The specific embodiment
Embodiment based on shown in accompanying drawing is described to the present invention in more detail below.
As shown in fig. 1, for the use heat exchanger of target of the present invention and the compressor cooling system of precondenser comprise: the compressor 1 associated with precondenser 7, with heat exchanger 91, this heat exchanger is arranged in the housing 2 of compressor 1 and cooperates with precondenser 7.
Fig. 5 at length represents that compressor 1 comprises: housing 2, compression cylinder 3 and its corresponding lid 4(are except being used the situation of the micro-compressor without inner cover) be positioned at this housing, the outlet 6 that carrys out the inlet tube 5 of flash-pot (not shown) and fluid compressed and that process is directed in condenser (not shown) stretches out from housing 2, compressor 1 is also equipped with the pipeline (or pipe) 8 and 1 with precondenser 7 interconnection, this pipeline cooperates with precondenser, precondenser 7 is supplied with by the pipeline 8 that is positioned at the compression cylinder 3 of compressor 1, as noticed better from Fig. 5 and 6.
According to the preferred embodiments of the present invention shown in Fig. 1 and 2, heat exchanger 91 comprises pipeline, and this pipeline is arranged around compressor or micro-compressor 1 housing, completely or partially coated this housing.
According to this structure, because precondenser 7 is worked under identical condenser temperature with refrigeration system, guarantee that the compressor 1 being coated by heat exchanger 91 will have the low temperature (due to the heat of evaporation exchange occurring in the pipeline 91 of arranging around compressor 1) of the condensation temperature of approaching.
Merit attention, compressor cooling system and be equipped with the compressor self of cooling system can comprise the other heat exchanger 9 being arranged in compressor 1, this other heat exchanger and heat exchanger 91 and precondenser 7 in series operate.
This other inner heat exchanger 9 is preferably arranged in the heat part near compressor 1 in housing 2, inner heat exchanger 9 receives fluids by being connected to the elastic tube 10 of end of the outlet 11 of precondenser 7 from precondenser 7, and by output elastic tube 12, processed fluid is wherein directed in discharge pipe 6.
Fig. 5 illustrates the first structure possibility, thus identical compression cylinder that is operationally connected to compressor 13 of described other inner heat exchanger 9.
Other embodiment of the present invention shown in Fig. 6, wherein, when lid (note, micro-compressor does not provide inner cover) exists, other inner heat exchanger 9 is connected to the lid 4 of compression cylinder 3.
System of the present invention is transported to the heat from compressor 1 inside in external environment condition with the gas self of compressed machine 1 compression and pumping.Conventionally, the gas of use is along its path in compressor 1 by lid 4, discharge filter, the discharge line of compression cylinder 3 and finally enter condenser (not shown) by discharge pipe 6.
When leaving compressor 1, the gas of compression discharges heat to external environment condition by precondenser 7, and in this precondenser, cooling agent is introduced to zone of saturation.The coolant temperature of the end of precondenser 7 (this cooling agent can be considered to two-phase now) is self condensation temperature of refrigeration system.Cooling agent is when turning back to compressor 1 when leaving heat exchanger 7 compared with low-lying level (enthalpy) and along the directed piping 91 of all outer surfaces of the housing 2 of compressor 1.Then dual phase coolant exchanges sensible heat and latent heat with the heated body of compressor, reduces its temperature.After completing heat exchange, this fluid is introduced to discharge pipe 6, and this discharge pipe forms the fastener of other parts of compressor 1 and refrigeration system subsequently.
Be worth emphasizing, heat exchanger 91 has following functions: from the heat part of compressor 1, remove heat, and the gas therefore sucking in path and compression by superheated is reduced the loss.The use of heat exchanger also guides case temperature and the condensation temperature interconnection of compressor 1, then when operating under high room temperature, prevents that compressor 1 from subsiding.
In addition, precondenser 7 allows the surface temperature that maintains compressor to approach very much system condensing temperature, and this is only difficult to realize by ventilation.
In the situation that the system illustrating is used other heat exchanger 9, the example of the parts that can be cooled comprises the lid 4 of compression cylinder 3 and compression cylinder 3.
When the parts that will be cooled are compression cylinder 3, as shown in Figure 6, compressed fluid leaves compressor 1 by pipeline 8, releasing heat in precondenser or external heat exchanger 7, and turn back to compressor 1 by the outlet 11 of precondenser 7.When entering compressor 1 again, the fluid being cooled is directed in the inner heat exchanger 9 that is connected to compression cylinder 3 by elastic tube 10.When leaving inner heat exchanger 9, this fluid is sent in discharge pipe 6 by another elastic tube 12, and this discharge pipe is the fastener that compressed fluid is transported to condenser or refrigeration system.
The wall temperature of the low cylinder 3 of heat drop of exchange in compression cylinder 3, and further reduce the fluid temperature (F.T.) in suction chamber S; Therefore, external except entering the colder coolant flow of cylinder 3, heating be wherein reduced and between compression period the heat exchange to wall be maximized, for compression process provides larger thermodynamic efficiency.
Alternatively, as shown in Figure 5, inner heat exchanger 9 can be connected to the lid 4(of compression cylinder 3 when existing).In this structure, compressed fluid leaves compressor 1 by the service (pipe) 8 of precondenser 7, releasing heat in precondenser 7, and turn back to compressor 1 by managing 11.When entering compressor 1 again, the fluid being cooled is directed in the inner heat exchanger 9 of the lid 4 that is connected to compression cylinder 3 by elastic tube 10.Situation about occurring in the embodiment providing is above provided, and when leaving inner heat exchanger 9, this fluid is introduced in discharge pipe 6 by another elastic tube 12, and this discharge pipe is guided to compressed fluid in the condenser of refrigeration system.
In the lid 4 of cylinder 3 heat of exchange reduced in all parts of cylinder head and in the temperature of compressed gas.Because compressed gas is the main thermal source of compressor 1, reduce the bulk temperature reduction that its temperature causes compressor 1 parts.Therefore, initial compression temperature reduces, and this causes higher thermodynamic efficiency in compression process.
For realizing target of the present invention, adopt the benefit of the compressor cooling system that uses precondenser 7 to relate to reliability and energy efficiency aspect.About reliability, the heat part of the compressor 1 being caused by the system proposing cooling avoids critical-temperature, and under this critical-temperature, the oil existing in compressor 1 will suffer the irreversible change of degraded and its thermophysical property.
Yet maximum benefit is relevant with the energy efficiency of the increase of compressor 1.By the heat part from compressor 1, heat is transported to external environment condition, sucks superheated gas in path and reduce, in the density increase that starts to cause cooling agent of compression process, and therefore increase by the quality of compressor 1 compression and pumping.Therefore, the coefficient of performance of compressor 1 (COP) is large.
Generally, the scheme of proposition also produces the benefit of the operation of refrigeration system.By adding precondenser 7, there is the larger heat exchange in external environment condition, cause cycling through the lower temperature of the cooling agent of discharge pipe 6.Therefore, at cooling agent, in the situation that be transported to cooling system at lower temperature, condenser size is excessive, causes the reduction of condenser system pressure.
Therefore, this has improved the efficiency of kind of refrigeration cycle, because it has reduced the required temperature difference of heat exchange.In addition, because condenser becomes oversize, destroy surge pressure and also reduce, this is concerning the very important situation of compressor 1, in this case, may due to the load in compressor and temperature is excessive rolls.
Tellable, although preferable configuration mode of the present invention has been shown, should be appreciated that those skilled in the art can realize any omission, substitute and structural change, and do not depart from claimed spirit and scope.Also clearly regulation, with substantially the same mode carry out identical function with realize identical result element all combinations within the scope of the invention.Also can expect and imagine the element that replaces described embodiment with other element completely.Yet, should be appreciated that the description providing based on above-mentioned accompanying drawing only relates to some of embodiment possible for system of the present invention, the true scope of target of the present invention is defined in claims.
