Cold and warm air conditioner on crane without independant engine

Abstract

An air conditioner of hot and cold with no independent engine for up locomotive of crane has a main machine which includes support frame, electromagnetic clutch, one-way hydraulic motor, hydraulic oil pump of heating, overflow valve of heating, compressor of refrigeration, condenser, reservoir. There will be the electromagnetic clutch to be connected in the support frame as one end connected with the one way hydraulic motor and hydraulic oil pump in series and another end connected with the compressor of refrigeration. One side of the support frame will be connected with the condenser and another side with the reservoir at its upper part. The main machine will connect with radiator which is connected with temperature control valve on it through piping and the main machine is controlled by the hydraulic controller.

Description

technical field [0001] The invention relates to an air conditioner used in an engineering vehicle control room, in particular to a cold and hot air conditioner without an independent engine in a crane control room. Background technique [0002] At present, there are two types of air conditioners for crane control rooms (without independent engines) at home and abroad. One is a single-cooling air conditioner in which a hydraulic motor directly drives a refrigeration compressor through a coupling or a pulley. When heating, an additional set of fuel heater is required to realize heating. The heating and cooling of the air conditioner are two independent systems, and the manufacturing cost is high; the other is to use the off-car engine as the power source to drive a high-power generator to generate electricity , through the central rotary brush to drive the motor to directly drive the compressor to work as refrigeration, and rely on the thermal eff...

[0002] At present, there are two types of air conditioners for crane control rooms (without independent engines) at home and abroad. One is a single-cooling air conditioner in which a hydraulic motor directly drives a refrigeration compressor through a coupling or a pulley. When heating, an additional set of fuel heater is required to realize heating. The heating and cooling of the air conditioner are two independent systems, and the manufacturing cost is high; the other is to use the off-car engine as the power source to drive a high-power generator to generate electricity , through the central rotary brush to drive the motor to directly drive the compressor to work as refrigeration, and rely on the thermal effect of the resistance wire to heat. This kind of air conditioner cannot be used due to the insufficient power and low power of the generator when cooling and heating. To meet the requirements of refrigeration and heating, in addition, the original crane circuit system must be modified to a large extent, the installation is cumbersome, and the cooling or heating cannot pass a large current for a long time due to the manufacture of the electric slip ring structure and other reasons, and cannot be put into use
