Description

Multi-stage condensing refrigerating plant
Technical field
The utility model relates to refrigeration plant, particularly relates to a kind of multi-stage condensing refrigerating plant carrying out cold recovery.
Background technology
The refrigeration plant of prior art is generally take air-cooled technology or Water Cooling Technology.Wherein air-cooled technology is generally in family or small size environmental applications, this air-cooled condensing refrigerant device, and as shown in Figure 1, compressor, condenser, flow controller, evaporimeter 4 essential parts circulate connection its structure successively, and form refrigerating circuit.Suck the low pressure refrigerant gas of flash-pot when compressor start, be compressed into the cold-producing medium of HTHP, then flow through condenser successively, flow controller forms low-temperature low-pressure refrigerant, evaporate in evaporimeter and absorb from indoor atmospheric heat.This pure air-cooled condensing refrigerant device is one-level condensation, and shortcoming is that radiating effect is poor, energy consumption is high, refrigerating efficiency is low.
Prior art another be water cooling equipment, it is generally applied in industry or commercialization.Water-cooled condensing refrigerant device, its structure to be circulated connection successively by compressor, water-cooled condenser, flow controller, evaporimeter 4 essential parts equally, forms refrigerating circuit; Compared with air-cooled condensing refrigerant device, its structure increases cooling tower, water circulating pump, and accesses the circulating water loop of water-cooled condenser formation.The low pressure refrigerant gas sucking flash-pot when compressor start is compressed into the cold-producing medium of HTHP, then flows through water-cooled condensation, and throttling becomes low-temperature low-pressure refrigerant, evaporates the atmospheric heat in absorption chamber in evaporimeter.This water-cooled refrigeration structure is one-level condensation, and shortcoming is that radiating effect is poor, power and water energy consumption is higher, refrigerating efficiency is low equally.
Summary of the invention
The utility model object is to provide that a kind of good heat dissipation effect, power and water energy consumption are low, refrigerating efficiency much higher level condensing refrigerant device.
The utility model multi-stage condensing refrigerating plant, its structure is interconnected is formed by compressor, condenser, flow controller, evaporimeter, it is characterized in that: accessed cold recovery heat exchanger between condenser and flow controller, this is crossed cold recovery heat exchanger and accesses between evaporimeter and compressor simultaneously in addition.
The cold recovery heat exchanger of described mistake is double-layer sleeve structure, is positioned at the pipe of central authorities, and its input connects evaporimeter, and output connects the air entry of compressor; Be positioned at the outer tube of perisporium, its input connects water-cooled condenser, and output connects flow controller.
As crossing the application of cold recovery heat exchanger at air-cooled condensing refrigerant device, described condenser is air-cooled condenser.
As crossing the application of cold recovery heat exchanger at water-cooled condensing refrigerant device, described condenser is water-cooled condenser, and in water-cooled condenser, pipe connects water circulating pump, storage tank simultaneously, and forms circulating water loop.
For improving the refrigerating efficiency of large area environment further, described condenser is two, is water-cooled condenser and air-cooled condenser respectively, and mutually connects, and in water-cooled condenser, pipe connects water circulating pump, storage tank simultaneously, and forms circulating water loop.
Multi-stage condensing refrigerating plant of the present utility model, suck when compressor start the low pressure refrigerant gas of flash-pot be compressed into HTHP cold-producing medium, then flow through air-cooled condenser, water-cooled condenser, cross cold recovery heat exchanger, flow controller throttling becomes low-temperature low-pressure refrigerant in evaporimeter, evaporate atmospheric heat in absorption chamber, this refrigeration structure comprises the multi-stage condensing structure that air-cooled water-cooled crosses cold recovery form, has good heat dissipation effect, power and water energy consumption is little, refrigerating efficiency is high advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation of the air-cooled condensing refrigerant device of prior art;
Fig. 2 is the structural representation of the utility model multi-stage condensing refrigerating plant;
Fig. 3 is the structure sectional view that the utility model crosses cold recovery heat exchanger.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model multi-stage condensing refrigerating plant is described further.
Referring to Fig. 2, Fig. 3, multi-stage condensing refrigerating plant of the present utility model, its structure comprises storage tank, water circulating pump, connecting water pipe, water filter, shower with holes, the wet curtain of cooling and water-cooled condenser and is interconnected, and forms circulating water loop, is represented by dotted lines; Simultaneously cold recovery heat exchanger crossed by air-cooled condenser, water-cooled condenser, cold-producing medium, flow controller, evaporimeter, compressor connect to form refrigerating circuit successively, represents with solid line.The cold recovery heat exchanger of described mistake is double-layer sleeve structure, is positioned at the pipe 1 of central authorities, and its input connects evaporimeter, and output connects the air entry of compressor; Be positioned at the outer tube 2 of perisporium, its input connects water-cooled condenser, and output connects flow controller.
Compressor will suck the low pressure refrigerant of flash-pot, be compressed into the flow of refrigerant of HTHP through air-cooled condenser and water-cooled condenser, after cooling, cold-producing medium is through cold recovery heat exchanger, flow controller, throttling becomes the cold-producing medium of low-temp low-pressure, absorb in evaporimeter from room air heat, become low pressure refrigerant; The remaining cold of low pressure refrigerant, then transmission has been cold recovery heat exchanger, reverse cooling water cool condenser cold-producing medium out; Low pressure refrigerant is sucked by compressor simultaneously, so compresses, and------throttling---is crossed cold recovery---and is evaporated iterative cycles, forms high efficiency energy saving refrigeration loop in condensation.System starts water circulating pump, and water is evenly sprayed water to cooling wet curtain upper portion by pipe, water filter, shower with holes in connecting water pipe, water-cooled condenser, starts condensation fan simultaneously.Install the wet curtain of cooling inside air-cooled condenser, condensation fan is installed in outside.When condensation fan starts, the flow direction of air is that heated dry air becomes clammy air through cooling wet curtain, then becomes damp-heat air through air-cooled condenser, outside discharge machine.Due to water spray equably moistening whole cooling to wet the contact surface of curtain, form moisture film, make wet curtain moisture film rapid evaporation by condensation fan and take away air amount of heat; And after cold wind carries out heat exchange cooling by air-cooled condenser and cold-producing medium, again cross cold recovery heat exchanger by cold-producing medium through water-cooled condenser, the condensation temperature reducing cold-producing medium further absorbs from room air heat in evaporimeter; Room air, after evaporator, releases heat, and air themperature declines.Iterative cycles like this, the heat of room air constantly taken away by cold-producing medium, thus reduces indoor temperature, improves air conditioner refrigerating efficiency and reaches energy-saving environmental-protection function.
The air-cooled water-cooled of above-mentioned refrigerating plant set crosses the condensing refrigerant form of cold recovery, belongs to three grades of condensing refrigerant devices.In addition according to the needs of environment for use, can air-cooled condenser be removed, form the B-grade condensation refrigerating plant that water-cooled crosses cold recovery; Similarly, remove water-cooled condenser and whole circulating water loop, form the B-grade condensation refrigerating plant of the cold recovery of air-cooled mistake, but effect does not have three grades of condensing refrigerant device good energy-conserving effects.
