Description

Transducer air conditioning
Technical field
The utility model relates to a kind of transducer air conditioning.
Background technology
The domestic air conditioner common name transducer air conditioning that compressor rotary speed is adjustable, in its automatically controlled control system, characteristics are that its frequency-variable module caloric value is very big, dispel the heat by bigger radiator, otherwise air-conditioner can't be worked.Present transducer air conditioning as shown in Figure 1,11 is that compressor, 12 is the radiator to frequency-variable module cooling for evaporimeter, 15 for restricting element, 14 for condenser, 13.Its radiator 15 is the wind wheel next doors that place off-premises station, and by the rotation of wind wheel, drive radiator ambient air flows and carries out heat exchange.The weak point of this radiator, the one, air is heated through condenser 12, and the 2nd, the distinguished and admirable speed on radiator next door is little, thereby along with the raising of outdoor temperature, the heat-sinking capability of radiator descends.In addition, for the temperature that guarantees frequency-variable module is no more than the safe temperature value, general way is that the compressor operating frequency is reduced, and then reduces the caloric value of module, guarantees the reliability service of air-conditioner.
Disclose a kind of frequency-change air conditioner outdoor machine among the Chinese patent literature CN1904499, it comprises housing, chassis, be arranged on frequency conversion and constant speed compressor and condenser on the chassis, be arranged on the outdoor fan of top, center chassis position; Be arranged on the baffle plate between frequency conversion and constant speed compressor and condenser and the outdoor fan; With the top that is installed in baffle plate, the control box of intelligent transducer module is installed and is arranged on the controller assemblies that the radiator on the control box is formed by inside; Described radiator is made up of rectangular base plate and a plurality of thermal columns of forming from the extension protruding upward of the upper surface of base plate.This complex structure, the radiator cooling-down effect is not obvious.
The utility model content
The purpose of this utility model aim to provide a kind of under hot environment reliability service, guarantee the transducer air conditioning of the comfortableness that the user uses, to overcome weak point of the prior art.
A kind of transducer air conditioning by this purpose design, comprise respectively the condenser and the evaporimeter that join with compressor, and the frequency-variable module of control compressor and the radiator that is used for the frequency-variable module cooling, be connected with restricting element between condenser and the evaporimeter, its architectural feature is to draw a refrigerant transmission pipeline in the condenser, and join by restricting element and radiator, realize taking away the caloric value of frequency-variable module by refrigerant evaporation.
Described refrigerant transmission pipeline one end is communicated with the stage casing or the outlet of condenser, and the other end joins by radiator restricting element and radiator input, and radiator output and compressor join.
Described compressor joins with condenser and evaporimeter respectively by cross valve.Be communicated with by the evaporimeter restricting element between condenser and the evaporimeter.
The utility model after condenser draws one road cold-producing medium throttling to the radiator place, take away the caloric value of module with the evaporation of refrigerant, like this can be than the temperature of the more effective reduction frequency-variable module of air cooling way, guarantee that frequency-variable module is within the normal working temperature, guarantee that compressor also can guarantee the needs of user's refrigeration with higher frequency operation when outdoor temperature is higher.It is simple and reasonable, reliable, the life-span is long.
