Description
Technical field
The present invention relates to air-conditioning, relate more specifically to a kind of technology of testing air conditioner.
Background technology
Air-conditioning usually refers to a kind of for example equipment of residential district, restaurant or office of the interior space that freezes or heat.Recently, in order more effectively to freeze or to heat the interior space that is divided into a plurality of rooms, developed a kind of technology of using an air-conditioning to freeze respectively or heating a plurality of rooms.
Generally speaking, air-conditioning can be divided into split type that indoor unit and outdoor unit are separated from each other and are provided with, and indoor unit and the integrally formed integral type of outdoor unit.Air-conditioning also can be divided into an indoor unit and be connected to the isolated of an outdoor unit and be installed in a plurality of indoor units in each room are connected to an outdoor unit jointly by network compound (multi-type).
Simultaneously, when installing an air-conditioner because the misconnection that pipeline and circuit take place easily for complicated piping arrangement (piping) and distribution.In view of this, when installing an air-conditioner, to test usually air-conditioning.For example, under indoor unit and outdoor unit are separated from each other the situation of the split-type air conditioner that is provided with, be connected to each other installing an air-conditioner in order to make indoor unit and outdoor unit, need be after separating distribution the separating pipe layout.Be connected at a plurality of indoor units under the situation of compound air conditioner of an outdoor unit, in order to install an air-conditioner, indoor unit must be connected to outdoor unit exactly by corresponding line connector of outdoor unit and corresponding auxiliary valve.Further, must the additional processing of carrying out the piping arrangement that separates.If install an air-conditioner by this way, then need air-conditioning is tested.That is to say, the whole service of air-conditioning is tested.
The following description that will provide the problem of the legacy system that is used for testing air conditioner with reference to Fig. 1.In order to understand the problem of legacy system better, suppose that here air-conditioning is split type and compound.
Setter is installed the indoor unit of the air-conditioning of the outdoor unit of air-conditioning of buildings outside and this interior of building respectively, tests this air-conditioning then.In order to test this air-conditioning, for example, setter must move this indoor indoor unit to check the running status of this indoor unit, the running status of removing outdoor this outdoor unit of inspection then.
In order to address this problem, the test procedure of installing and moving has been proposed in the test terminal of air-conditioning outside.For example, this setter makes this outdoor unit and this test terminal be connected to each other in this mode that they can communicate with one another, and moves test procedure then to check refrigerating/heating running status and the wiring between outdoor and the indoor unit and the state of piping arrangement of outdoor unit and indoor unit in this test terminal.
Yet, in traditional test macro, outdoor unit and indoor unit for testing air conditioner, setter is pulled down the front panel of this outdoor unit from the main body of this outdoor unit, this outdoor unit represents that with Reference numeral 101 main body of the circuit box from this outdoor unit 101 is pulled down the lid of this circuit box then.Then, setter is connected to a plug of anchor clamps cable (jig cable) 103 operation/unit of testing and controlling the (not shown) of this circuit box.This anchor clamps cable 103 that is connected to this outdoor unit 101 is generally 15 to 20 meters long.
This air-conditioning can be supported any communication protocol.For example, this air-conditioning can be supported RS-485 communication protocol.In this case, the RS-485 communication port can be arranged in this operation/unit of testing and controlling or with this control module branch and be arranged.
Similarly, any communication protocol of communicating with other external unit can be supported in this test terminal 109.For example, this communication protocol can be serial communication protocol and USB (universal serial bus) (USB) agreement.The communication protocol that this air-conditioning and this test terminal 109 are supported can differ from one another usually.
The shortcoming of above-mentioned legacy test system is: for testing air conditioner, setter must be carried to this anchor clamps cable 103 place at these outdoor unit 101 places, pull down the front panel of this outdoor unit 101 from the main body of this outdoor unit 101, pull down the lid of this circuit box then from the main body of this circuit box, then this anchor clamps cable 103 is connected to this operation/unit of testing and controlling, this is very inconvenient to setter.Further, to such an extent as to too heavy, too complicated be difficult to a plurality of equipments of installing for example cable 103, cable 107 and converter 105 must be arranged in this legacy test system, and it is pretty troublesome that these equipments are installed.
In addition, there is restriction in this legacy test system aspect the length of this anchor clamps cable 103 and serial cable 107.For this reason, for example, under this outdoor unit and a plurality of indoor unit situation away from each other, because the restriction of communication distance between this outdoor unit and a plurality of indoor unit may cause test result information to become unstable.For addressing this problem, setter must go outdoor the test, and this causes the inconvenience used.
Summary of the invention
Therefore, in view of above problem proposes the present invention, a purpose of the present invention provides a kind of improved technology that is used for testing air conditioner.
Another object of the present invention provides a kind of equipment that is used for testing air conditioner, wherein can reduce the cost and the manpower of installation testing equipment equipment.
