Description
Technical field
The present invention relates to a kind of flash vessel for compressor, relate to a kind of flash vessel that the cooling oil circuit of compressor is used for the heating internal capacity particularly.The invention still further relates to a kind of cooling system that comprises this flash vessel.
Background technology
At the compressor that is used for cooling system, can use vapor injection system to improve refrigerating efficiency by supplying middle pressure steam to compressor to compressor.Because middle pressure steam is higher slightly and brake specific exhaust emission pressure is low slightly than suction pressure, has therefore reduced compressor and produced the required merit of steam that is in blowdown presssure.
Vapor injection system is extracted middle pressure steam out from flash vessel usually, be used for it is ejected into the discharge chambe of compressor, flash vessel is usually with compressor and a pair ofly link to each other for the heat exchanger that improves power system capacity and efficient, and this heat exchanging device is used separately as condenser and evaporimeter according to heating mode or refrigerating mode.
Be in operation, flash vessel receives liquid refrigerant from condenser, is used for being transformed into middle pressure steam and sub-cooled liquid refrigerant.Because flash vessel remains under the pressure lower for the entrance liquid refrigerant, thus some liquid refrigerant evaporates, thus the pressure of the gasified refrigerant in the raising flash vessel.Remaining liquid refrigerant heat release and became cold in the flash vessel is to be used for evaporimeter.Therefore, conventional flash vessel had both contained gasified refrigerant, also contained cold liquid refrigerant.
Be assigned to the middle pressure input port of compressor from the gasified refrigerant of flash vessel, thus, gasified refrigerant is in the pressure that is higher than the gasified refrigerant of leaving evaporimeter substantially but is lower than the liquid refrigerant that leaves compressor.Pressurize refrigerant from flash vessel makes compressor the cold-producing medium of pressurization only namely can be compressible to normal output pressure through after the part of compressor.
Subcooled liquid is discharged from flash vessel and is transported in the heat exchanger one according to heating mode or the refrigerating mode of expectation.Because aforesaid liquid is in supercooled state, thus can absorb more heat from surrounding environment by heat exchanger, thus improve overall heating or the cooling performance of system.
To mobile regulate of pressurize refrigerant from flash vessel to compressor, to guarantee only have the cold-producing medium of vaporization or minimum liquid to enter in the compressor.Equally, to mobile regulate of sub-cooled liquid refrigerant from flash vessel to heat exchanger, flow to evaporimeter to stop gasified refrigerant from flash vessel.Conventional flash vessel is its porch regulator solution cryogen flowing in the flash vessel, be fed in refrigerating mode and/or heating mode process with control compressor gasified refrigerant amount and be fed to the amount of the sub-cooled liquid refrigerant of evaporimeter.
Generally, need be equipped with the cooling oil circuit for compressor, in order to the heat generating components of compressor is cooled off, and for movable part provides lubrication, thereby the assurance compressor can be worked long-term and stably.In addition, in order to guarantee to cool off the normal operation of oil circuit, also need for the cooling oil circuit arranges heat exchanger, thereby reduce the temperature of cooling machine oil, to guarantee cooling and the lubricating function of cooling machine oil.Therefore, the compressor that is used for cooling system in the prior art need arrange himself flash vessel and heat exchanger for compressor, and it is complicated that this causes the pipeline of refrigeration system to connect, and cause its reliability to reduce.
In addition, in order to improve the flash distillation effect of flash vessel, prevent the flash distillation deficiency under the low temperature environment for use, need heater be set for flash vessel.This not only makes the structure of flash vessel become complicated, and has consumed big energy.
The objective of the invention is to propose a kind of new-type flash vessel, thereby overcome the above-mentioned problems in the prior art.
Summary of the invention
