Title:
REFRIGERANT CONTROL SYSTEM WITH VARIABLE TEMPERATURE AND VARIABLE PRESSURE FOR CENTRAL AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2014/036935
Kind Code:
A1
Abstract:
A refrigerant control system with variable temperature and variable pressure for central air conditioner is composed of cold and heat source (1), pump (2), refrigerant distribution network, one or more terminal heat exchange apparatus (3) and communication network for connecting every device. The terminal heat exchange apparatus (3) is composed of control point temperature sensor (4), refrigerant outlet temperature sensor (9), refrigerant control valve (5), controller (6), heat exchanger (7) and fan (8). The terminal heat exchange apparatus (3) restricts the flow quantity of refrigerant by the temperature of refrigerant outlet. The pressure of the pump (2) is adjusted by the opening degree of the refrigerant control valve (5) of terminal heat exchange apparatus (3). The transporting temperature of refrigerant is adjusted by the temperature of refrigerant outlet of said terminal heat exchange apparatus (3).
