Water heat dissipating system used for condenser coil of water filter apparatus and water filter apparatus

A water filter apparatus comprising:

• a water cooling container;
• a cooling system including a cooling coil and a condenser coil for cyclically circulating refrigerant, so that the refrigerant cooling down water contained in the water cooling container at the cooling coil region and dissipates heat at the condenser coil region;
• a pressure tank;
• at least one water filter unit with a RO filter cartridge for supplying filtered water into the pressure tank and the water cooling container, wherein the RO filter cartridge having a waste water outlet;
• and
• a water heat dissipating system for dissipating heat for the condenser coil of the water filter apparatus, wherein said condenser coil of the water filter apparatus including a bent refrigerant pipeline part with a suitable shape for transferring heat from a refrigerant conducted by the condenser coil to outside,
• wherein the water heat dissipating system comprising:
• a water heat dissipating container for containing water therein, the water heat dissipating container having a water heat dissipating container inlet and a water heat dissipating container outlet to circulate water contained in the water heat dissipating container when there is water supplied to water heat dissipating container inlet;
• wherein:
• the bent refrigerant pipeline part is arranged inside the water heat dissipating container for transferring heat from the refrigerant conducted inside the bent refrigerant pipeline part to the water contained in the water heat dissipating container,
• the water heat dissipating container inlet is connected to at least a waste water outlet of a RO filter cartridge (Reverse Osmosis) of the water filter apparatus,
• wherein said system further including an additional pipeline communicated from a pressure tank of the water filter apparatus to the water heat dissipating container inlet, for supplying water to the water heat dissipating container inlet, at least when water is stored full in the pressure tank and having a high pressure.
