A transport refrigeration system which includes a compressor, a condenser, a receiver, an evaporator, an accumulator, and a control valve which selectively initiates heating and cooling cycles. The heating capacity of a heating cycle is enhanced by connecting the outlet of the receiver to the inlet
A transport refrigeration system which includes a compressor, a condenser, a receiver, an evaporator, an accumulator, and a control valve which selectively initiates heating and cooling cycles. The heating capacity of a heating cycle is enhanced by connecting the outlet of the receiver to the inlet of the accumulator just prior to each heating cycle, while maintaining the control valve in a cooling position for a predetermined time delay. This forces any liquid refrigerant trapped in the condenser to flow into the receiver, while lower pressure in the accumulator causes liquid refrigerant in the receiver to flow into the accumulator, to provide additional liquid refrigerant in the accumulator at the start of the heating cycle, which is initiated at the end of the predetermined time delay.

In a transport refrigeration system which holds a set point temperature via heating and cooling cycles, a refrigerant circuit which includes a compressor, condenser, receiver, evaporator, and accumulator, mode selector valve means having heating and cooling positions, and control means for providing
In a transport refrigeration system which holds a set point temperature via heating and cooling cycles, a refrigerant circuit which includes a compressor, condenser, receiver, evaporator, and accumulator, mode selector valve means having heating and cooling positions, and control means for providing a heat signal when the need for a heating cycle is detected, the improvement comprising: means responsive to said heat signal for connecting the receiver and accumulator in direct fluid flow communication, and time delay means responsive to said heat signal which operates said mode selector valve means from the cooling position to the heating position after a predetermined time delay, whereby a condenser flushing mode occurs prior to each heating cycle, which forces liquid refrigerant trapped in the condenser to flow to the accumulator via the receiver, to enhance the heating capacity of the system.
