Evaporative fluid-cooler with integrated mechanical cooling system

An apparatus with an integrated mechanical cooling system for cooling an enclosed space and rejecting heat from a process fluid, the apparatus comprising:

• a. a first section where ambient outdoor air enters the apparatus and rejects the heat from the process fluid that returns from the enclosed space, wherein the process fluid may comprise the following:
• i. water, Glycol, mixture of water and Glycol, refrigeration fluid, or any non-conductive fluid returning from the enclosed space or a second apparatus inside or outside of the enclosed space;
• b. ambient outdoor air openings on both sides of the apparatus along a length of the apparatus that allows the ambient outdoor air to enter the first section;
• c. a second section comprising:
• i. an evaporative cooling system that uses a water spray system that cools the entering ambient outdoor air;
• ii. a liquid-to-air heat exchanger (or exchangers) located downstream from the water spray system that rejects heat from the process fluid to the air;
• iii. a water collection pan under the liquid-to-air heat exchanger(s) that collects any excess water that drips from the liquid-to-air heat-exchanger(s);
• iv. at least one water pump to direct the water to the water spray system;
• v. water feed and water drain lines and valves that keep the water level in the water collection pan at a desired level;
• vi. one or more condenser coils that are located downstream from the liquid-to-air heat exchanger(s) to reject the heat from a refrigerant;
• and
• vii. wherein the refrigerant is a distinct heat exchange medium and is independent from the process fluid;
• d. a third section comprising an air movement means, such as an exhaust air fan(s), that moves air from the apparatus to the ambient outdoor air;
• and
• e. a fourth section comprising an assisted mechanical cooling system, comprising:
• i. an expansion valve that adjusts the pressure of the refrigerant flowing from the condenser coil(s) before entering a liquid-to-refrigerant heat-exchanger (LRHX) to lower pressure of the refrigerant;
• ii. wherein the LRHX transfers heat from the process fluid to the refrigerant;
• iii. a compressor (or compressors) that increases the pressure of the refrigerant;
• iv. a three-way valve that directs the process fluid from the liquid-to-air heat-exchanger(s) to at least one of the following locations:
• 1. the LRHX;
• 2. a liquid-to-liquid heat exchanger;
• 3. the enclosed space;
• 4. an end user;
• 5. a liquid-to-air heat exchanger;
• and
• v. at least one process fluid pump.
