Multipurpose drying apparatus using heat pump system

Abstract

The invention provides a multipurpose drying apparatus using heat pump system. According to one side of the invention, the multipurpose drying apparatus is characterized in that the drying is performed through a heat pump system, the heat pump system circulates the refrigerant by means of a compressor, a main condenser and a main evaporator, the multipurpose drying apparatus using heat pump system includes a drying apparatus body, wherein a main condenser and a main evaporator are provided to perform heat exchange; and a drying chamber formed inside the drying apparatus, to perform drying to drying objects. The heat pump system includes an auxiliary condenser, provided at the external of the drying apparatus body, and is configured to selectively link between the compressor and the main condenser, so as to reduce the temperature inside the drying apparatus body.

Description

technical field [0001] The present invention relates to a drying device, and specifically relates to a multipurpose drying device capable of drying an object to be dried in the drying device through heat exchange through a condenser and an evaporator, and preventing the temperature in the drying device from rising to the level of the device. Above a certain temperature, for the drying object that requires more heat, it can be adjusted to provide sufficient heat for drying, and it can also greatly improve the drying efficiency. Background technique [0002] Recently, with the advancement of industrialization, the discharge of raw waste represented by various household wastes has increased rapidly due to population increase and population concentration. Moreover, raw garbage or organic waste contains a large amount of water. Due to the contained moisture, this raw garbage is not only heavy and difficult to handle, but also decays and becomes smelly after a long time, which pol...

Problems solved by technology

[0004] However, during the use of this drying device, the temperature rise of the condenser of the heat pump system will cause overheating, which may cause problems in the drying device. The system cannot supply enough heat into the drying unit, making proper drying difficult

[0005] In addition, when the drying device is operated, due to fluctuations in the amount of the object to be dried or the degree of dryness, etc., there may be a problem that the temperature of the evaporator drops below the freezing point and the water freezes.

At this time, the drying air cannot circulate smoothly, and the heat transfer efficiency is reduced due to the freezing of the heat exchanger surface, and the function of the drying device will be lost immediately.
