Problems solved by technology

But in a high temperature environment, the compressor will only work for about 30 minutes after reset, and the overheating protection will occur again
In this way, the temperature in the elevator car rises rapidly during the long-term overheating protection period of the compressor, which makes the passengers extremely hot and seriously affects the normal use of the elevator.

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

technical field [0001] The invention belongs to an elevator air conditioner used for an elevator car, in particular to a high temperature resistant elevator air conditioner. Background technique [0002] The known special air conditioner for elevators is an ordinary air conditioner, and its structure is: a condenser with a fan is connected to the exhaust port of the compressor, the outlet end of the condenser is connected to the evaporator with a fan through a capillary tube, and the outlet end of the evaporator is connected to the compressor suction port. The maximum ambient temperature allowed by this ordinary air conditioner is 43°C, but the maximum ambient temperature in the sightseeing elevator shaft outside the building is usually between 48°C and 52°C (field measurements in Changzhou, Chongqing, Shenzhen and other places), At this temperature, the compressor of an ordinary air conditioner often suffers from overheating protection. Once the overheating protection occ...
