Abstract
The utility model discloses a compressor standby air conditioning unit, which comprises a relay switch, a time delay relay, a first compressor and a second compressor; the first compressor is connected to a mains supply end through the first contactor, and the second compressor is connected to the mains supply end through the second contactor; an output circuit of the first contactor is provided with an inductive current relay, an inductive current relay coil is used for detecting current of the output circuit of the first contactor, a normally open contact of the inductive current relay is connected with a relay switch coil in series and then connected with a mains supply end, and a relay switch and a normally open contact of the time delay relay are sequentially connected in series in a power supply loop of the second contactor. The air conditioning unit is only provided with the standby compressor on the basis of the original unit, and has low cost and high stability.
Description
Technical Field
The utility model belongs to the technical field of the air conditioning unit technique and specifically relates to a compressor standby type air conditioning unit is related to.
Background
In the air conditioning unit system, the compressor is the most important part, is equivalent to the heart of the whole system and plays the role of 'source power' of the whole system, so that the running stability of the compressor is important in the running of the unit, and the standby setting is carried out on the compressor, so that the running stability of the unit can be greatly improved. If the condition of unit standby is considered, the conventional air conditioning unit is generally realized by adding a set of complete unit, namely, a set of main components of the air conditioner, such as a compressor, a condenser, an evaporator, a throttling device and the like, are required, so that the investment cost is greatly increased, and a large space is occupied for placing the standby unit.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at the shortcoming of prior art, provide a compressor standby type air conditioning unit, only increase the standby compressor on the basis of original unit, with low costs, stability is high.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a compressor standby type air conditioning unit comprises a relay switch, a time delay relay, a first compressor and a second compressor; the first compressor is connected to a mains supply end through the first contactor, and the second compressor is connected to the mains supply end through the second contactor; an output circuit of the first contactor is provided with an inductive current relay, an inductive current relay coil is used for detecting current of the output circuit of the first contactor, a normally open contact of the inductive current relay is connected with a relay switch coil in series and then connected with a mains supply end, and a relay switch and a normally open contact of the time delay relay are sequentially connected in series in a power supply loop of the second contactor.
The utility model has the advantages that:
the utility model discloses increase a reserve equivalent compressor in original compressor circuit, all the other parts borrow former unit configuration completely, realize former compressor automatic switch-over to reserve compressor when the trouble, the operating stability of reinforcing unit has also reached the purpose of system economy and reserve nature.
Drawings
Fig. 1 is a schematic diagram of the compressor standby type air conditioning unit of the present invention.
In the figure: 1-contactor one, 2-contactor two, 3-current induction type relay, 4-relay switch, 5-time delay relay, 6-compressor one, 7-compressor two.
Detailed Description
The invention is further described with reference to the following figures and examples.
A compressor standby type air conditioning unit comprises a relay switch 4, a time delay relay 5, a first compressor 6 and a second compressor 7; the first compressor 6 is connected to a mains supply end through the first contactor 1, and the second compressor 7 is connected to the mains supply end through the second contactor 2; be equipped with induction type current relay 3 on the output line of contactor one 1, 3 coils of induction type current relay are used for detecting the output line electric current of contactor one 1, insert the commercial power supply end behind 3 normally open contacts series connection relay switch 4 coils of induction type current relay, and relay switch 4, delay relay 5 normally open contacts establish ties in the power supply circuit of contactor two 2 in proper order.
The specific working principle is as follows: the first contactor 1 and the second contactor 2 are contactors of a first compressor 6 and a second compressor 7 respectively and are used for controlling starting and stopping of the first compressor and the second compressor, and the current induction type relay 3 is an induction type relay and can induce current in a line between the first contactor 1 and the first compressor 6. After the L line is electrified, after the coil of the first contactor 1 is connected, the first contactor 1 is closed, the compressor 1 is started, and after the current induction type relay 3 senses current, the upper contact and the lower contact of the current induction type relay are conducted, so that the coil at the top of the relay switch 4 is electrified, the relay switch 4 is opened, and in a state shown by a dotted line in figure 1, the first compressor 6 is normally started, and the second compressor 7 circuit is not started.
If the first compressor 6 breaks down, the first contactor 1 does not output current any more, the current induction type relay 3 does not induce current at the moment, the coil at the top of the relay switch 4 cannot be electrified, the relay switch 4 can be restored to a closed state, the delay relay 5 is conducted at the moment, the control circuit of the second contactor 2 is correspondingly communicated, the second compressor 7 starts to work, and the second compressor 7, namely the standby compressor, is started, so that the normal operation of the whole unit is ensured.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
