Abstract
A compressor type air cooler is combined with a booster comprising an evaporative air precooler, a refrigerant vapor precooler and a refrigerant liquid cooler. This makes the compressor type cooler usable in localities where the ambient temperature is so high as to prohibit use of the compressor type cooler alone, and saves a notable amount of electrical power at any ambient temperature.
Claims4
A refrigerative evaporative booster combination comprising:
- a refrigerative air cooler containing a fluid refrigerant and a condenser, said condenser containing a refrigerant pipe unit having a pipe input and a pipe output;
- a condenser fan passing air through said condenser;
- an evaporative air cooler containing at least one water-dampened cooler pad, containing a water-cooled pipe unit and containing a sump collecting excess water from said at least one pad and from the water-cooled pipe unit;
- pipes containing a refrigerant, said pipes interconnecting said refrigerative air cooler and said evaporative air cooler;
- and
- air duct means interconnecting said refrigerative air cooler and said evaporative air cooler whereby air moved by said condenser fan passes successively through said at least one cooler pad and said condenser.
