Description

The water supply installation of water evaporation for cooling air conditioning for automobiles

Technical field

The utility model belongs to the vehicle technology field, is specifically related to the vehicle passenger cab refrigerating air-conditioner.

Background technology

Along with development of technology, by the water on the evaporation wet film, the air of the wet film of flowing through is the evaporation type air-conditioning that core constitutes, owing to have and in process of refrigerastion, force separate ventilation in the refrigeration space simultaneously, increase is by refrigerated air humidity, energy consumes advantages such as low, caused the concern of air conditioning for automobiles industry, and had air conditioning applications to occur in succession in the technical scheme of automobile guest room refrigeration with this kind refrigeration modes.Because the air conditioning applications of this kind refrigeration modes still belongs to the primary stage in the refrigeration of automobile guest room, has many inharmonious, imperfection parts, as the water treatment of evaporation water, storage, supply automatically, sprinkling amount and sprinkling rule also do not propose the corresponding techniques scheme.These problems do not solve, and certainly will influence the normal operation of whole water evaporating air conditioner, and refrigerating efficiency is had a greatly reduced quality.

Summary of the invention

The purpose of this utility model provides a kind of water supply installation of water evaporation for cooling air conditioning for automobiles, overcomes the aforementioned deficiency that exists in the supply of existing water evaporation for cooling air conditioning for automobiles water.

The water supply installation of water evaporation for cooling air conditioning for automobiles of the present utility model is by the main water box that stores water, and to the cyclic water tank that wet film supplies water, blowoff valve is pressed in pressure pump, storage, divides water solenoid valve and interconnective road pipe to form.Be useful on the filler pipe that connects tap water pipe line on main water box, have the highest in the main water box and the lowest water level sensor, level sensor control is contained in the water level indicator light that the driver and conductor sees the position easily.Cyclic water tank has the filling pipe that connects main water box, and magnetic valve is arranged on the filling pipe, and the level sensor of control moisturizing magnetic valve is arranged in the cyclic water tank.The cyclic water tank outlet pipe connects storage and presses blowoff valve and water pump, and storage presses blowoff valve to comprise that storage presses chamber and water flowing, blowdown to rotate and switch spool, and it is the enclosed cavity that there are water inlet and delivery port in the lower end that storage presses the storage on the blowoff valve to press the chamber.Be fixed with filter screen in the through hole on the dirty valve core of storage pressure, the spool rotation, through hole can correspondingly respectively pass the water channel and the storage of valve body and press the chamber to lead to the outer passage of valve body.Storage presses the chamber to connect pressure sensor, and storage presses the chamber delivery port to be mounted on the branch water row of evaporation wet film top by pipeline.On the pipeline between dirty method of storage pressure and the branch water row, the branch water solenoid valve of being pressed the pressure sensor control on the chamber by storage is arranged.

The course of work of the present utility model is: the filler pipe of main water box is connect water tap, add water to main water box, the peak level lamp is bright, stop to add water, add water first after, operation of air conditioner is to main water box lowest water level lamp when bright, repetition adds the process of water to main water box, and this process is controlled by sensor.When water level rises to the peak level sensor in the cyclic water tank, close the moisturizing magnetic valve, spool is driven by stepping motor, the programme-control that stepping motor is set.Start water pump, owing to divide water solenoid valve in off position, the pressure (hydraulic) water of water pump of flowing through is pressed the chamber inner accumulated in storage, compression is enclosed in into, the air of outlet pipe top, the space that air occupies dwindles gradually, pressure strengthens gradually, and when pressure during to the sensor settings value, storage presses blowoff valve to lead to divide the branch water solenoid valve on the water comb road open-minded, pressure (hydraulic) water is sprayed on the wet curtain through a minute water row, since divide water solenoid valve open-minded, the leaked water that storage presses the chamber to store, and storage presses cavity pressure to descend, pressure sensor cuts out shunt valve, the water pump that runs without interruption makes storage press the water in chamber to gather again, and storage presses the pressure in the chamber to increase again, during to setting value, open the branch water solenoid valve once more, divide water row to spray the evaporation water again, so repeatedly, keep the pulse water supply state of wet curtain.

In control program, be set at some hrs once by the accumulation clocking value, in pressing the chamber, storage pressurizes, but when the branch water solenoid valve is opened, rotary spool conducting storage presses the chamber to lead to the outer passage of valve body, press the water under high pressure in the chamber to wash filter screen in the other direction with storage, can remove the dirt that accumulates on the filter screen.Spool comes back to water channel automatically then.

Good effect of the present utility model is to provide a kind of simple in structure, all control automatically of realization to the evaporation type air-conditioning, and the water supply mechanism of water yield co-ordination of supply and demand is the condition created of applying of evaporation type air-conditioning.
