The invention discloses a heat pump cold-end heat radiation type sealed dehumidification drying house which comprises a drying room, a dehumidification return heat room and a heating room, wherein the air inlet side of the dehumidification return heat room is connected with the drying room, the air outlet side of the dehumidification return heat room is connected with the heating room, and the air outlet side of the heating room is connected with the drying room. A dehumidification coil located on the air inlet side of the dehumidification return heat room and a heat recovery coil located on the air outlet side of the dehumidification return heat room are built in the dehumidification return heat room, the dehumidification coil is in series connection with a refrigerant pipeline of the heat recovery coil, the outlet end of the dehumidification coil in series connection with the refrigerant pipeline of the heat recovery coil is further connected with an outward radiator, and a flow controller is arranged in a heat pump cold water circulating pipeline. The drying house achieves the outward natural heat radiation effect through matching of the dehumidification coil and the heat recovery coil in the dehumidification return heat room, matching of the radiator and a hot air coil and a refrigerant at a heat pump cold-end dehumidification section and accordingly achieves energy saving.
Description
technical field [0001] The invention relates to the fields of energy-saving refrigeration technology and heat energy technology, in particular to a sealed drying room which utilizes a heat pump combined cooling and heating for dehumidification and heating. Background technique [0002] Heat pumps are favored by the public for their zero emissions, high energy efficiency, safety and reliability, and convenient operation. Especially in high-energy-consuming industries represented by the drying industry, heat pumps have been widely used. Based on the characteristics of simultaneous heating and cooling, heat pumps are very It is suitable for air heating and condensation dehumidification in sealed drying rooms. The sealed drying room condenses the indoor water vapor and discharges it. There is no fresh air in the material drying process, avoiding the inhalation of cold wind, moisture, dust and insects, and at the same time reducing the loss of material odor , The sealed drying ro...
