摘要:
A method of operating a heat pump clothes dryer operating on a mechanical refrigeration cycle is disclosed. The method includes partitioning all energy available in the heat pump clothes dryer into a first amount of energy and a second amount of energy; using the first amount of energy to attain a standard parameter performance for the heat pump clothes dryer; and using the second amount of energy to accelerate a dry cycle of the heat pump clothes dryer, wherein using the second amount of energy to accelerate a dry cycle of the heat pump clothes dryer comprises using the second amount of energy to energize an auxiliary heater during a start transient phase of the dry cycle to decrease the start transient phase.
摘要:
An apparatus includes a mechanical refrigeration cycle arrangement having a working fluid and an evaporator, a condenser of adjustable surface area, a compressor, and an expansion device, cooperatively interconnected and containing the working fluid. The apparatus also includes a drum to receive clothes to be dried, a duct and fan arrangement configured to pass air over the condenser and through the drum, a sensor located to sense at least one parameter, and a controller coupled to the sensor, condenser and/or the compressor. The controller is operative to adjust the condenser to increase surface area during a steady state drying rate period of the cycle, and adjust the condenser to decrease surface area during a start transient period of the cycle, wherein adjusting the condenser to decrease surface area during a start transient period of the cycle accelerates the start transient period of the cycle.

An apparatus includes a mechanical refrigeration cycle arrangement in turn including an evaporator, a condenser, a compressor, and an expansion device, cooperatively interconnected. A drum is provided to receive clothes to be dried. An auxiliary heater is included, as is a duct and fan arrangement configured to pass air over the condenser and the heater, and through the drum. A sensor is located to sense high side temperature and/or high side pressure of the mechanical refrigeration cycle arrangement. A controller is coupled to the sensor and the auxiliary heater, and is operative to: activate the auxiliary heater during a startup transient of the mechanical refrigeration cycle arrangement; monitor the high side temperature and/or high side pressure, during the startup transient; and de-activate the auxiliary heater in response to the high side temperature and/or high side pressure reaching a first predetermined value.

The apparatus also includes a drum to receive clothes to be dried, a duct and fan arrangement configured to pass air over the condenser and through the drum, a sensor located to sense at least one parameter, and a controller coupled to the sensor and/or the compressor. The parameter(s) includes at least one of temperature of the working fluid, pressure of the working fluid, and power consumption of the compressor. The controller is operative to monitor, as a function of time, the parameter(s), determine whether the parameter(s) reaches a predetermined decision condition; and, if the parameter(s) reaches the predetermined decision condition, power down the mechanical refrigeration cycle at least by causing the compressor to shut off.
