Description
Technical field
The invention provides a kind of novel refrigerating machine being working medium with the cold-producing medium such as ammonia or chloromethanes.This novel refrigerating machine is except comprising the conventional components such as compressor, condenser, choke valve and evaporimeter, and also comprise the critical pieces such as multiple-way valve, generator and conventional heat engine, the structure of novel refrigerating machine condenser is different with the structure of general refrigerator condenser.This novel refrigerating machine can absorb heat by its thermodynamic process and utilize external atmospheric pressure to do work from freezer, therefore can save electric energy.
Background technology
We know, conventional chiller is power consumption very, and external atmospheric pressure can not be utilized to do work, and the whole world is faced with the day by day exhausted problem of global warming, fossil fuel.
Summary of the invention
In order to solve the problem, the invention provides a kind of novel refrigerating machine and circulation thereof.This novel refrigerating machine comprises the parts such as compressor, condenser, choke valve, triple valve or multiple-way valve, generator, evaporimeter and conventional heat engine, and realizes refrigeration by thermodynamic cycle.
This novel refrigerating machine is arranged in a confined space, is full of pressure and is equal to or higher than an atmospheric gas in confined space, and as air or hydrogen or helium, confined space can carry out heat exchange with the external world.
The structure of this novel refrigerating machine condenser is different with the structure of general refrigerator condenser, the condenser of this novel refrigerating machine is an air cylinder group, be made up of two or more cylinders such as cylinder 1 and cylinders 2, object is that the pressure differential utilizing gas to exist with environment after exothermic process in condenser is done work and makes the continuous operation of New Refrigerating function, because gas needs experience in the cylinder closed approximate etc. and puts thermal process and approximate isobaric heat release compression process, these processes all need the time to complete, if condenser is an independent cylinder, novel refrigerating machine can not continuous operation.Cylinder 1 can be connected the outlet of compressor successively with the entrance of cylinder such as cylinder 2 grade.Correspondingly, a triple valve or multiple-way valve are arranged on compressor outlet, and connect the entrance of the cylinder such as cylinder 1 and cylinder 2, will enter the inside of the cylinder such as cylinder 1 or cylinder 2 after cold-producing medium leaves compressor.
The structure of each cylinder of condenser is identical.The entrance and exit of each cylinder has valve, and piston can move in the inside of these cylinders.
Working medium adopts comparatively easily liquefaction and gas-liquid to amass larger cold-producing medium, as ammonia etc.
It comprises two kinds of thermodynamic cycle, for thermodynamic cycle 1:
Cold-producing medium flows through choke valve, evaporimeter, compressor, triple valve or multiple-way valve, condenser successively, finally enters choke valve from condenser.
Cold-producing medium is by adiabatic compression rapidly in compressor, and temperature raises, and pressure increases, and the gaseous refrigerant pressure of compressor outlet is equal to or higher than gas pressure in confined space, and makes gaseous refrigerant discharge compressor.
Gaseous refrigerant is discharged after compressor, is entered in the cylinders such as the cylinder 1 of condenser or cylinder 2, such as, be introduced in cylinder 1 by triple valve or multiple-way valve.During beginning, piston is in the bottom of cylinder 1, and the valve closing of outlet, the valve of cylinder 1 entrance will be opened and connect compressor.The movement of piston will suck cylinder 1 from compressor gaseous refrigerant out, and this process is similar to the breathing process of Otto cycle.When the top of piston arrives cylinder 1, piston is fixed on top, and the valve of entrance and exit all will be closed, and the entrance now taking turns to cylinder 2 connects the outlet of compressor.A series of cylinders for condenser air cylinder group repeat the operation same with cylinder 1.
Owing to can liquefy gradually in gaseous refrigerant temperature-fall period, gaseous refrigerant is allowed first to do approximate etc. to put thermal process in the cylinder 1 leaving compressor outlet closed, until refrigerant temperature drops to equal environment temperature, because gaseous refrigerant is condensed into liquid to conventional heat engine heat release, conventional heat engine absorbs these heats and is used for doing work and generates electricity.
Because gaseous refrigerant is to conventional heat engine heat release and be condensed into liquid, at this time cylinder 1 internal gas pressure will lower than gas pressure in confined space, now the piston at cylinder 1 top will be unclamped, gas pressure in confined space is allowed to do work to piston compression, pressure in cylinder 1 is elevated to and equals gas pressure in confined space, this part merit can be utilized by novel refrigerating machine and generate electricity.
When in cylinder 1, pressure equals gas pressure in confined space, the outlet valve of cylinder 1 will be opened, piston continues move to the bottom of cylinder 1 and liquid refrigerant is discharged cylinder 1, when liquid refrigerant is discharged after cylinder 1, cylinder 1 will reconnect compressor and repeat etc. to put thermal process and compression process.Other cylinder of condenser will experience and same with cylinder 1 etc. put thermal process and compression process.
Liquid refrigerant is discharged after cylinder 1 will enter choke valve, and liquid refrigerant step-down after choke valve is lowered the temperature, then enters evaporimeter, and thus pressure is very low due to the swabbing action of compressor for evaporimeter.Liquid refrigerant self will all be evaporated to gaseous refrigerant from evaporimeter heat absorption, and this gaseous refrigerant is finally inhaled into compressor and carries out next circulation.
For thermodynamic cycle 2;
Thermodynamic cycle 2 is roughly the same with thermodynamic cycle 1, and difference is the thermodynamic process of cold-producing medium in the cylinder of condenser is isobaric heat release compression process.
Namely gaseous refrigerant is discharged after compressor, is entered in the cylinders such as the cylinder 1 of condenser or cylinder 2, such as, be introduced in cylinder 1 by triple valve or multiple-way valve.During beginning, piston is in the bottom of cylinder 1, and the valve closing of outlet, the valve of cylinder 1 entrance will be opened and connect compressor.The movement of piston will suck cylinder 1 from compressor gaseous refrigerant out, and this process is similar to the breathing process of Otto cycle.When the top of piston arrives cylinder 1, the valve of entrance and exit all will be closed, and the entrance now taking turns to cylinder 2 connects the outlet of compressor.A series of cylinders for condenser air cylinder group repeat the operation same with cylinder 1.
Gaseous refrigerant is allowed to make isobaric heat release compression process in the cylinder 1 leaving compressor outlet closed, until refrigerant temperature drops to when equaling environment temperature, because thus gaseous refrigerant is condensed into liquid to conventional heat engine heat release, conventional heat engine absorbs these heats and is used for doing work and generates electricity.
Reduce due to gaseous refrigerant exothermic process temperature and be condensed into liquid gradually, cylinder 1 internal gas pressure will lower than gas pressure in confined space, therefore in confined space, gas pressure will do work to piston compression, pressure in cylinder 1 is elevated to and equals gas pressure in confined space, this part merit can be utilized by novel refrigerating machine and generate electricity.
When in cylinder 1, liquid refrigerant temperature equals environment temperature, the outlet valve of cylinder 1 will be opened, and piston continues move to the bottom of cylinder 1 and liquid refrigerant is discharged cylinder 1.Cylinder 1 will reconnect compressor and repeat isobaric heat release compression process.Other cylinder of condenser can experience and same with cylinder 1 etc. put thermal process and compression process.
Detailed description of the invention
Introduce a specific embodiment below, detailed description of the invention is not limited to this example.
Novel refrigerating machine and general refrigerator closely similar, therefore, general refrigerator can be repacked into novel refrigerating machine.
In order to general refrigerator is repacked into novel refrigerating machine, need, between the compressor outlet and condenser inlet of general refrigerator, a triple valve or multiple-way valve are installed, and condenser is repacked into form air cylinder group by two or more cylinder, the entrance and exit of these cylinders has valve, and piston can move in the inside of these cylinders.
More piston compression is done work to make gas pressure in confined space, this part merit can be utilized by novel refrigerating machine, working medium adopts comparatively easily liquefaction and gas-liquid to amass larger cold-producing medium, as ammonia etc., and makes to be full of pressure in confined space higher than an atmospheric gas.
To enter choke valve after liquid refrigerant eductor condenser, liquid refrigerant is step-down cooling after choke valve, then enters evaporimeter, and thus pressure is very low due to the swabbing action of compressor for evaporimeter.Liquid refrigerant self will all be evaporated to gaseous refrigerant from evaporimeter heat absorption, and this gaseous refrigerant is finally inhaled into compressor and carries out next circulation.
There is temperature difference due to evaporimeter with between condenser and environment, therefore can install conventional heat engine at evaporimeter with between condenser and environment, conventional heat engine utilizes temperature difference to do work and generates electricity.
