A heat pump circuit for an edible fungus drying device

Abstract

The invention discloses a heat pump loop for an edible fungus drying device. The heat pump loop comprises a condenser and three groups of compressor and evaporator assemblies which are arranged in parallel, wherein each group of compressor and evaporator assembly comprises an expansion valve, an evaporator and a compressor which are connected in sequence; the condenser comprises a gas collecting mixing device, a snake-shaped tube bundle and a liquid collecting mixing device which are connected in sequence; the gas collecting mixing device comprises a gas colleting inner tube and a gas colleting outer tube sleeved outside the gas collecting inner tube; a gap between the gas colleting inner tube and the gas colleting outer tube is a gas collecting static layer; the liquid collecting mixing device comprises a liquid collecting inner tube and a liquid collecting outer tube sleeved outside the liquid collecting inner tube; and a gap between the liquid collecting inner tube and the liquid collecting outer tube is a liquid collecting static layer. Based on energy exchange realized by the existing condenser only, the working medium exchange is realized, the utilization efficiency of the condenser is improved, the heat exchange efficiency is improved, uneven thermal power between refrigeration working media caused by uneven treatment is reduced, the output range and handling capacity of an air handling unit are improved, and the uniformity of air handling is improved.

Description

technical field [0001] The invention relates to the technical field of equipment related to air conditioning units, in particular to a heat pump circuit for an edible fungus drying device. Background technique [0002] Drying storage is an effective storage method commonly used for agricultural products with high water content, and the baking room is a commonly used equipment for mass production. When drying, the moisture evaporates from the agricultural products into the surrounding air, which increases the humidity of the air and decreases the temperature. As the core equipment of the baking room, the air handling unit plays the role of dehumidification and heating. At present, most of the baking rooms in rural areas are hot air convection drying rooms heated by flue gas. This traditional type of baking room has simple equipment and low initial investment, but it has low baking efficiency and poor quality of dried food. Poor, environmental pollution and a series of probl...
