Abstract
The utility model is applicable to the field of central air conditioners and energy conservation, and provides an energy-conserving system of a central air conditioner and the central air conditioner. The system comprises a unit, control equipment and an electric valve, wherein the electric valve is connected with the control equipment, positioned at a water outlet of the unit and synchronous with the working state of the corresponding unit. By adopting the technical scheme, the utility model has the advantage of low energy consumption.
Description
Technical field
The utility model belongs to central air-conditioning and energy field, relates in particular to a kind of energy conserving system and central air-conditioning of central air-conditioning.
Background technology
Development along with urbanization process, central air-conditioning is more and more in the heavy construction, the energy consumption of central air-conditioning is more than 40% of whole building at present, and the central air-conditioning unit is to design with the maximum cold heat that satisfies practical place, and the design margin of 10%-20% is generally all arranged.The energy conserving system of present central air-conditioning is to control unit work by the controller of the automatic control system of building or central air-conditioning, generally speaking, the unit of central air-conditioning (being generally more than 3 or 3) can not worked simultaneously, so work unit and total unit number have difference, the water inlet and the delivery port of unit all do not have valve at present, cause unit discharge need enter all units (comprising work unit and inoperative unit), cause work unit discharge to reduce, pressure reduces, and causes energy consumption to increase.
The utility model content
The purpose of this utility model is to provide a kind of central air-conditioning energy-saving system, is intended to solve the problem that the unit water inlet of central air-conditioning of the prior art and energy consumption that delivery port does not have valve to cause increase.
The utility model is achieved in that a kind of energy conserving system of central air-conditioning, and described system comprises:
Unit, control appliance and electrically operated valve; Wherein electrically operated valve is connected with control appliance, and it is synchronous that described electrically operated valve is positioned at the duty of the delivery port of unit and unit pairing with it.
The utility model also provides a kind of central air-conditioning, and described central air-conditioning comprises the energy conserving system of above-mentioned central air-conditioning.
The utility model compared with prior art, beneficial effect is: by the delivery port at unit electrically operated valve is installed, and electrically operated valve is also synchronous with the duty of unit, so when unit was the inoperative unit, electrically operated valve was closed, all current are not from this inoperative unit circulation, like this under the constant situation of the total amount of water, reduce the branch road of current, the discharge and the hydraulic pressure of sure increase work unit, thus reach energy-conservation effect.
Description of drawings
Fig. 1 is the structure chart of the energy conserving system of a kind of central air-conditioning of providing of the utility model embodiment.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model provides a kind of energy conserving system of central air-conditioning, and this system comprises as shown in Figure 1: unit 11, control appliance 12 and electrically operated valve 13; Wherein electrically operated valve 13 is connected with control appliance 12, and is positioned at the delivery port of unit 11.Need to prove that this delivery port comprises: cooling water and/or chilled water delivery port.
Wherein, unit 11 can be for a plurality of, and this unit 11 is specifically as follows: cold water group machine or frozen water group machine.
Optionally, electrically operated valve 13 can also be positioned at the water inlet of unit 11, and this water inlet comprises: cooling water and/or chilled water water inlet.
Optionally, electrically operated valve 13 is positioned at the delivery port of all units 11, also can be positioned at the delivery port of setting unit, wherein sets the unit user and can select 1,2 or a plurality of unit in all units according to self needs.Certainly in actual conditions, also all units all can be installed electrically operated valve 13.
Optionally, the duty of the unit 11 that electrically operated valve 13 is corresponding with electrically operated valve is synchronous, and promptly unit 1 is in running order, and then electrically operated valve 13 is in normally open, and unit 11 is in off working state, and electrically operated valve 13 is in normally off.The unit 11 of electrically operated valve correspondence is specifically as follows, and the unit of the delivery port correspondence of electrically operated valve control is installed in the delivery port of first unit as electrically operated valve, and then the unit of this electrically operated valve correspondence is first unit.
Above-mentioned control appliance 12 specifically can comprise: building automatic control system, central air-conditioning automatic control system or unit control appliance.
Operation principle below by above-mentioned energy conserving system illustrates the effect that the utility model reaches, owing to electrically operated valve is installed at unit, and electrically operated valve is also synchronous with the duty of unit, so when unit is the inoperative unit, electrically operated valve is closed, all current are not from this inoperative unit circulation, like this under the constant situation of the total amount (total flow and gross pressure) of water (cooling water or chilled water), reduce the branch road of current, the discharge and the hydraulic pressure of sure increase work unit, thus reach purpose of energy saving.
The utility model also provides a kind of central air-conditioning, and this central air-conditioning comprises above-mentioned central air conditioning system.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
