Humidity and temperature control in vapor compression system

A vapor compression system, comprising:

• a vapor compression circuit comprising a compressor, a condenser, an expansion device and an evaporator serially connected by refrigerant lines;
• an air flow path through said evaporator for generating a cooled air stream;
• a heat exchanger communicated with said cooled air stream and an air reheating medium comprising at least one of refrigerant liquid discharge from said condenser and refrigerant gas discharge from said compressor;
• a regulating valve for controlling flow rate of said air reheating medium to said heat exchanger;
• and
• a control member communicated with said expansion device for controlling refrigerant flow to said evaporator, and communicated with said regulating valve for controlling flow rate of said air reheat medium to said heat exchanger, whereby simultaneous control of temperature and humidity of said cooled air stream can be provided.
