minutes.
