Embodiment Construction

[0043] exist figure 1 In condensing dryers, the heat pump is connected to the process air circuit via two subsidiary fluid circuits.

[0044] figure 1 A vertical sectional view of a condensation dryer 1 (hereinafter also referred to as "dryer" 1 ) is shown. figure 1 The dryer 1 shown comprises a drum 3, wherein said drum 3 is rotatable about a horizontal axis, which is used as a drying chamber 3, in which is installed an agitator 4, wherein said agitator is used in the drum Clothes move during spinning. The heater 18, the first heat exchangers 11, 12, 13, the heat pumps 13, 14, 15, 23, the second heat exchangers 16, 17 and the fan 19 are arranged so as to generate a process closed by the air duct 2 through the drum 3 An air circuit 2 to cool the air after passing through the drum 3 and to reheat the air after the moisture contained in the process air has condensed. Here, the air heated by the heater 18 is introduced into the drum 3 from behind (viewed from the side of the ...

Abstract

The invention relates to a condensation dryer (1), comprising a drying chamber (3) for items to be dried, a process air circuit (2), in which the process air can be conducted across the items to be dried by means of a fan (19), and a heat pump circuit (13, 14, 15, 23) for alternately heating and cooling the process air. At least one secondary fluid circuit (12, 20 or 16, 21) is provided between the process air circuit (2) and the heat pump circuit (13, 14, 15, 23). The invention also relates to a method for operating said condensation dryer (1).

Description

technical field [0001] The invention relates to a condensation dryer comprising a drying chamber for items to be dried; a process air circuit in which process air can be guided through the items to be dried by means of a fan; and a heat pump circuit with for alternately heating and cooling process air. [0002] The invention also relates to a method of operating such a condensation dryer. Background technique [0003] Clothes dryers also known as condensation dryers are very popular, the operating principle of which is based on the condensation of evaporated moisture from the laundry with the aid of warm process air, since the dryer produces no Moisture exhaust does not require a hose to remove the exhaust from where this dryer is installed. Therefore, the condensing dryer can be installed in the interior of the bathroom or in the living facilities with a large and complex living environment. [0004] In condensation dryers, process air is introduced by means of a fan via...
