Refrigeration unit with heat exchanging arrangement

A refrigeration unit, comprising:

• a plurality of connecting pipes for allowing heat exchange media to pass therethrough;
• a compressor having a compressor input port and a compressor output port;
• a four-way reversing valve connected to said compressor through said connecting pipes;
• a first heat exchanger connected to said compressor through said four-way reversing valve and at least one of said connecting pipes, said first heat exchanger having a first connection port, a second refrigerator port, a water inlet and a water outlet;
• a second heat exchanger connected to said compressor and said first heat exchanger through at least one of said connecting pipes, said second heat exchanger having a third connection port and a fourth connection port;
• a heat transfer fan communicated with the second heat exchanger for drawing air to perform heat exchange with said heat exchange medium flowing through said second heat exchanger;
• a water pump having a water input port and a water output port, said water output port being connected to a water inlet of said first heat exchanger;
• and
• a heat exchanging arrangement, which comprises:
• a main casing having a receiving cavity divided into at least one water atomizing compartment and one water showering compartment, an air inlet communicating with said water atomizing compartment of said receiving cavity, and an air outlet communicating with said water showering compartment of said receiving cavity;
• a fan provided in said main casing for drawing ambient air to enter said main casing through said air inlet and exit said main casing through said air outlet;
• at least one water atomizing unit provided on said water atomizing compartment and connected to said water output port of said water pump through at least one of said connecting pipes;
• at least one water showering head provided on said water showering compartment and connected to said water outlet of said first heat exchanger;
• at least one fill material unit provided underneath said water showering head;
• and
• a water collection basin provided underneath said water atomizing unit and said fill material,
• wherein a predetermined amount of water in said first heat exchanger is arranged to be guided to flow to said water showering head through said water outlet and through at least one of said connecting pipes, said water in said water showering head being sprinkled on said fill material unit and collected in said water collection basin,
• wherein a predetermined amount of water from said water output port of said water pump is guided to flow to said water atomizing unit through at least one of said connecting pipes, said water flowing to said water atomizing unit being sprayed and atomized in said water atomizing compartment,
• said ambient air being drawn to sequentially pass through said water atomizing compartment and said water showering compartment, said water collected in said water collection basin being guided to flow into said water pump through said water input port and at least one of said connecting pipes.
