Abstract

A series of non-azeotropic mixed refrigerants containing two or more components for thermal circulation system features that it is suitable for 4 working temp ranges of refrigeration, air conditioner, heat pump and electric generation by hot fluid, existing apparatus is reformed only a little or even not, and energy is saved by 15-30%.

Description

The improved non-azeotropic operating medium that in thermodynamic cycle, uses
This invention relates to the relevant working medium of circulation system, particularly, it relates to the non-azeotropic of a class, useful mixture, for example, in contrary circulation device, there is higher coefficient of performance COP[COP to be defined as or exports the ratio of specific energy (with regard to heating) and total input energy only from clean exhaust energy rate (with regard to regard to the refrigeration) the surrounding environment, be expressed as a constant unit and Ratio Conditions], in the normal circulation device, higher mechanical efficiency is arranged.
At present on commercial and industrial, the working medium that is used for circulation system is some pure components normally, or azeotropic and non-azeotropic working medium.
Many such mixtures are made public, and for example, following reference: 1. United States Patent (USP) 2,641,580, are entitled as " 1, the composition of a 1-Tetrafluoroethane and a chloropentafluoroethane azeotrope refrigerant ", contriver: Lewis, patent approval day: June 9 nineteen fifty-three.2.

Japanese Patent 52-70466 is entitled as " composition of low boiling point refrigerant ", and contriver: Kokai was published in DaKogyo KK in 1977.6.

French Patent 2,177,785 (VEB MonsatorHaushait grossgeratekombinat).9. French Patent 2,607,144 (Institute Francaise du Petrole).10. " chloro-fluorocarbon and surrogate thereof ", author: M.F.Bouzianis (ArthurD.Little, 1988).The frigorific mixture 11. of used for automobile air conditioning " after market ", author: D.J.Bateman etc., SAE series technique paper 900216 (SAE international conference and exhibition one Detroit, Michigan, 26 days～March 2 February nineteen ninety." 12. ASHRAE heat supply, ventilation, air-conditioning and refrigeration glossary ", second edition (U.S.'s heat supply, refrigeration and air-conditioning man SCTE, 1991).
Under basic identical circulation external conditions, compare with a pure working medium or an azeotropic working medium, zeotrope (if outstanding) is a kind of so advantageous working medium, its advantage is, in isobaric evaporative process, inhale more heat, in isobaric condensation process, put more heat, in expansion process, do more merit or in compression process, do still less merit, that is to say, in contrary circulation device, higher coefficient of performance COP is arranged, in the normal circulation device, higher mechanical efficiency is arranged.
But each refrigeration agent all has certain limitation, for different vaporization temperature zone and condensing temperature zones, can not there be a kind of mix refrigerant to be suitable for simultaneously, therefore must seek more kinds of refrigeration agents, in addition, be used in refrigeration and the conditioning unit at these refrigeration agents of formerly being introduced in the patent, energy-saving effect is all not very big, is generally 5%-10%.In addition, these refrigeration agents formerly often require former refrigeration and conditioning unit are done transformation than many places, and this will bring difficulty to practical application and popularization.
The invention provides a series of non-azeotropic operating mediums that contain the circulation system of two or more component, its feature is, the energy-saving effect that larger proportion can be arranged, be applicable to refrigeration, air-conditioning, heat pump, four kinds of working temperature zones of hot fluid generator simultaneously, and need only carry out less change or not do the mixed non-azeotropic refrigerant of change refrigeration, air-conditioning, heat pump, thermal fluid power device in actual applications.This refrigeration agent can save energy 15-25% in air-conditioning plant, can save energy 15-30% in refrigeration plant, can save energy 15-30% in thermal-pump unit, can improve capacity usage ratio more than 20% in thermal fluid power device.
Fig. 1 has represented a kind of refrigeration unit that uses non-azeotropic operating medium of the present invention.
Fig. 2 has represented the description of device of the main assembly of air-conditioning plant of the sort of refrigeration unit manufacturing of a kind of Fig. 1 of use.
Referring to the shown refrigeration unit of Fig. 1, working medium among the present invention circulates in a following recycle system, the direction of the arrow indication at 15 places among round-robin direction such as the figure, fluid flows to condenser 30 by compressor 20 by the sensing at 15 places, is throttling valve 40 then, is vaporizer 50 then, flow back to compressor 20 then, condenser 30 links to each other with an interchanger, and passes through this interchanger heat transferred another one device, such as cooling column 60.Vaporizer 50 is to a specified control space cooling, with remove this spatial heat or it by a heat exchanger to a cryogen 70 supply colds.
Referring to Fig. 2, an air-conditioning system according to present invention manufacturing, comprise a refrigeration unit 140 (being presented among Fig. 1) and a fluid flow line 100, this streamline representative provides fresh air, the control loop 105 that comprises a recirculation, the air that air that is provided by 105 loops and 110 lines provide mixes in mixing tank 120, through fan in 130 and strainer, then to being similar to a refrigeration plant 140 shown in Figure 1, and then, lead to a part flow arrangement 170,180 then to humidifier 150.170,180 splitting systems are all supplied freezing air user 190 respectively respectively.
Working medium of the present invention can be used in compression, condensation, expansion and the evaporation circulating system on the thermal engineering, as the power generation assembly of thermal-pump unit, refrigeration plant, air-conditioning plant and hot-fluid, and does not need these systems to do expensive modification.
The impurity of being mentioned is meant any material except that the specified ingredients material and composition thereof in the present invention.
