A self-contained climate control system for simultaneous temperature and humidity control in a wine cellar includes a refrigeration system having a conventional vapor-compression system including a condensate drip tray with over-flow passages. A programmable controller with a temperature sensor turns the compressor on and off by responding to the temperature sensor to regulate the air temperature in the wine cellar. The programmable controller keeps the system fans running after the compressor stops to cause evaporation of the water in the drip tray, restoring the moisture to the wine cellar.
