Summary

REPORT OF A TEST STUDY. DEHUMIDIFICATION BY A HEAT PUMP IN A 3,000 M2 INFLATABLE JACKETED GREENHOUSE, HOUSING ROSE CROPS, IN WHICH ABUNDANT CONDENSATION DEVELOPS ON THE INTERNAL WALLS OF THE GREENHOUSE AND WHICH, FALLING IN DROPLETS ON THE PLANTS AND THE SOIL, CREATED AN INTERNAL CLIMATE HAZARDOUS TO THE PHYTOSANITARY CONDITION OF CROPS. THE PLANT AND THE CHARACTERISTICS OF THE TWO HEAT PUMPS USED ARE DESCRIBED ; THE INSTRUMENTATION INSTALLED AND THE RESULTS OBTAINED ARE REPORTED. ALTHOUGH NO SIGNIFICANT DECREASE IN INTERNAL RELATIVE HUMIDITY HAS BEEN SHOWN (PROBABLY DUE TO AN OPPOSED INCREASE IN EVAPOTRANSPIRATION OF THE PLANTS) IT APPEARS THAT THE WATER EXTRACTION OBTAINED, EVEN SMALL, SUFFICIENTLY CHANGES THE CONDENSATION PROCESS TO CREATE A HEALTHIER ENVIRONMENT AND SOLVE PHYTOSANITARY PROBLEMS.
