Abstract
The utility model provides an escalator air conditioner with a failure display, characterized in that: an exhaust port of a compressor is connected with a condenser, while a condenser draught fan is arranged on the condenser and an exit end of the condenser is connected with an entrance end of the evaporator through a capillary tube. An evaporator draught fan is arranged on the evaporator, while the exit end of the evaporator is connected with the aspirating port of the compressor. The exit end of the condenser is provided with a temperature sensor T 1 that is electrically connected with the computer CPT joint, while the entrance end of the evaporator is provided with a temperature sensor T 2 that is electrically connected with the computer CNG joint. A remote-control receiver that is connected with the lead of the computer board is also additionally provided with a twinkling indicator light under the control of the computer failure diagnosing program. Three different twinkles of the indicator light can display such failures as frost formation, less fluorine, no fluorine, and filth blockage of the condenser so as to greatly facilitate the working personnel to repair and maintain the escalator air conditioner. The utility model has the advantages of simple structure and easy effectiveness.
Description
Technical field
The utility model belongs to a kind of air conditioner for elevator that is used for lift car, particularly relates to a kind of air conditioner for elevator that fault shows that has.
Background technology
Known air conditioner for elevator is made up of compressor, condenser, condenser fan, capillary, evaporimeter and evaporator fan, and they are installed in the outer top of lift car, and the computer plate receiver of remote-control sytem that control is handled is installed on the lift car inwall.But in air conditioner for elevator used, the elevator management personnel can't see air conditioner for elevator ruuning situation.In a single day air conditioner for elevator breaks down, as: evaporimeter frosting, cold-producing medium leak, problem such as the dirty stifled and condenser fan fault of condenser, can not understand failure cause at once, so often cause air conditioner for elevator to turn round under abnormal state, not only refrigeration is bad but also easily air conditioner for elevator is caused more severe impairment.
Summary of the invention
The utility model provides a kind of maintenance, maintenance to have the air conditioner for elevator that fault shows more easily for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The utility model is made up of with the receiver of remote-control sytem that is connected with computer plate lead the computer plate of compressor, condenser and condenser fan, capillary, evaporimeter and evaporator fan and electrical control, the entrance point of condenser connects the exhaust outlet of compressor, the port of export of condenser connects the entrance point of evaporimeter by capillary, the port of export of evaporimeter connects the air entry of compressor, it is characterized in that: the port of export of described condenser is installed a temperature sensor T
1, temperature sensor T
1Output connect the CPT interface of computer plate; The entrance point of described evaporimeter is installed a temperature sensor T
2, temperature sensor T
2Output connect the CNG interface of computer plate; Indicator lamp by the sparkling demonstration of computer control also is installed on the described receiver of remote-control sytem.
Advantage and the good effect that the utlity model has are: owing at the evaporator end temperature sensor T who is electrically connected with computerized version CNG interface is installed
2And at temperature sensor T1 who is electrically connected with computer plate CPT interface of condensator outlet end installation, thereby computer can judge that evaporimeter frosting, cold-producing medium leak according to fault diagnostic program, the dirty fault such as stifled of condenser, and show by flashing indicator light, greatly facilitate maintenance and the maintenance of staff to air conditioner for elevator, improved the service life of air conditioner for elevator, in addition, advantage simple in structure, that be easy to realize that the utility model also has.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Label among the figure is respectively: the 1-compressor; 2-computer plate; The 3-indicator lamp; The 4-condenser fan; The 5-condenser; The 6-capillary; The 7-evaporimeter; The 8-evaporator fan; The 9-receiver of remote-control sytem.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, compressor 1 exhaust outlet connects the entrance point of condenser 5, the back side of condenser is equipped with condenser fan 4, the port of export of condenser connects the entrance point of evaporimeter 7 by capillary 6, the back side of evaporimeter is equipped with evaporator fan 8, and the port of export of evaporimeter connects the air entry of compressor.For fear of with control frosting, few fluorine, floride-free fault, at the evaporator end temperature sensor T2 is installed, the output of this sensor T2 connects the CNG interface of computer plate 2, with the indicator lamp 3 that also adds the control of computer glitch diagnostic program on the receiver of remote-control sytem 9 that computer plate lead is connected, this temperature sensor T2 has two functions: 1. when compressor start after 4 minutes and compressor when working long hours herein temperature should be higher than-4 ℃, otherwise computer judges, the instruction compression machine quits work, instructing lamp dodges secondary per 5 seconds continuously simultaneously, represents frosting or few fluorine; 2. when compressor start 5 minutes, this place's temperature variation should be greater than 5 ℃, otherwise computer judges, and the instruction compression machine quits work, and instructing lamp dodges three times per 5 seconds continuously simultaneously, and expression free-floride or compressor are not worked.For fear of with dirty stifled, the condenser fan of control condenser job failure not, at condenser delivery outlet end a temperature sensor T1 is installed, the output of this sensor T1 connects the CPT interface of computer plate 2, this temperature sensor T
1Function be: when this temperature 〉=62 ℃, computer judges, and sends instruction and stops compressor operating, and instructing lamp dodges four times per 5 seconds continuously simultaneously, and the dirty stifled or condenser motor of expression condenser is out of order and influence condenser and dispel the heat.By the demonstration of above-mentioned 3 clock indicator lamps, can tell directly that the staff finds out the air conditioner for elevator guilty culprit, keep in repair very convenient.
