Technical field
The present invention relates to a kind of condensed type drying machine with heat pump, described heat pump comprises special evaporimeter and/or condenser, the invention still further relates to a kind of method for optimizing that is used to operate dryer.
Background technology
In condensed type drying machine, air (be called and handle air) is entered in the cylinder that holds moist clothing through heater by the fan conduction, and described cylinder serves as the oven dry chamber.Hot-air absorbs moisture from the clothing of needs oven dry.Behind the process cylinder, moist processing air transmitted was connected with cotton linters filter usually before heat exchanger in heat exchanger.
Drying course comparatively consumes energy, and this is that for the process of the cooling air flow that utilizes heating, the heat of handling in the air flow can lose aspect energy because when the processing air cools off in heat exchanger.This loss of power can obviously reduce by using heat pump.In being equipped with the condensed type drying machine of heat pump, the processing air that contains moisture of heat is obviously cooled off in the evaporimeter of heat pump, and in the evaporimeter there of heat pump, the heat that is transmitted is used for evaporating the cold-producing medium that circulates at heat pump.Supply to the condenser of heat pump by being heated the cold-producing medium that evaporates via compressor,,, discharge heat because gaseous refrigerant is condensed in the condenser there, this heat be used for handle air enter cylinder before the heat treated air.Be included in the moist airborne water of processing in the condensation of evaporimeter place.The water that is condensed is collected in the suitable containers this moment usually, and the processing air of the drying that is cooled is supplied to heater return, turns back to cylinder then.
Described a kind of cloth drying machine among DE 40 23 000 C2, described cloth drying machine has heat pump, and in described cloth drying machine, can enter in the process air channel of opening between thermal source and low-temperature receiver by means of the air of controlled sealing device sealing.
WO 2008/107266 A1 and WO 2008/119611 A1 disclose a kind of cloth drying machine with heat pump.Heat pump in the cloth drying machine is implemented as compact unit usually, and is positioned at the cylinder below of the clothing that is used for the needs oven dry.Do not have the electric heater that is used to handle air.
