Abstract
A compartmentalized transport refrigeration system, and method of operating same, in which a host refrigeration unit controls the temperature of the air in a front compartment of a trailer, and a remote evaporator unit controls the temperature of the air in a rear compartment. In order to increase the heating capacity of the remote evaporator, the host's hot gas line is selectively controlled to enable all of the hot gas from the compressor to be directed to the remote evaporator when the host unit is in null. The host unit can only heat when the remote unit is in null. In order to increase the cooling capacity of the remote unit, the host's liquid line in selectively controlled to enable the liquid from the receiver to be all directed to the remote evaporator unit when the host unit is in null.
