Abstract
The utility model relates to an air feeding system for a vehicle air conditioner, and belongs to the technical field of vehicle air conditioners. The utility model mainly resolves the problem that the air feeding distance of an internal machine in an air-condition chamber of various square cabins and field operating vehicles is short with only 3 m and that the requirement of a design of 6 m can not be reached. The utility model is mainly characterized in that the air feeding system comprises a cross-flow fan and an air channel. The cross-flow fan includes a cross-flow wind wheel and a direct-current motor, and a direct-current power circuit is also arranged. The rotate speed of the fan can be adjusted to increase by 2 times and the power of the fan can be increased by 2 times without increasing the space position which is taken up by the cross-flow fan. So the air feeding distance can reach more than 6 m. The utility model is mainly used for various square cabins and field operating vehicles, and is more particularly used to an air feeding system for a separate air-condition of a narrow and long field operating vehicle.
Description
Technical field
The utility model belongs to the on-board air conditioner technical field, relates to the supply air system of on-board air conditioner, particularly a kind of on-board air conditioner supply air system that adopts alternating-current power supply.
Background technology
At present, various shelters and field work automobile wagon envelope such as long and narrow envelope are equipped with multiple instrument and equipment in it, adopt 230v, 50HZ ac power supply.For the normal operation that guarantees instrument and equipment with improve staff's operating environment, need configuration one cover split-type air conditioner, be subjected to the restriction in envelope space, the indoor set of air-conditioning can only be installed on the envelope fixed position, compartment.Because compartment envelope size is fixed, so just limited the length and width size of indoor set, finally limited and exchanged the shared locus of cross flow fan, make the air supplying distance maximum of the interchange cross flow fan of being matched have only 3 meters, thereby, cause the local cold of close indoor set in the long and narrow envelope, away from the local heat of indoor set, temperature is extremely inhomogeneous in the whole envelope, influences instrument and normally uses.
Summary of the invention
The purpose of this utility model provides a kind of air supplying distance can reach 6 meters at above-mentioned weak point exactly, can make the interior temperature of envelope even, the A/C supply air system that thermoregulation effect is good.
Technical solution of the present utility model is: a kind of air condition with camion supply air system, comprise cross flow fan and air channel, and it is characterized in that: described cross flow fan is made of tubular wine wheel and DC machine, and is provided with DC power supply circuit.
DC machine described in the utility model technical solution can be to be inlaid on the indoor set of separate type air conditioner.
The utility model is owing to adopt DC machine and DC power supply circuit, thereby source of AC can be transformed into direct supply and power to DC machine, under the situation that does not increase the shared locus of through-flow motor, can adjust and make motor speed improve 2 times, power improves 2 times, so just can guarantee that air supplying distance reaches more than 6 meters, make the interior temperature of long and narrow envelope even, thermoregulation effect is good.The utility model has overcome the power and the rotating speed that will improve alternating current dynamo in the prior art, certainly will increase and change the oad of motor, wind wheel, and the increase of motor, wind wheel oad and change can't be satisfied the weak point of the designing requirement of indoor set, thereby have reached the purpose of this utility model.
Description of drawings
Fig. 1 is the scheme drawing of the utility model running condition; Fig. 2 is a circuit diagram of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2.Tubular wine wheel and DC machine 6 constitute cross flow fan.Cross flow fan and air channel constitute the supply air system of A/C, are arranged in the indoor apparatus of air conditioner 2.The detachable air conditioner that adopts the utility model and constitute is applicable to various shelters and field work van, such as the long and narrow envelope 3 of horizontal positioned.Off-premises station 1 is installed on the outer wall between envelope 3 and the headstock, and indoor set 2 is installed on the inwall of envelope 3.The utility model DC power supply circuit 5 adopts bridge inverter main circuit 5, is made up of voltage transformer, bridge rectifier and filter, direct supply is provided for DC machine 6.Bridge inverter main circuit 5 is powered by vehicle-mounted source of AC 4, and is controlled by the single chip machine controlling circuit 7 and the relay 8 of air-conditioning.After the supply air system that employing is made of DC machine 6, bridge inverter main circuit 5 and air channel, under the situation that does not increase the shared locus of cross flow fan, can adjust and make rotation speed of fan improve 2 times, power improves 2 times, can guarantee that like this air supplying distance reaches more than 6 meters, make cool breeze form circulation in greater than 7 meters long and narrow envelope 3 whole spaces, thermoregulation effect is good, and temperature is even.
Claims (2)
