Abstract
The present invention is aimed at providing a frequency-fixed multiple air-conditioning machine unit. Said frequency-fixed multiple air-conditioning machine unit only has need of using one outdoor machine to meet application requirements of indoor machines with different types. Said outdoor machine can effectively control refrigerant flow rate, and on the outdoor machine a controller is set, said controller is connected with an electronic expansion valve, and said outdoor machine is connected with the indoor machine with main board chip by means of preset ID signal communication.
Description
Technical field:
The present invention relates to the collocation technology of indoor apparatus of air conditioner and off-premises station, specially refer to a kind of collocation technology of fixed-frequency multi-gang formula air-conditioning unit.
Background technology:
The old times king thanks to a preceding swallow, flies into common people house.Air-conditioning has not been any luxury goods in the society of today already, and along with being extensive use of of air-conditioning, people are also more and more higher to the requirement of air-conditioning, the air-conditioning of come in every shape, power is different appearing in one's mind in face of the consumer like the mushrooms after rain.Characteristics such as wherein the fixed-frequency multi-gang air-conditioning unit that can join many indoor sets simultaneously by an off-premises station is with the reliability height, and power consumption is few are favored by fastidious consumer gradually.But use the people of fixed-frequency multi-gang air-conditioning unit still to have a question: because people's aesthetic conceptions and personal like's is different, different people is also different to the selection of indoor set type, wall-hanging or cabinet-type or other pattern power, so, the fixed-frequency multi-gang unit of air-conditioning manufacturer production certainly will will produce the off-premises station of many money couplings in order to meet the need of market.How can design the instructions for use that a off-premises station satisfies different indoor sets simultaneously is exactly the problem to be solved in the present invention.
Summary of the invention:
The object of the present invention is to provide a kind of fixed-frequency multi-gang air-conditioning unit, this fixed-frequency multi-gang unit only need use a off-premises station can satisfy the instructions for use of the different indoor set of type, this off-premises station can effectively be controlled cold medium flux, realizes the conversion of a plurality of indoor sets and effective coupling of system loading.
The object of the present invention is achieved like this: a kind of fixed-frequency multi-gang air-conditioning unit, comprise the off-premises station that compressor, outdoor heat converter etc. are formed, a plurality of indoor sets and be connected off-premises station and indoor set between pipeline and power supply, described off-premises station is provided with a controller, be provided with the control chip that is provided with type aperture table in the controller, described controller has connected at least one electric expansion valve, and the controller of described off-premises station is connected by default ID communication with the indoor set that the mainboard chip is housed.
In the control chip of described controller with the electronic expansion valve opening of all off-premises stations.
The address code switch that the 2-5 position is arranged on the described indoor set mainboard chip.
The mainboard chip of described indoor set is provided with the type sign indicating number of expression air-conditioning type.
The mainboard chip of described indoor set is provided with the capacity sign indicating number of expression air-conditioning power.
Advantage of the present invention is: (one), system line are simple in structure, the operation, the operation convenient and reliable, operation cost is low, has very strong practicality.(2), this unit can effectively control cold medium flux, realizes that single off-premises station is to the running conversion of a plurality of indoor sets and effective coupling of system loading.(3), to add element in former air-conditioning system few, low cost of manufacture is easy to promote the use of.
Description of drawings:
Fig. 1 is inside and outside machine communication flow figure of the present invention;
Fig. 2 is embodiments of the invention one structural representation sketches;
Fig. 3 is the concrete control chart of embodiments of the invention one;
The specific embodiment:
As shown in Figure 1, 2:
Off-premises station adopts the form of invariable frequency compressor combination, the corresponding indoor set of one compressor, each indoor set all is independently, each indoor set all has own corresponding electric expansion valve 3 in off-premises station, an electronic expansion valve controls chip 2 is arranged in the off-premises station, and chip internal is with the electronic expansion valve opening of all types indoor set.Every kind of indoor set mainboard chip 4 has oneself type ID number, and 2～5 address code switch is arranged on the indoor set mainboard, when inside and outside machine communication, off-premises station is according to ID number of indoor set, judge the indoor set type such as the air-cooled ducted air conditioner that are connected, the courtyard machine, wall mounted machine, cabinet-type air conditioner etc., off-premises station electronic expansion valve controls device 1 finds corresponding electronic expansion valve opening according to indoor set capacity sign indicating number from the electronic expansion valve opening table simultaneously, drive electric expansion valve 3 and get to needed aperture, realized that different indoor sets have the process of different cold medium fluxes, the operational process of concrete off-premises station and indoor set is as follows:
(1), outdoor controller 1 prepares response, judges whether to receive the type sign indicating number from indoor set, if do not have, then continues to wait for to receive, if having, then enters next step;
(2), outdoor controller 1 reads the type sign indicating number that indoor set sends, and judges the indoor set type that is connected, and enters next step;
(3), outdoor controller continues to read the capacity sign indicating number on the indoor set mainboard chip 4, and finds corresponding electronic expansion valve opening according to this capacity sign indicating number from the electronic expansion valve opening table, enters next step;
(4), outdoor controller 1 drives electric expansion valve 3, it got to needed aperture, the control cold medium flux.
As shown in Figure 3, this unit has connected the interior machine of multiple model, during refrigeration, if the machine model was the indoor set of 65P/D in the consumer selected for use, at this moment outdoor controller 1 can judge that his type sign indicating number be that PD, capacity sign indicating number are 65, and to look for the aperture of 65 machine correspondences from all electronic expansion valve opening tables be B to controller then, drives 3 to the B steps of electric expansion valve, thereby flow system flow changes, and satisfies instructions for use.
Fixed-frequency multi-gang air-conditioning designed according to this invention, under the situation that air-conditioner outdoor unit is fixed, can select the indoor apparatus of air conditioner of different styles, different capacity according to the hobby of oneself arbitrarily, for having added new economize on electricity, fashion theory in the Air-conditioner design, in a large amount of uses of air-conditioning, reduced energy waste.
What need indicate is that the related personnel also belongs to protection scope of the present invention to any alteration of form or parts replacement that does not relate to basic structure and connected mode that the present invention makes.
