DRIER COMBINED AIR CONDITIONING AND HEATING APPARATUS

摘要

The present invention relates to a dryer and cooling and heating apparatus, and more particularly, to a dryer and cooling and heating apparatus such as agricultural and aquatic products using a heat pump system. When drying, dehumidification is required when necessary to allow quick drying, refrigeration, and always hot water for hot water supply. The present invention is formed by partitioning the dry air generating chamber 12 on one inner side of the main body 11, the drying chamber 13 is formed on the other side of the dry air generating chamber 12 to put the dry tray 14 Drying chamber 10; The basic refrigeration cycle 21 is discharged from the compressor 22, the condenser 23, the four-way valve 24, the receiver 25, the first expansion valve 26, the outdoor heat exchanger 27 and the four-way The valve 24 is connected to the refrigerant conduit 28 in order, and the four-way valve 24 and the suction port of the compressor 22 are connected to the refrigerant suction conduit 29, and the receiver 25 and The second refrigerant conduit 31 is connected to the refrigerant suction conduit 29 to provide a second expansion valve 32 and an evaporator 33 in the second refrigerant conduit 31, and further to the refrigerant conduit 28. A first expansion conduit 34 is connected to the first bypass conduit 34 by connecting the first bypass conduit 34 to the inlet of the receiver 25 and the outlet of the four-way valve 24 in the drying mode. An indoor heat exchanger (36) is installed, and a second bypass conduit (37) for bypassing the condenser (23) is connected between the compressor (22) of the refrigerant conduit (28) and the four-way valve (23). The drying hole The evaporator 33, the circulating fan 38, and the condenser 24 in the air generating chamber 12, the outdoor heat exchanger 27 so as to be exposed to the atmosphere, and the indoor heat exchanger 36 in the cooling / heating place 51. It is comprised with the heat pump system 20 which installed).
