Abstract

The heat resistant air conditioner for elevator includes compressor, condenser connected to the exhaust port of the compressor, condenser blower in the back of the condenser, capillary tube connected to the outlet of the condenser, evaporator connected to the outlet of the capillary tube, and evaporator blower in the back of the evaporator. The heat resistant air conditioner features that it has one spare evaporator, which consists of one copper tube bank to the back of the condenser and has inlet connected through one normally closed solenoid valve to the outlet of the capillary tube and outlet connected to the sucking port of the compressor; one normally opened solenoid valve installed between the outlet of the capillary tube and the evaporator inlet, and one pressure switch for controlling the solenoid valves installed to the compressor exhaust port, so that the spare evaporator may be thrown into the refrigerating loop in case of over high temperature.

Description

A kind of heat resistant air conditioner for elevator
Technical field
The invention belongs to a kind of air conditioner for elevator that is used for elevator cage, particularly relate to a kind of heat resistant air conditioner for elevator.
Background technology
Known elevator special air conditioner is a common air-conditioning, and its structure is: the exhaust outlet at compressor connects the condenser that has blower fan, and the port of export of condenser connects the evaporimeter that has blower fan by capillary, and the port of export of evaporimeter connects the air entry of compressor.The high ambient temperature that this common air-conditioning allows is 43 ℃; but outside the building the high ambient temperature in the sightseeing elevator hoistway of side is generally between 48 ℃-52 ℃ (in Changzhou, ground field survey results such as Chongqing, Shenzhen), and the overtemperature protection phenomenon often takes place the compressor of common air-conditioning under this temperature.In case the generation overtemperature protection, its overtemperature protections in about 2 hours such as need just can reset.But under hot environment, overtemperature protection can take place again in only about 30 minutes in the back compressor operating that resets again.Temperature in like this during the long overtemperature protection of compressor in the elevator cage raises rapidly, makes passenger's backing hot, seriously influences the normal use of elevator.
Summary of the invention
The present invention provides a kind of heat resistant air conditioner for elevator that is suitable for the sightseeing elevator hot environment for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of heat resistant air conditioner for elevator, by compressor, connect capillary that exhaust outlet of compressor has the condenser of fin and condenser fan thereof, connection condensator outlet end, connect evaporimeter and the evaporator fan thereof that capillary outlet end and compressor air suction mouth have fin and form, the standby evaporimeter that is made of row's copper pipe also is installed in the fin at the described condenser back side, the port of export of standby evaporimeter connects the air entry of compressor, the arrival end of standby evaporimeter is equipped with normally closed solenoid valve, and the other end of normally closed solenoid valve connects the port of export capillaceous; Also be serially connected with normally open solenoid valve between described capillary outlet end and the evaporator inlet end; Described exhaust outlet of compressor also is equipped with pressure switch.
The present invention can also adopt following technical measures:
One electric control end of described pressure switch connects compressor electrical input binding post R, another electric control end of pressure switch connects the electric control end of normally open solenoid valve and the electric control end of normally closed solenoid valve, and another electric control end of normally open solenoid valve and normally closed solenoid valve is connected another electrical input binding post of compressor C.
The advantage that the present invention has with good effect is: owing to add the standby evaporimeter that is connected with the compressor air suction mouth with capillary outlet in the fin at the condenser back side; arrival end at standby evaporimeter is equipped with normally closed solenoid valve; add normally open solenoid valve at former evaporator inlet end; and exhaust outlet of compressor install additional control two magnetic valves work the pressure switch of closing; like this under high-temperature condition; control by pressure switch; enable the standby evaporimeter on the condenser; close original evaporimeter; condenser pressure is descended rapidly; after this pressure switch resets very soon; original evaporimeter that returns to normal condition has been avoided the generation of overheat of compressor protection, guarantees compressor continuous operation and normal refrigeration; thereby the temperature in the assurance elevator cage is comfortable nice and cool, and the present invention also has simple in structure; the advantage that is easy to realize.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is standby evaporimeter of the present invention and condenser scheme of installation;
Fig. 3 is circuit theory diagrams.
Among the figure: 1 compressor, 2 pressure switches, 3 condenser fans, 4 standby evaporimeters, 5 condensers, 6 fin, 7 capillaries, 8 normally closed solenoid valves, 9 normally open solenoid valves, 10 evaporimeters, 11 fin, 12 evaporator fans.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the exhaust outlet of compressor 1 connects the condenser 5 that has fin 6 by pressure switch 2, the condenser rear side is equipped with condenser fan 3, the port of export of condenser is connected with capillary 7, the port of export capillaceous is connected with normally open solenoid valve 9 and normally closed solenoid valve 8 simultaneously by a three-way pipe, the other end of normally open solenoid valve connects the arrival end of the evaporimeter 10 that has fin 11, the rear side of evaporimeter is equipped with evaporator fan 12, the other end of normally closed solenoid valve connects the arrival end of standby evaporimeter 4, standby evaporimeter is made of row's copper pipe, it is installed in the fin 6 at the condenser back side, as shown in Figure 2, the port of export of evaporimeter and standby evaporator outlet end are connected the air entry of compressor simultaneously by a three-way pipe.Pressure switch is electrically connected as shown in Figure 3 with normally open solenoid valve and normally closed solenoid valve, the electrical input R of compressor connects the electric control end of pressure switch 2, another electric control end of pressure switch connects an electric control end of normally open solenoid valve 9 and normally closed solenoid valve 8 simultaneously, and another electric control end of normally open solenoid valve 9 and normally closed solenoid valve 8 is connected the electrical input C of compressor simultaneously.
Operation principle of the present invention is:
After compressor 1 started, condenser pressure was lower than 27kg/cm 2The time, pressure switch 2 is in off state, normally open solenoid valve 9 and normally closed solenoid valve 8 no powers, and cold-producing medium flows back to compressor through condenser, capillary, evaporimeter, normal refrigeration; When environment temperature too high (56 ℃-58 ℃), condenser pressure is greater than 27kg/cm 2The time, pressure switch closure (connection), normally open solenoid valve cuts out, normally closed solenoid valve is opened, this moment, cold-producing medium flowed back to compressor through condenser, capillary, standby evaporimeter, and standby evaporimeter descends (about about 15 seconds) condenser pressure rapidly, when condenser pressure is reduced to 26kg/cm 2The time, pressure switch resets (opening circuit), the normally open solenoid valve conducting, and normally closed solenoid valve is closed, and cold-producing medium recovers normal circulation, continues the elevator cage refrigeration is kept the comfort temperature in the cab.
