A controller (102, 302) for frost management of an evaporator, comprising: a memory; a processor configured to execute executable instructions stored in the memory to: receive operating information of a heat pump; determine a first set point of at least one of a number of components of the heat pump and a first operating temperature of an evaporator that correspond to operation of the heat pump at a first operating energy efficiency based on the operating information of the heat pump to cause the heat pump to operate in a heating mode for a first heating interval length at the first operating temperature such that the heat pump operates at an optimum coefficient of performance; receive a second operating temperature of the evaporator that is positively offset from the first operating temperature of the evaporator associated with the operating information of the heat pump; determine a second set point of at least one of the number of components of the heat pump that correspond to an operation of the heat pump at a second operating energy efficiency corresponding to the second operating temperature of the evaporator of the heat pump based on the operating information of the heat pump to cause the heat pump to operate in the heating mode for a second heating interval length corresponding to the second operating temperature such that the heat pump operates at a COP that is less than the optimum COP; and modify a set point of at least one of the number of components of the heat pump to the second set point to enable the heating mode of the heat pump for the second heating interval length of the heat pump that is longer than the first heating interval length of the heat pump. a memory; a processor configured to execute executable instructions stored in the memory to: receive operating information of a heat pump; determine a first set point of at least one of a number of components of the heat pump and a first operating temperature of an evaporator that correspond to operation of the heat pump at a first operating energy efficiency based on the operating information of the heat pump to cause the heat pump to operate in a heating mode for a first heating interval length at the first operating temperature such that the heat pump operates at an optimum coefficient of performance; receive a second operating temperature of the evaporator that is positively offset from the first operating temperature of the evaporator associated with the operating information of the heat pump; determine a second set point of at least one of the number of components of the heat pump that correspond to an operation of the heat pump at a second operating energy efficiency corresponding to the second operating temperature of the evaporator of the heat pump based on the operating information of the heat pump to cause the heat pump to operate in the heating mode for a second heating interval length corresponding to the second operating temperature such that the heat pump operates at a COP that is less than the optimum COP; and modify a set point of at least one of the number of components of the heat pump to the second set point to enable the heating mode of the heat pump for the second heating interval length of the heat pump that is longer than the first heating interval length of the heat pump. receive operating information of a heat pump; determine a first set point of at least one of a number of components of the heat pump and a first operating temperature of an evaporator that correspond to operation of the heat pump at a first operating energy efficiency based on the operating information of the heat pump to cause the heat pump to operate in a heating mode for a first heating interval length at the first operating temperature such that the heat pump operates at an optimum coefficient of performance; receive a second operating temperature of the evaporator that is positively offset from the first operating temperature of the evaporator associated with the operating information of the heat pump; determine a second set point of at least one of the number of components of the heat pump that correspond to an operation of the heat pump at a second operating energy efficiency corresponding to the second operating temperature of the evaporator of the heat pump based on the operating information of the heat pump to cause the heat pump to operate in the heating mode for a second heating interval length corresponding to the second operating temperature such that the heat pump operates at a COP that is less than the optimum COP; and modify a set point of at least one of the number of components of the heat pump to the second set point to enable the heating mode of the heat pump for the second heating interval length of the heat pump that is longer than the first heating interval length of the heat pump.
