Problems solved by technology

This not only increases the burden on the engine, increases the fuel consumption of air-conditioned vehicles and the emission of exhaust gas, but also causes heat pollution caused by the condensation and exhaust heat of the air-conditioning unit.
At the same time, due to the complex structure of the existing vehicle air-conditioning and refrigeration devices, one or the other faults often occur, which brings a lot of trouble to the maintenance.

Embodiment Construction

[0008] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0009] Such as figure 1 As shown, the present invention mainly includes an ice storage tank 1, a drain valve 2, a circulating water pump 3, a coil heat exchanger 4, a condensed water drain pipe 5, an axial flow fan 6, a circulating water pipe 7, an expansion tank 8, and a three-way valve 9 , Expansion water pipe 10.

[0010] The ice storage tank 1 is a rectangular box made of heat-insulating material. A movable cover is installed on the top of the box to add ice cubes. A drain valve 2 is installed at the bottom of the ice storage tank 1 to discharge excess The ice storage tank 1 can be positioned at the vacant place at the rear of the bus or under the passenger seat. One end of the circulating water pipe 7 is connected to the pipe side outlet of the coil heat exchanger 4, the other end passes through the ice storage tank 1, and is conne...

Abstract

The invention discloses an ice cold accumulation supplying cold equipment of city bus including accumulation ice trough, draining valve, circulating pump, scroll heat exchanger, condensate drainpipe, screw type ventilator, circulating pipe, expansion tank, triple valve and expansion pipe. The equipment is no compressor, using miniwatt circulating pump to conquer flow resistance of secondary refrigerant circulating pipe and scroll heat exchanger, secondary refrigerant circulating pipe is drove by circulating pump and transport the energy of accumulation ice trough to scroll heat exchanger, the heat air in the bus flows along scroll heat exchanger shell pass, then be cooled by scroll heat exchanger to deliver into bus, so bus indoor cooling realized. The ice is supplied by ice house utilizing low-cost night electric energy to release bus engine load, induce tail gas discharge and no condensation heat extraction. The equipment is character by simple structure, environmental protection, low cost, easy fixing and so on.

Description

technical field [0001] The invention relates to an ice-storage air-conditioning cooling device, in particular to an ice-storage air-conditioning cooling device for urban buses, belonging to the technical field of air-conditioning refrigeration and vehicle equipment engineering.
