Description

The water saving indoor apparatus of air conditioner

The utility model relates to a kind of indoor apparatus of air conditioner, relates in particular to a kind of indoor apparatus of air conditioner of making low-temperature receiver with nature cold water.

Existing cold water indoor apparatus of air conditioner mainly is made up of casing, electric fan, feed pipe, valve, water drenching device, mistake water filtering layer, drainpipe, control electricity circuit etc.; Its function is exactly to blow out after making indoor hot-air through the cooling of water filtering layer.There is following defective in this indoor set, (1) there is not good confluent control device, confluent is difficult to control reasonably and easily, especially can not supply with corresponding cool water quantity with the rotation speed change of fan automatically, the waste and the waste of electric energy of cold water have so just been caused, when valve close big or small confluent very little the time, can cause the air-conditioning indoor relative humidity to raise.(2) new air access to plant is not set, indoor so required fresh air can only enter from door, window seam or other blow vent, door and window can not close too sternly like this, use inconvenient, fresh hot air does not have the concentrated area to pass through to contact with water in the machine, allow water siphon away more heat, cold water can not be made full use of.

The purpose of this utility model is that a kind of automatic water saving device that has is provided on the basis of above-mentioned cold water indoor apparatus of air conditioner, and the water saving indoor apparatus of air conditioner of new air inlet port and new air blast pipe is arranged.Make people use, easy to operate, can be under the condition of different water supply pressures, according to water temperature, rotation speed of the fan is supplied with the corresponding water yield, thereby the reduce water consumption outdoor fresh air enters machine in that contacting with water lowers the temperature and filter behind the dirt in the inlet chamber through new air blast pipe (drainpipe of holding concurrently), new air inlet port.

The utility model is to realize like this, on the feed pipe of cold water indoor apparatus of air conditioner, install 1 throttling pump additional, adorn 1 belt pulley on the power shaft of throttling pump, output shaft one end of fan electromotor also is equipped with 1 belt pulley, load onto 1 driving belt between these 2 belt pulleys, the rotating speed of throttling pump changes with the fan rotating speed of motor like this, be that confluent and air quantity of fan are synchronous, load onto the belt pulley of different-diameter or the throttling pump of different size just can automatically be supplied with the rational water yield according to the different water temperature in various places.At air suction inlet place, the bottom of this machine new air inlet port is housed, new air inlet port is connected with new air blast pipe to the air conditioning chamber; Water is also drained from new air inlet port and new air blast pipe.The suction that utilizes outdoor natural ventilation pressure and machine internal fan to produce like this makes outdoor new air, through lowering the temperature, filter the dirt after-blow to indoor.

Above-mentioned throttling pump preferably adopts gear pump, compares with the pump of other structure, and the influence that the gear pump flow is changed by water-feeding pressure is smaller, and the output ratio of precision is higher.

In order to make air with mistake water filtering layer the most comprehensive the contact be arranged, room air inlet port and new air blast pipe preferably all are arranged on motor spindle.

In order to make water and new air that bigger contact area be arranged, new air blast pipe can be made square, and making the airduct bottom surface is the plane.

The utility model increases on feed pipe adorns 1 throttling pump, and (this machine adopt gear pump), and throttling pump and fan electromotor are rotated synchronously with transmission mechanism, easily realized the automation of confluent control, saved water consumption, make operation can realize shaking control fully.The outer water pump of machine directly supplies water or high-level tank water, hydraulic pressure is all arranged, at this moment the pressure of water can promote the rotation of throttling pump, by transmission mechanism power be passed to fan electromotor, made full use of water pressure, open the fan motor that blows in again after magnetic valve water flowing several seconds during start earlier, can reduce the starting current of fan electromotor.New air inlet port and new air blast pipe have been installed to outdoor in this machine bottom, water is also drained from new air blast pipe, the suction that utilizes the running of outdoor natural ventilation pressure and machine internal fan to produce like this, make outdoor new air through cooling, blow to indoor behind the filter dirt by fan, make indoor new air-distribution even, new hot-air contacts with the water of soon discharging, can make the water intensification of further absorbing heat, outdoor new hot-air and indoor air temperature difference heat partly in the inlet chamber have been taken away, overcome in the direct inlet chamber of new hot-air, and the water water temperature of draining can not be higher than indoor air temperature, take away the few defective of heat, this point is in the air-conditioning place of the more resh air requirement of the intensive needs of personnel, and is particularly important.
