Abstract
The utility model discloses a combined throttling device which is arranged between a condenser and an evaporator and is communicated with the condenser, the evaporator and a compressor by a communicating pipeline. The combined throttling device is composed of an orifice plate and an electronic expansion valve which are arranged in parallel, and the related compressor, the condenser, the orifice plate and the electronic expansion valve arranged in parallel, the evaporator and the compressor are communicated in sequence to form a loop through the pipeline, and are also electrically connected with a central controller and accept the instructions of the central controller, namely, the orifice plate accepts the instructions of the central controller when operating under rated load so as to supply liquid to the evaporator, and the electronic expansion valve accepts the instructions of the central controller when in operation so as to supply liquid with the orifice plate to the evaporator. Compared with the prior art, no matter under any working conditions and loads, the combined throttling device has ideal control accuracy, high energy efficiency ratio, broad regulating range of liquid feeding amount, quick response speed, convenient parameter setup and flexible regulation, thus not only expanding the range of working condition but also having no risk of liquid compressing.
Description
Technical field
The utility model relates to a kind of central air-conditioning full-liquid type handpiece Water Chilling Units, is meant a kind of full-liquid type handpiece Water Chilling Units combined type throttling arrangement especially.
Background technology
Along with China's rapid economy development, energy availability and demand contradiction is more and more outstanding, and the pressure that environment bore is also more and more heavier, and the full-liquid type handpiece Water Chilling Units of high energy efficiency ratio is arisen at the historic moment thereupon and popularized on market gradually.Throttling arrangement is one of indispensable parts of refrigeration plant, and full-liquid type handpiece Water Chilling Units throttling arrangement commonly used roughly has orifice plates, electric expansion valve and float valve etc. at present.Though orifice plates and float valve cost are low, control accuracy is also low, and electric expansion valve is just in time opposite, the control accuracy height, but cost is also high.No. 03116026.3 utility application of China " throttle mechanism of heating power expansion valve and capillary paralleling " has disclosed a kind of design that is used for domestic air conditioning heating power expansion valve, magnetic valve and three kinds of throttling devices of capillary and usefulness.Wherein, heating power expansion valve is installed in the evaporator refrigerant inlet pipeline as main restricting element; Capillary is as assistant throttle component, and is in parallel with heating power expansion valve.Magnetic valve is equipped with in import department at capillary, controls switching capillaceous by the open and close of control magnetic valve.When closed electromagnetic valve, no cold-producing medium flows through in the capillary, and heating power expansion valve is independent of the cold-producing medium throttling.When magnetic valve was opened, to the cold-producing medium throttling, the cold-producing medium handling capacity was strengthened behind heating power expansion valve and the capillary paralleling, and refrigerating capacity increases.This throttle mechanism has been widened the operating mode scope of refrigeration, air-conditioning equipment to a certain extent.
The utility model content
At having the deficiency that full-liquid type handpiece Water Chilling Units throttling arrangement exists in the market now, the utility model provides a kind of orifice plates and the knockdown throttling arrangement of electric expansion valve, so that system configuration cost and control accuracy are more reasonable.
Designed a kind of combined type throttling arrangement according to the above-mentioned problem that needs to solve, be installed between condenser and the evaporimeter, and pass through pipeline connection with condenser and evaporimeter, condenser and evaporimeter are communicated with compressor respectively by pipeline, described combined type throttling arrangement is made up of orifice plates parallel with one another and electric expansion valve, and the two ends pipeline after this orifice plates and electric expansion valve are connected in parallel by pipeline is communicated with condenser and evaporimeter respectively.Compressor wherein, condenser, orifice plates parallel with one another and electric expansion valve, evaporimeter, compressor are communicated with in regular turn by pipeline and form loop, also all be electrically connected and accept the instruction of central controller with central controller, be described orifice plates when underrun, accept central controller instruction to the evaporimeter feed flow, described electric expansion valve is accepted the instruction of central controller to the evaporimeter feed flow when heavy-duty service.
Compared with prior art, no matter the utility model is under which kind of operating mode and the load, have all that ideal control precision and Energy Efficiency Ratio height, liquid supply rate adjustable range broadness, response speed are fast, parameter is provided with conveniently, regulates flexibly, promptly widened also aneroid compression risk of operating mode scope.
Description of drawings
Accompanying drawing 1 is installation and the connected mode schematic diagram of the utility model in aircondition.Number in the figure is compressor 1, condenser 2, orifice plates 3, electric expansion valve 4, evaporimeter 5.
The specific embodiment
Purport of the present utility model provides a kind of actual motion load according to unit, the combined type choke valve of the duty of reasonable adjustment hole oralia and electric expansion valve, that is: when unit operation during at underload only by orifice plates to the evaporimeter feed flow, when unit load exceeds the capacity of orifice plates, by orifice plates and electric expansion valve simultaneously to the evaporimeter feed flow.The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model in the refrigeration pipe of full-liquid type handpiece Water Chilling Units central air-conditioning installation and connected mode as shown in drawings, compressor 1, condenser 2, orifice plates 3 parallel with one another and electric expansion valve 4, evaporimeter 5, compression 1 machine are communicated with in regular turn by pipeline and form loop, and they are and all be electrically connected and accept the instruction of central controller with central controller.Wherein, the throttling arrangement working method is, the duty that central controller comes adjustment hole oralia and electric expansion valve according to the actual motion load of full-liquid type handpiece Water Chilling Units, promptly orifice plates when underrun, accept central controller instruction to the evaporimeter feed flow, at this moment electric expansion valve is closed; Electric expansion valve is accepted central controller when heavy-duty service instruction with orifice plates to the evaporimeter feed flow.Design main points of the present utility model are that single throttling device is changed into by two kinds of performance differences, the coexistence in parallel of the different throttling device of adaptive surface, have expanded the operating mode scope of full-liquid type handpiece Water Chilling Units complete machine.In addition, the utility model can naturally and understandably extend from the handpiece Water Chilling Units and the central air-conditioning of full-liquid type handpiece Water Chilling Units to other type, there is no the design obstacle technically.
