Abstract
The utility model relates to an outdoor variable frequency condenser unit, which comprises a variable frequency compressor, an oil separator, a gas-liquid separator, an electric control cabinet, a condenser fan, a condenser, a liquid storage tank, a frequency converter, a liquid sight glass and a gas absorbing angle valve. When in work, the condenser unit requires an external evaporator (a freezer or an air cooler), low-temperature low-pressure gas from the evaporator enters the gas-liquid separator, the gas is subjected to gas-liquid separation in the gas-liquid separator before entering the variable frequency compressor for compression, the compressed high-temperature high-pressure gas enters the oil separator to be subjected to oil-gas separation in the oil separator, separated oil returns into a suction pipe of the compressor, separated high-temperature high-pressure gas enters the condenser, the high-temperature high-pressure gas is cooled in the condenser into high-pressure undercooled liquid entering the liquid storage tank, lastly the liquid returns to the evaporator (the evaporator is provided with an expansion valve for throttling), and gas-liquid mixed refrigerant in the evaporator absorbs heat to continue generating low-temperature low-pressure gas to realize the whole cycle. The variable frequency condenser unit can be subjected to variable frequency control according to change of cooling load so as to reduce work load fluctuation of the compressor and to reduce starting and stopping times of the compressor, thereby the condenser unit has the advantages of noise reduction at night, energy conservation and stableness, and further, the outdoor design leads the condenser unit to have the advantages of space economization and convenience in installation.
Description
Technical field the utility model relates to the condensation unit of outdoor version, and the utility model is the outdoor version frequency conversion condensation unit that frequency converter is arranged.
Background technology is along with the development of refrigeration industry and the people improve to requirements of saving energy.Make frequency conversion and refrigeration compressor being used in combination in refrigeration system, becoming the research institution of main flow and the research topic of manufacturer in the world now.Wherein the supermarket refrigeration system is one of the most suitable field of frequency conversion.In the compressor bank that is having in the market with frequency converter, but this unit is only applicable to indoor service condition, installs restrictedly, uses inconvenient; Simultaneously have outdoor condensation unit, but the unit of outdoor version do not have frequency converter, has just lacked frequency conversion unit energy-saving advantages yet yet.Along with the development in market, in conjunction with both characteristics, our novel practical patent room external form frequency conversion condensation unit arises at the historic moment.
Summary of the invention
Goal of the invention: be for market provides a energy-conservation, stable, outdoor version frequency conversion condensation unit easy for installation
Technical scheme: the utility model is an outdoor version frequency conversion condensation unit, and it comprises frequency-changeable compressor, oil eliminator, vapour liquid separator, electric cabinet, condenser fan, condenser, fluid reservoir, frequency converter, liquid-sighting glass, air-breathing angle valve, feed flow angle valve.
By frequency-changeable compressor cold-producing medium is compressed, the gas that is compressed into HTHP enters oil eliminator, in oil eliminator, realize separating of oil and gas, isolated oil is got back in the compressor suction duct, isolated high temperature and high pressure gas enters condenser, in condenser, make high-temperature gas be cooled to the cold excessively liquid of high pressure and enter fluid reservoir, enter the feed flow angle valve by fluid reservoir through liquid-sighting glass, provide cold by the feed flow angle valve to external equipment, by external equipment come out for the gas of low-temp low-pressure, low-temp low-pressure gas enters air-breathing angle valve, and air-breathing angle valve is opened and made the gas of low-temp low-pressure enter vapour liquid separator, realizes gas-liquid separation in vapour liquid separator, prevent that effectively compressor from returning liquid, reduce the infringement of compressor, the refrigerant gas after separating enters frequency-changeable compressor, thereby realizes whole kind of refrigeration cycle.In whole kind of refrigeration cycle process, come frequency-changeable compressor is carried out the control of frequency conversion rate according to the thermic load of external equipment by frequency converter.
The utility model advantage: the frequency-changeable compressor group, can carry out VFC according to the variation of cooling load, the live load fluctuation of compressor is reduced, reduce the startup-shutdown number of times of compressor, the noise that makes unit have night reduces energy-conservation stable advantage; Electric cabinet and frequency converter used in the frequency-changeable compressor group are automatically controlled, and compressor electronic control has all adopted waterproofing design, can adapt to outdoor environment for use, make this unit have conserve space, and convenient advantage of installing is having very strong practicality and versatility.

The specific embodiment
As shown in the figure, outdoor version frequency conversion condensation unit of the present utility model comprises: its chief component has frequency-changeable compressor 1, oil eliminator 2, vapour liquid separator 3, electric cabinet 4, condenser fan 5, condenser 6, fluid reservoir 7, frequency converter 8, liquid-sighting glass 9, air-breathing angle valve 10, feed flow angle valve 11.Reality when using is installed on this unit outdoor, indoor connection evaporator device (reach in freezer or air-cooler etc.), and this unit provides cold to evaporator device, realizes the refrigerating process of article in the evaporator device.
Described frequency-changeable compressor is semiclosed frequency-changeable compressor, and the motor and the moving component of special configuration adopted in frequency conversion compression, can adapt to the compressor operating frequency and change within the specific limits and can not cause damage to compressor.Described condenser, two quarter bends have been rolled over, become the U type, this structure has been saved usage space under same cooling capacity, make compacter that the overall structure of unit can do, the copper pipe of condenser adopts riffled tube, and fin adopts the skylight chip architecture with Sanyo's patent, these structures have improved the exchange capability of heat of condenser, are a efficient condensers.Described fluid reservoir has adopted and has gone out structure under enterprising, helps flowing of cold-producing medium.
As shown in Figure 1, during the work of this outdoor version frequency conversion condensation unit, suck refrigerant gas by air-breathing angle valve and enter vapour liquid separator (avoiding compressor to return liquid), refrigerant gas enters frequency-changeable compressor (reconciling the frequency of compressor operating), the gas that frequency-changeable compressor is discharged HTHP enters oil eliminator, oil eliminator separates oil with gas, isolated high temperature and high pressure gas enters condenser, condenser forms the cold excessively liquid of high pressure with the gas cooling, enter fluid reservoir, the liquid refrigerant of the fluid reservoir liquid-sighting glass (can observe what and quality of cold-producing medium) of flowing through enters the feed flow angle valve, giving external equipment (can be reach in freezer, air-cooler etc.) by feed flow cools.
