Abstract: A refrigeration system and a start control method for a refrigeration system. The refrigeration system includes: a refrigeration loop having an exhaust port of a compressor, a condenser, a throttle element, an evaporator, and a suction port of the compressor connected in sequence by using a flow path; wherein a first valve is disposed between the throttle element and the condenser, and the first valve is at least capable of cutting off a refrigerant flow from the throttle element to the condenser; and a second valve is disposed close to the suction port of the compressor, and the second valve is used to control on/off of a flow path between the evaporator and the compressor. Starting load of the refrigeration system according to the present invention can be effectively reduced, so that the power and size of a drive component for providing power can also be reduced.

Abstract: A method of controlling a refrigeration system having a compressor (22), a condenser (24), an evaporator (28), and a variable speed condenser fan (44) is provided. The method includes determining if a change in an ambient temperature or a compressor suction pressure is greater than a predetermined threshold, determining a near-optimal condensing pressure/temperature if the change in the ambient temperature or the compressor suction pressure is above the predetermined threshold, setting a condensing pressure setpoint based on the determined near-optimal condensing pressure/ temperature, and setting a speed of the variable speed condenser fan based on the condensing pressure setpoint.
