  • the thermoelectric cooler 5 is disposed at a level generally higher than the second tubing unit 7 and the evaporator 41 and generally lower than the first tubing unit 6 and the condenser 31.
  • First and second working fluids 30, 40 are respectively injected into the apparatus of the present invention after the first and second tubing units 6, 7, the condenser 31, and the evaporator 41 are evacuated, so that each of the first and second working fluids 30, 40 circulates in a vacuum environment.
  • the first and second working fluids 30, 40 are the same coolant that has a phase-change temperature of about 5-10°C.
  • the first and second working fluids 30, 40 may be a super-thermal-conductive liquid.
  • an air-conditioning method that can be carried out by the air-conditioning apparatus of the present invention includes the steps of evaporating the second working fluid 40, condensing the first working fluid 30, and exchanging heat between the first and second working fluids 30, 40. These steps will be described in greater detail below.
  • the second working fluid 40 is circulated through the closed circulating path formed by the second tubing unit 7 and the evaporator 41 so as to flow upward and downward alternately.
  • the second working fluid 40 which is in a liquid state, evaporates in the evaporator 41 and absorbs heat from air that is drawn into the lower chamber 22 through the lower air inlet 25 by the second fan 42. The air is thus cooled and is discharged through the lower air outlet 26.
  • the vaporized second working fluid 40 flows upward along the channels 413 from the liquid-receiving section 412 and into the vapor-receiving section 411, after which the second working fluid 40 flows further upward to the heat exchange tube section 71 through the vapor-flowing tube section 72.
  • step 82 the vaporized second working fluid 40, when reaching the heat exchange tube section 71, exchanges heat with the first working fluid 30 through the thermoelectric cooler 5.
  • the vaporized working fluid 40 in the heat exchange tube section 71 condenses and flows downward through the liquid-flowing tube section 73.
  • the hot side 53 of the thermoelectric cooler 5 transfers heat from the second working fluid 40 to the heat exchange tube section 61 so that the first working fluid 30 evaporates in the heat exchange tube section 61 and flows upward through the vapor-flowing tube section 62.
  • the first working fluid 30 is circulated through the closed circulating path formed by the first tubing unit 6 and the condenser 31 so as to flow upward and downward alternately.
  • the vaporized first working fluid 30, by condensing in the condenser 31, liberates heat to air which is drawn into the upper chamber 21 through the upper air inlet 23 by the first fan 32.
  • the air becomes hot and is discharged out of the upper chamber 21 through the upper air outlet 24.
  • the condensed first working fluid 30 flows downward along the channels 313 by gravity from the vapor-receiving section 311 into the liquid-receiving section 312 from which the first working fluid 30 flows further downward to the heat exchange tube section 61 through the liquid-flowing tube section 63.
  • the insulating layer 74 of the second tubing unit 7 isolates the liquid-flowing tube section 73 from ambient temperature so that the liquid-state working fluid 40 in the liquid-flowing tube section 73 will not vaporize.
  • the first and second working fluids 30, 40 can undergo self-circulation so that the compressor and the refrigerant controller, usually used in the conventional air-conditioning system 1 (see Figure 1), are unneeded in the present invention. Therefore, the air-conditioning apparatus of the present invention is simple in construction, reduces cost and noise to a minimum, and minimizes self-generated heat.
