Abstract

The utility model discloses an automatic timing turning-on control device for an air-conditioning unit, in particular to a multi-period timing controller for the air conditioning unit in an equipment room. An automatic timing turning-on controller for the air-conditioning unit comprises a microcomputer time controller, two electronic time relays, a distribution box and assembly components. After the microcomputer time controller is used for setting periods for powering on the air conditioning unit, the electronic time relays form a dual time delay control circuit, through time delay setting of the time relays, certain preheating preparation time is provided for a computer motherboard of the air conditioning unit, then a start signal is sent to the air conditioner for turning on the air conditioner, and therefore the air conditioner is turned from a standby mode to an operation mode. The multi-period timing controller for the air conditioning unit in the equipment room has the advantages of having a multi-period timing turning-on and turning-off function, lowering labor cost, reducing energy waste, and the like.

Description

The multi-period timing controller of equipment machine room air-conditioning

Technical field

The utility model relates to a kind of power-supply controller of electric of electric equipment, and more particularly, the utility model relates to a kind of self-timing opening controller of air-conditioning equipment.Background technology

Expansion along with the estate management scale, the equipment machine room quantity of dominated project also increases gradually, management expectancy to equipment machine room is also more and more overcritical, for the operation of assurance equipment is no more than set point of temperature, need to control computer room temperature, and air-conditioning is exactly effective temperature controlling instruments, the opening and closing of air-conditioning are mostly by manually operating at present, for nearly tens of large-scale property project calculator room equipments, and be distributed in different positions, the air-conditioning open and close of every day need to spend a large amount of human costs, because manually-operated various factors, some air conditioner in machine room can not be accomplished in accordance with regulations open and close, and this just causes the waste of energy consumption and unnecessary expense expenditure.

Summary of the invention

The purpose of the present utility model is to overcome the deficiencies in the prior art, reduces energy consumption and human cost expenditure, increases economic efficiency and provides a kind of equipment machine room air-conditioning multi-period timing controller.

The purpose of the present utility model is achieved through the following technical solutions:

Consist of a kind of self-timing opening controller of air-conditioning equipment by microcomputer time controlled device, 2 of electronical time relays, distribution box and assembling fittings, the multi-period timing controller of equipment machine room air-conditioning forms the dual-delay control circuit by 2 electronical time relays.The microcomputer time controlled device is after the setting-up time section is to the air-conditioning plugged, the time relay forms the dual-delay control circuit by time relay delay adjustments, give the air-conditioning computer mainboard certain preheating time, and then to air-conditioning one enabling signal, open air-conditioning, allow air-conditioning be transformed into opening from holding state.

Technique scheme is done further to limit, and described microcomputer time-controlled switch is as the multi-period air conditioner power source switch that arranges.By the output of microcomputer time-controlled switch control power supply, its out-put supply is as the working power of air-conditioning, and this microcomputer time-controlled switch can carry out multi-period set of time control, as required at different time period open and close air-conditionings.

Compared with prior art, the utlity model has following beneficial effect:

1. reach the purpose that the multi-period time opening of air-conditioning is closed;

2. reduce human cost, reduced the waste of energy consumption.

Fig. 2 is air-conditioning automatic control circuit figure;

The specific embodiment

Below in conjunction with drawings and Examples essentiality content of the present utility model is described in further detail:

As shown in the figure: by the microcomputer time controlled device, 2 of electronical time relays, distribution box and assembling fittings consist of a kind of self-timing opening controller of air-conditioning equipment, select 1 microcomputer time-controlled switch (model KG316T) as the power switch of air-conditioning, because its rated current can reach 20A, so not needing to add in addition auxiliary contactor controls, this microcomputer time controlled device has arrange 16 groups of multi-period switch times, can carry out multi-period time control, select 2 electronical time relays (model: SP3PA-A) as the time time-delay of air-conditioning self-starting and the input of enabling signal, when microcomputer time-controlled switch moves in the setting-up time section, in the air-conditioning equipment power supply, also provide power supply to control circuit, the phase line power supply makes coil KT1 energising by the KT2 normally-closed contact, KT1 coil electricity time-delay adhesive makes the KT1 normally opened contact closed, its objective is to make and make delayed start-up behind the air-conditioning plugged and prepare, it is electric simultaneously to enabling signal of major loop that KT1 normally opened contact closure gets the KT2 coil, the time delays action of coil KT2 through setting, the KT2 normally opened contact is closed, the KT2 normally opened contact makes the self-locking of KT2 coil, the KT2 normally-closed contact cuts off rapidly the enabling signal to major loop simultaneously, reaches the automatically actuated purpose of air-conditioning.

Claims

1. multi-period timing controller of equipment machine room air-conditioning, be made of microcomputer time controlled device, 2 of electronical time relays, distribution box and assembling fittings, it is characterized in that: the multi-period timing controller of equipment machine room air-conditioning forms the dual-delay control circuit by 2 electronical time relay KT1 and KT2.

2. the multi-period timing controller of a kind of equipment machine room air-conditioning according to claim 1 is characterized in that: electronical time relay KT1 control air-conditioning is opened time in the dual-delay control circuit.
