A greenhouse (10) for growing plants, comprises a growing area (12) for growing crops and a climate control system for controlling the greenhouse interior climate in the growing area. This control system comprises a condenser (48) for dehumidifying greenhouse air , a greenhouse air heat exchanger (32) for heat-exchange between greenhouse air derived from the growing area upstream of the air inlet of the condenser and in the condenser dehumidified greenhouse air downstream of the air outlet of the condenser, a first controllable bypass (42； 55) for allowing greenhouse air to bypass the greenhouse air heat exchanger, a controllable fan (56) , a mixing chamber (14) in fluid communication with the air discharge of the heat exchanger and with the growing area and having a controllable inlet (62) for introducing ambient air from the greenhouse exterior environment, and an outlet (65) having a controlled fan (17) for air in fluid communication with the growing area.
