Description

Freon full-liquid type system flash distillation bucket economizer
Technical field
The invention belongs to refrigeration technology field, be specifically related to freon full-liquid type system flash distillation bucket economizer device.
Background technology
Under high pressure ratio cooling condition, the screw compression with intermediate pressure gas supplementing opening condenses unit, or twin-stage joins dozen compressor bank, generally will run by band charge air cooler. The refrigerating capacity of unit can be improved on the one hand; The deficient compressive state of compressor can be improved on the other hand, improve the COP value of compressor. We are called economizer (ECO) this charge air cooler.
In freon system, most domestic unit manufacturer all adopts plate type heat exchanger to do economizer. This is a kind of economizer cycle once throttled, and economizer has 8-10K heat transfer temperature difference. Its shortcoming is to have heat transfer temperature loss, and economizer expansion valve is often because load variations causes compressor to return liquid beyond its range of accommodation greatly, increases the risk of compressor abrasion, causes that compressor is short for service life.
Summary of the invention
The invention aims to improve the service life of compressor, improve the Energy Efficiency Ratio of refrigeration system.
Technical scheme: freon full-liquid type system flash distillation bucket economizer device, is characterized in that including flash distillation bucket, choke valve, liquid supply electromagnetic valve, QI invigorating electromagnetic valve, check valve, a second throttle valve; Flash distillation bucket is connected with high-pressure reservoir by a choke valve and liquid supply electromagnetic valve, and flash distillation bucket is connected with low pressure recycle bucket by second throttle valve; Flash distillation bucket is connected with compressor by QI invigorating electromagnetic valve and check valve, and high-pressure reservoir is connected with condenser, and condenser is connected with compressor; Compressor connects low pressure recycle bucket, and the import of low pressure recycle bucket connects vaporizer, and the outlet of low pressure recycle bucket connects vaporizer by check valve.
Arranging liquid level controller in described flash distillation bucket, liquid level controller connects liquid supply electromagnetic valve.
The operation principle of freon full-liquid type system flash distillation bucket economizer device: condensed refrigerant liquid enters high-pressure reservoir, and to become pressure be that 11 ~ 18bar(depends on cold-producing medium and condensation temperature) high-pressure refrigerant, the first time throttling entrance flash distillation bucket that passes through of high-pressure refrigerant becomes middle compression refrigerant, the force value of middle compression refrigerant (1.3～5.8bar identical with the force value at the middle pressure gas supplementing opening place of compressor, depend on cold-producing medium and evaporating temperature), cold-producing medium gasifies a part of (the more low ratio of 20%～38% evaporating temperature is more big) in the process of blood pressure lowering, remaining refrigerant liquid obtains cooling, the gas of flash distillation bucket shwoot is therefrom pressed gas supplementing opening to siphon away by compressor,Remaining refrigerant liquid is not because have heat transfer temperature loss, and its degree of supercooling becomes more greatly supercool saturated liquid (be supercool relative to condensation temperature, but because throttle and be saturated liquid), and supercool saturated liquid enters low pressure recycle bucket through second throttle.
The economizer device of the present invention can obtain bigger degree of supercooling thus improve the Energy Efficiency Ratio of refrigeration system, can prevent compressor from returning the risk of liquid simultaneously.
Flash distillation bucket of the present invention does not have heat transfer temperature loss, and Energy Efficiency Ratio is higher.
Have compared with the economizer of 8-10K heat transfer temperature difference with plate type heat exchanger, the present invention can obtain the liquid of more big supercooling degree and improve 5-6% to vaporizer feed flow, refrigerating capacity and Energy Efficiency Ratio.
Flash distillation bucket of the present invention, with liquid level controller, can guarantee that and presses gas supplementing opening not return liquid in compressor, and compressor operating is safer.

Detailed description of the invention
Freon full-liquid type system flash distillation bucket economizer device, is characterized in that being made up of flash distillation bucket, choke valve, liquid supply electromagnetic valve, liquid level controller, QI invigorating electromagnetic valve, check valve, a second throttle valve; Flash distillation bucket is connected with high-pressure reservoir by a choke valve and liquid supply electromagnetic valve, and flash distillation bucket is connected with low pressure recycle bucket by second throttle valve; Flash distillation bucket is connected with compressor by QI invigorating electromagnetic valve and check valve, and high-pressure reservoir is connected with condenser, and condenser is connected with compressor; Compressor connects low pressure recycle bucket, and the import of low pressure recycle bucket connects vaporizer, and the outlet of low pressure recycle bucket connects vaporizer by check valve. Arranging liquid level controller in described flash distillation bucket, liquid level controller connects liquid supply electromagnetic valve.
Condensed refrigerant liquid enters high-pressure reservoir, and to become pressure be that 11 ~ 18bar(depends on cold-producing medium and condensation temperature) high-pressure refrigerant, the first time throttling entrance flash distillation bucket that passes through of high-pressure refrigerant becomes middle compression refrigerant, the force value of middle compression refrigerant (1.3～5.8bar identical with the force value at the middle pressure gas supplementing opening place of compressor, depend on cold-producing medium and evaporating temperature), cold-producing medium gasifies in the process of blood pressure loweringA part(the more low ratio of 20%～38% evaporating temperature is more big), remaining refrigerant liquid obtains cooling, and the gas of flash distillation bucket shwoot cools remaining refrigerant liquid in bucket therefrom being pressed gas supplementing opening by compressor while siphoning away; Remaining refrigerant liquid is not because having heat transfer temperature loss, and its degree of supercooling becomes more greatly supercool saturated liquid, and supercool saturated liquid enters low pressure recycle bucket through second throttle.
Liquid level in flash distillation bucket is controlled liquid supply electromagnetic valve 3 by liquid level controller 4, it is ensured that liquid level can not be too high. QI invigorating electromagnetic valve 5 machine by compression controls, and compressor is opened and reached economizer device and puts into condition, and QI invigorating electromagnetic valve 5 is opened, and during compressor shutdown, QI invigorating electromagnetic valve 5 cuts out.
