The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As Fig. 1, integrated thermal combined air conditioner shown in Figure 2, comprise aircondition and heat-pipe apparatus, aircondition is by compressor 10, condenser 20, capillary 30, evaporimeter 40, gas-liquid separator 50 connects into the loop by pipeline successively, heat-pipe apparatus is by heat pipe condenser 60, heat pipe evaporator 80 connects into the loop by pipeline successively, wherein heat pipe condenser 60 is positioned at the top of heat pipe evaporator 80, heat pipe condenser 60 and the shared blower fan 100 of condenser, heat pipe evaporator 80 and evaporimeter 40 shared centrifugal blowers 110, the air inlet of condenser 20 is provided with first temperature sensor, the air inlet of evaporimeter 40 is provided with second temperature sensor, first temperature sensor, second temperature sensor, compressor 10, blower fan 100, centrifugal blower 110 links to each other with controller respectively.

The utility model is on the basis of original air-conditioning, an integrated cover heat pipe, as shown in Figure 2, be that heat pipe evaporator 80 is positioned on the same passage with former A/C evaporator 40, its indoor centrifugal blower 110 is shared, heat pipe condenser 60 is positioned on the same passage with condenser 20, and its blower fan 100 is shared, forms the overall structure of an air-conditioning and heat pipe thus.When inside fills an amount of cold-producing medium, utilize evaporation side gasification heat absorption, the hot pipe technique of condensation side liquefaction heat release under the effect of liquid refrigerant deadweight, forms the heat pipe circulation naturally.

In the prior art, heat-pipe apparatus must be closed air door with air-valve when not enabling, form a confined space in condensation side, owing in most cases all be directly inboard evaporator section derivation from the air conditioning chamber with hot tube bundle, there are not transition connecting leg and stop valve freely, so the seal of condensation side is often unreliable.As preferred version of the present utility model, on the pipeline between the input of the output of heat pipe condenser 60 and heat pipe evaporator 80, be provided with first stop valve 70, be provided with second stop valve 90 between the input of the output of heat pipe evaporator 80 and heat pipe condenser 60, controller links to each other with first, second stop valve 70,90.By setting up first,

second stop valve

70,90, when not needing heat-pipe apparatus work, can block, to reduce influence, guarantee the sealing and the heat insulating ability of former air-conditioning evaporation side to former heat pump performance, simultaneity factor is relatively independent, and is simple in structure.

In order to ensure liquid refrigerant in the heat pipe circulation in gravity effect current downflow, most preferred scheme be heat pipe condenser 60 be positioned at heat pipe evaporator 80 directly over, as shown in Figure 2, it is poor that promptly both layouts will keep certain height; The internal duct of heat pipe evaporator 80 and heat pipe condenser 60 is for horizontally disposed or be arranged vertically from top to bottom, can not cross arrangement, the material of heat pipe evaporator 80, heat pipe condenser 60 adopts the finned copper pipe heat exchanger of common air-conditioning, and its heat exchange area is determined according to the heat exchange measuring.Cold-producing medium in the heat-pipe apparatus can adopt HCFC, HFC or natural medium to finish, should consider the influence of factors such as heat-conducting system, viscosity, boiling point, critical pressure, flammability and the feature of environmental protection when selecting for use, as preferred version, can select the cold-producing medium identical with air-conditioning, be convenient to maintenance in the future.

During use, controller is to determine to start air conditioning mode or heat pipe pattern by the temperature difference that reads between first temperature sensor and second temperature sensor, what aircondition of the present utility model partly adopted is ripe vapor compression refrigeration technology, and workflow is: compressor 10 → condenser 20 → capillary 30 → evaporimeter 40 → gas-liquid separator 50 → compressor 10; Its refrigeration principle is: compressor 10 absorbs the refrigerant gas of the low-temp low-pressure of flash-pot 40, the gas that is compressed into HTHP enters condenser 20 and is condensed into liquid, emit condensation heat, liquid becomes the liquid of low-temp low-pressure after capillary 30 throttlings, enter evaporimeter 40, liquid evaporates heat absorption in evaporimeter 40 after, become gas again, finally sucked compression once more, so move in circles, finish refrigeration work by compressor.

The workflow of heat-pipe apparatus part is: heat pipe evaporator 80 → the second stop valves 90 → heat pipe condenser 60 → the first stop valves 70 → heat pipe evaporator 80; Its refrigeration principle is: after cold-producing medium absorbs heat in heat pipe evaporator 80, become the gas that certain pressure is arranged, flow to heat pipe condenser 60 through second stop valve 90, form liquid after the heat release, because the position of heat pipe condenser 60 is higher than heat pipe evaporator 80, under the gravity effect, return in the heat pipe evaporator 80 through first stop valve 70 and time liquid are curved, so move in circles, finish the heat pipe ringing.
