But the heat engine using gases is pressed the Stirling periodic duty as working medium, converts heat in the machine of mechanical energy.In the cylinder of heat engine sealing, be filled with the working medium of certain volume.And hot chamber and cold chamber arranged.Working medium is compressed in the cold chamber of low temperature, flows to heating rapidly in the elevated temperature heat chamber then, expansion working, and heat is passed to working medium through hot chamber, and heat dissipation is discharged from cold chamber.
Refrigerator is introduced
Thereby will having, refrigerator obtains the device of cold for surrounding medium the transfer of heat of the object that is cooled of lower temperature.Stirling formula, steam compression type and refrigerating sheet group are arranged.The heat that shifts from the lower temperature object is called cold traditionally.The working medium of participating in the thermal procession variation in the refrigerator is called refrigeration agent.What refrigerator refrigeration coefficient was the highest reaches 7, imports 1 part of energy and just can obtain 7 times cold.The refrigerator of subzero 200 degree of cryogenic temperature has all had batch process last century, and technology is very ripe, subzero 250 degree of cryogenic temperature extensive application also arranged now.
Heat pump promotes heat engine, owing to will produce high temperature and high pressure gas, part and working medium will be operated in hot environment, and is high to material requirements, and it is difficult to cause existing technology to produce, heat pump heat reach 200 spend high temperature also do not have a record.
When ambient temperature is 20 when spending, cryogenic temperature at subzero 200 heat engine theoretical efficiencies up to 73%, when cryogenic temperature theoretical efficiency when subzero 250 spend also only reaches 38% more up to 90% and heat 200 the highest theoretical efficiencies when spending.
Summary of the invention
The present invention proposes a kind of fuel refrigerating environment ability motor of exempting from, and except mechanical energy can be provided, also reduces ambient temperature simultaneously.It overcomes existing heat pump and promotes engine system to material requirements is high, the thermal efficiency is low, especially difficult deficiency of producing; The present invention provides a kind of fuel refrigerating environment ability motor of exempting from; This exempt from the fuel refrigerating environment can motor can all reclaim the mechanical energy of the hot chamber frictional loss of heat engine promote heat engine at once again, the thermal efficiency is high, system is low to material requirements, produce easily.
Refrigerator of the present invention is as long as carry the heat that heat engine dissipates, and coefficient of refrigeration has only 0.1 also can let system normally move, and when the temperature difference is big, also accomplishes easily.And heat pump when promoting coefficient of refrigeration must to be higher than 1 and just possibly move, when the temperature difference is big, be difficult to accomplish.
