Abstract
The utility model relates to the air conditioner energy saving technical field, in particular to a throttling type flash evaporator used by a heat pump air conditioning unit when in heating at the cold area. According to the technical proposal provided by the utility model, a liquid outlet pipe is arranged at the body wall and bottom of a flash tank. A liquid inlet pipe is positioned on and inserted in the body wall of the flash tank, and an inlet end of the liquid inlet pipe is opened upward. The liquid inlet pipe in the flash tank is provided with a saw teeth-shaped flexing capillary pipe, the both ends of which are connected with the liquid inlet pipe. An air outlet pipe is installed on and inserted in the body wall of the flash tank, and an outlet end of the air outlet pipe is opened upward outside the flash tank. By using the utility model, the operation of the heat pump unit under the low temperature environment is more stable and reliable, and the working efficiency is greatly promoted, so that the energy saving function is realized.
Description
Technical field
The utility model relates to the throttle-type flash vessel that the heat pump air conditioner unit of air conditioner energy saving technical field, particularly cold district uses when heating.
Background technology
At present, in the throttle system, throttling arrangement adopts electric expansion valve mostly before flash vessel.After becoming liquid-vapor mixture, a certain pressure enters flash vessel to guarantee to be throttled to from the high pressure refrigerant liquid that condenser comes out.But the price of electric expansion valve is higher, and also restricted to the flow direction of working medium, for this reason, used the throttling arrangement of a capillary in the source pump of prior art as the flash vessel front, can make device structure compacter like this, the simplified apparatus structure reduces equipment cost greatly.But between capillary and flash vessel, still have a segment distance, can cause like this by the cold-producing medium of throttling and in entering the process of flash vessel, be subjected to the influence of environment temperature, and can not arrive expected effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, the throttle-type flash vessel that provide a kind of effective stable and reliable operation that improves compression process, makes unit, operating efficiency improves greatly and the source pump that is applicable to cold district of compact conformation is used.
The technical scheme that provides according to the utility model, be provided with drain pipe in flash tank body wall body bottom, on flash tank body wall body, be provided with the feed tube that inserts in it, the entrance point opening of feed tube is provided with up, on the feed tube that is positioned at flash tank body inside, be provided with one section capillary of indention bending, both ends capillaceous all join with feed tube, are provided with one section escape pipe that inserts in it at flash tank body wall body, and it is external that the port of export opening of escape pipe is arranged on flash tank up.
The port of export opening of feed tube is arranged on flash distillation inner tank wall bottom.The entrance point opening of escape pipe is arranged on flash distillation inner tank wall top down.Feed tube, escape pipe are identical with the drain pipe caliber.Flash distillation tank body two ends are taper, and its middle part is cylindric.Be provided with gathering portion between the conical surface of flash distillation tank body bottom and the drain pipe, this gathering portion upper end is a cylinder, and its lower end is the gathering conical surface that joins with drain pipe.
It is more reliable and more stable that use of the present utility model can make source pump move under low temperature environment, and operating efficiency improves greatly, thereby play energy-conservation effect.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
As shown in the figure: be provided with drain pipe 5 in flash distillation tank body 1 wall body bottom, on flash distillation tank body 1 wall body, be provided with the feed tube 2 that inserts in it, the entrance point opening of feed tube 2 is provided with up, on the feed tube 2 that is positioned at flash tank body 1 inside, be provided with one section capillary 3 of indention bending, the both ends of capillary 3 all join with feed tube 2, be provided with one section escape pipe 4 that inserts in it at flash distillation tank body 1 wall body, the port of export opening of escape pipe 4 is arranged on outside the flash distillation tank body 1 up.
The port of export opening of feed tube 2 is arranged on flash distillation tank body 1 inwall bottom, the entrance point opening of escape pipe 4 is arranged on flash distillation tank body 1 inwall top down, feed tube 2, escape pipe 4 are identical with drain pipe 5 calibers, flash distillation tank body 1 two ends are taper, its middle part is cylindric, be provided with gathering portion 7 between the conical surface 6 of flash distillation tank body 1 bottom and the drain pipe 5, these gathering portion 7 upper ends are cylinder 8, and its lower end is the gathering conical surface 9 that joins with drain pipe 5.
Because the utility model has adopted above-mentioned technical scheme, has increased by one section throttling capillary in flash vessel.When source pump heats, the high pressure refrigerant liquid of coming out from condenser directly enters flash vessel, be throttled to a certain pressure by the capillary in the flash vessel 3 and become liquid-vapor mixture, the direct shwoot of the steam on top, the gas that shwoot is gone out more approaches saturated vapor; Lower liquid is cold excessively owing to the continuous shwoot of steam, and the liquid after mistake is cold is flowed out by the drain pipe 5 of flash vessel.Compare with prior art, the utility model has increased by one section capillary 3 that throttling is used on feed tube 2, can make the high pressure refrigerant liquid that enters in the flash vessel obtain better restriction effect like this, i.e. the gas that flash distillation is gone out more approaches saturated vapor.
The utility model uses heating in the process of source pump, in use, the high pressure refrigerant liquid of coming out from condenser enters flash vessel through feed tube 2, these high pressure refrigerant liquid are throttled to a certain pressure by the capillary on the feed liquor pipeline 3 and become liquid-vapor mixture and flow in the flash distillation tank body 1, the continuous shwoot of steam in the flash distillation tank body 1 is flowed out and auxilairy air intake by compressor is sucked by compressor by escape pipe 4; The liquid of flash tank 1 bottom is cold excessively owing to the continuous shwoot of steam, the liquid of crossing after cold is flowed out by drain pipe 5, subcooled liquid after the outflow enters evaporimeter again after throttling arrangement is throttled to evaporating pressure, the cold-producing medium in the evaporimeter absorbs the heat in the low temperature environment and becomes low-pressure gas and sucked by compressor.And the gathering portion 7 that increases at drain pipe 5 tops, can be so that the liquid after cold excessively flows out flash distillation tank body 1 more easily.
