    The liquid refrigerant evaporates inside the coil as it absorbs heat from the air. The refrigerant gas then travels through refrigerant piping to the outdoor unit, where it is pressurized in an electrically driven compressor, raising its temperature and pressure, and returned to a liquid state in the condenser as it releases, or dumps, the heat to the outdoors.

    2008-8-24 · The initial cool-down of the dewar takes about 12-18 hours, after which liquid nitrogen is produced at a net rate of 1 liter per day. The generator uses about 300 to 400 watts of electricity (includes the water chiller, which cycles on and off), so the energy cost for producing one liter of liquid nitrogen is about 8.5 KWh, or 1.10.

    The heat removed from the condensed vapor is transferred to a cooling medium such as air or water. Physically, this step takes place in a heat exchanger serving as a condenser • Step 3: Expansion: the pressure of the liquid is released through a throttling element (e.g. an expansion valve), down to pressure P 1 (Point 4). The throttling process is supposed to be isenthalpic, not involving any exchange of energy.

    Electricity from the PV/T module drove the DC compressor directly without using batteries. Water in the ice storage tank was used as cold storage material. When there was demand of cooling, water in the ice storage tank was pumped into the indoor fan-coil to cool the air. The schematic diagram of the ice storage tank is shown in Fig. 3. The spiral pipe evaporator was set in the ice storage tank.
