Description
Technical field
The utility model is related to the design of air conditioner for elevator and manufacturing technology fields, are a kind of car overhead air conditioner for elevator systems
System.
Background technology
With the improvement of people's house, elevator is used more and more, moreover, requirement of the people to elevator is also increasingly
It is high.It does not require nothing more than fast, steady, mute, and requires beautiful, comfortable, include the requirement to air-conditioning.Therefore, with air-conditioned elevator
Gradually there is market.Elevator air-conditioning generally can be divided into car overhead airconditioning system and external according to the difference for sending wind environment back to
Unit（Hoistway）Air supply air-conditioner system.The car overhead airconditioning system refers to that elevator is directly put or be suspended on to air-conditioner host
On the crossbeam of car top, air conditioner releases the air in car, through refrigeration（Heat）Send back in car again afterwards, so week and
It renews, reaches the air-conditioning system for adjusting temperature purpose in car.The external unit（Hoistway）Air supply air-conditioner system refers in electricity
Air-conditioner set is set outside stair shaft road or by building central air conditioner system, the air handled well is sent into elevator by ajutage
In hoistway, then by the wind turbine feeding car of car top, the system for realizing air temperature modification in car.
In comparison, the external unit（Hoistway）The deficiency of air supply air-conditioner system is：It needs to increase pipeline air port
Quantity, investment is big, and energy expenditure is big, and the improper fluctuation of wind pressure of central air conditioner system is easily caused under the high-speed cruising of elevator.
And car overhead airconditioning system, because it can use for reference the air-conditioning technical of existing mature and reliable, and investment is small, and refrigeration is rapid, energy
Consumption is also little, so be widely adopted.Therefore, the elevator air conditioning system that most of construction projects use currently on the market is sedan-chair
Compartment top set air-conditioning system.But the deficiency of car top set air-conditioning system is also apparent at present, mainly has：(1) determine because it is mostly used
Frequency compressor easily causes the waste of the energy.(2) condensed water elimination existing defects, due to elevator be move up and down and movement away from
It is long from very, condensed water cannot be discharged outside lift car using a drainpipe as domestic air conditioner；And it is directly arranged
Enter hoistway and will produce huge security risk, therefore, how preferably to handle the technological difficulties that condensed water is current air conditioner for elevator.
(3) use ajutage to blow, the resistance not only blown is larger, but also also bigger by the loss of refrigeration capacity of ajutage, influences air-conditioning
Overall performance.(4), using return air inlet is directly opened on air-conditioning box, such air return method easily causes air volume adjustment unevenness, reduces and steam
Send out the heat exchange efficiency of device.(5) on the same face, evaporator front face area is smaller for air outlet and return air inlet, may cause heat exchange amount
It is insufficient.(6) a kind of removal condensed water mode is mostly used, when condensation water quantity is excessive, can cause condensed water that cannot remove in time, exist
Security risk.
In view of the above-mentioned problems, people also proposed a variety of solutions in research.Chinese patent literature CN202254191U
A kind of " air conditioner for elevator " is disclosed, it drives high-speed rotating wheel of fetching water using motor of fetching water, and condensed water is got on condenser,
Utilize the heat of vaporization condensed water of condenser.But since wheel of fetching water cannot be contacted with water-accepting tank bottom, it is difficult to which condensed water is complete
Portion begins to fight, be easy to cause water-accepting tank ponding, it is mouldy situations such as；Further, since the water that wheel is begun to fight of fetching water cannot be atomized, water
Particle is larger, and the heat of condenser cannot all evaporate the condensed water begun to fight, and leads to the air draft band water of condenser, causes cold
Condenser side water sinuous flow or seeping phenomenon.Chinese patent literature CN202915534U discloses a kind of " elevator sky with atomizer
Adjust ", the condensed water generated is expelled directly out after being atomized by atomizer, although this method solves evaporator water-accepting tank ponding
The problem of, if but presence condensation water quantity it is big when, the high temperature heat of condenser is difficult to the water droplet that will be atomized and all gasifies, and can make
At condenser side water sinuous flow or seeping phenomenon, and when condensation water quantity is few, the phenomenon that atomizer pump cisco unity malfunction.Chinese patent
Document CN203349465U discloses a kind of " air conditioner condensate water removal device and the integrated air conditioner with the device ", it belongs to
Integrated air conditioner is to make its evaporation using U-shaped exhaust pipe heating condensate water.But due to compressor air-discharging pipeline inner refrigerant
Thermal Finite, this integrated air conditioner can only work when condensing capacity is seldom, sultry wet weather, condensing capacity compared with
Its effect is very limited when big, cannot be fully solved the emission problem of condensed water.
