Description
Technical field
The utility model relates to a kind of heat-exchange system, and particularly a kind of high efficient heat exchanging system for field of air conditioning belongs to air-conditioning heat exchange field.
Background technology
Common central air conditioner system for from condenser out the liquid coolant heat and all effectively do not recycle from evaporator outlet gas coolant heat out.
Chinese patent literature CN102095268A discloses a kind of aircondition of the propane refrigerant with regenerator, this device is done change in original air-conditioning system, added regenerator, described regenerator has the inner tube import that is communicated with the outlet of condenser and the inner tube that is communicated with electric expansion valve outlet, the outlet of described expansion valve is communicated with the import of evaporimeter, the outer tube import of the outlet of evaporimeter and regenerator is communicated with, the outer tube outlet of regenerator is communicated with compressor inlet, and compressor outlet is communicated with condenser.This kind aircondition is by increasing regenerator, making can be to lowering the temperature from condenser liquid refrigerant out from evaporimeter gas coolant out, thereby make the temperature of the refrigerator that enters evaporimeter further reduce, thereby improved the volatility of evaporimeter, and then improved the refrigeration performance of whole aircondition.But this aircondition does not relate to the improvement of condenser and evaporimeter internal structure, and adopts existing conventional condenser and the structure of evaporimeter.
What the condenser of existing conventional central air-conditioning adopted basically is pipe heat exchanger, and cold-producing medium carries out heat exchange by the heat exchanger tube that is arranged in outer cover of heat exchanger with extraneous water, realizes refrigeration.For the condensation efficiency that makes condenser is further improved, liquid outlet end at trumpet cooler, generally also be provided with supercooling tube, guarantee further cooling from the condenser fluid, but in this kind method, the low-temperature receiver of supercooling tube is the cooling water that enters from the external world, is subjected to the restriction (30 ℃ of left and right of coolant water temperature) of low-temperature receiver, the degree of supercooling of this condenser is relatively low, and heat exchange efficiency is also relatively low.Because can only being communicated with the cooling water of GB requirement, this supercooling tube can not be communicated with other coolant medias; Therefore, as new technological trend, in the middle of the application of trumpet cooler, set up at the fluid pipeline section of condenser and be equipped with board-like subcooler, utilize board-like subcooler to realize the heat exchange between the cryogenic refrigeration medium after refrigerant and throttling, further improve the degree of supercooling of condenser, so just can improve simultaneously whole unit refrigerating capacity.But the structure of this split type condenser is very complicated, and parts are various, and trouble is installed, and overall volume is larger, takes up room also larger, makes the floor space of whole central air-conditioning larger.
Complicated for solving condenser structure, the problem that dutycycle is higher, U.S. patent documents US2010/0065262Al discloses a kind of plate type heat exchanger, and it can be used as condenser and uses.The heat exchanger structure of its relative tubular type is simple, and floor space is little; But it does not make further cooling supercooling apparatus of condenser, and therefore, the condensation efficiency of this condenser can not meet the demands.And in prior art, it is also the split-type structural that connects by pipeline that this board-like condenser installs subcooler additional.Its floor space still can not satisfy the requirement of compact central air conditioner system.
Chinese patent file CN2604667Y discloses a kind of preheating, sterilization, cooling plate type heat exchanger of integrating.For solve sterilization and quick cooling employing two cover autonomous devices in prior art move simultaneously the using energy source of existence insufficient, waste water and problem that equipment investment is large.This heat exchanger is that the multi-disc plate type heat exchanger is closely connected, set up flow deflector in the centre and formed waste heat exchange area and high-temperature sterilization district, it is by pre-backing 1, sterilization sheet 4, fin 2, flow deflector 3 and high-temperature heating sheet 5 form, cold liquid is through preheating and sterilization, flows out emit heat in fin after, and high-temperature medium can be with hot water or superheated vapor, emit heat in heating plate, can fully exchange because they connect tight heat.But the interior shape of the deflector 3 in this plate type heat exchanger is parallelogram, can cause rate of flow of fluid too small during fluid process deflector 3, finally causes heat exchange efficiency lower, can not satisfy the requirement of the condenser heat exchanging efficient in central air-conditioning.
Therefore, the heat-exchange system for field of air conditioning of the prior art can't satisfy compact conformation and the high advantage of heat exchange efficiency simultaneously.
