Abstract: PURPOSE:To control almost all of foods in a kitchen in the optimum circumstance through central control at one place by a method wherein the title shed is divided into a freezing chamber, a refrigerating chamber, a middle temperature chamber and the like and is provided with a common refrigerating cycle as well as damper thermostats, operated within the set range of temperatures different from each other. CONSTITUTION:Air, cooled by a cooler 19, is circulated forcibly by a fan 20 into a freezing chamber 5 through the discharging port 27 of the freezing chamber to cool the chamber 5 to about -18 deg.C, then, is returned to the cooler 19 through the suction port 28 of the same chamber and, thereafter, is circulated into a refrigerating chamber 6 through an air passage 21 for sending the air into the refrigerating chamber, a first damper thermostat 24a and the discharging port 22 of the refrigerating chamber to cool the same chamber 6 to the temperature of about 1-5 deg.C, then, is returned to the cooler 19 through the returning air passage of the refrigerating chamber and, thereafter, is circulated into a middle temperature chamber 7 through an air passage 23 for discharging air into the middle temperature chamber, a second damper thermostat 24b and the discharging port 26 of the middle temperature chamber to cool the same chamber 7 to the temperature of about 10-15 deg.C, then, the air is returned to the cooler 19 through the returning air passage 29 of the middle temperature chamber. When the environmental room temperatures of the main body 1 of a storage shed are lower than the target temperature range (10-15 deg.C) of the middle temperature chamber 7, a heater for compensating low-temperature atmosphere is excited to supply heat into the middle temperature chamber 7. The low-temperature atmosphere compensating heater 30 can be an apparatus utilizing the waste heat of the heat exchanger of the refrigerating cycle except a heat generating resistance.

Abstract: PURPOSE:To prevent the deterioration of foodstuffs or the like by forming a first, second, and third storage chambers with an insulated box from the top, installing a storage vessel equipped with a cover comprising a moisture permeability film in the second storage chamber, and controlling the reference temperature range of each storage chamber so that the tempera ture range may be switched over to middle temperature and cold storage. CONSTITUTION:The air cooled by a cooler 19 is circulated through each storage chamber 8, 9, and 10 by driving a blower 20 and the temperature in each storage chamber is controlled and switched over to middle temperature (about 10 to 18 deg.C) and cold storage (about 1 to 8 deg.C) by a controller 21 and a manipulator 26, thereby maintaining a proper temperature. Furthermore, it is possible to maintain a proper temperature range (about RH30 to 50%) by the dehumidification and humidification actions of the cooler 19 driven by the on/off operation of a compressor 18. During the maintenance of the middle temperature, the tempera ture difference between the open air and the in-chamber temperature is smaller than that during cold storage maintenance, which makes it possible to inhibit bedewing generated when taking out dried goods which hate moisture. Furthermore, a storage container in the second storage chamber 9 self controls the water vapor generated by transpiration or breathing action of vegetables stored with a moisture permeability film of a cover so that drying may be prevented.

Abstract: PURPOSE:To improve an evaporating capability to make a better convection and to prevent mists from being generated and to reduce noise by a method wherein an interior part of a machine chamber is communicated without separating by a holding element, radiator plates are arranged and fixed at an upper zig-zag part and a lower zig-zag part of a high temperature pipe under a heat exchanging relation and they are held without being abutted against an evaporation pan. CONSTITUTION:Since a machine chamber 3 is not divided by a holding element 10, evaporated moisture can be concurrently moved when cold air is convected to a side heated by an electrical compressor 6, resulting in that no dew adheres to a ceiling of the machine chamber. Since a high temperature pipe 9 is not contacted with an evaporation pan 8, vibration of the electrical compressor 5 is not transmitted, so it does not become a source of noise. Radiation plates 21 and 22 are arranged and fixed at an upper surface and a lower surface of a zig-zag part 9a of a high pressure pipe 9 under a heat exchanging relation, it is possible to improve a radiation capability and improve a defrosted water evaporating capability and at the same time it is also possible to make a substantial reduction of vibration and resonance of the high pressure pipe caused by a pulsation of the refrigerant discharging pressure to be transmitted from the compressor 5 to the high pressure pipe 9.

Abstract: PURPOSE:To prevent the deterioration in foodstuffs and lingering odor by forming a first, second, and third storage chambers, installing a storage vessel equipped with a cover made of a moisture permeability film in the second storage chamber, a dried goods chamber in the first storage chamber, and switching over each storage chamber to middle temperature and cold storage under control. CONSTITUTION:The air cooled with a cooler 19 is circulated through each storage chamber 8, 9, and 10 by a fan 20 where a switch over controller 21 controls the temperature in each storage chamber so that it may be switched over to middle temperature (about 10 to 18 deg.C) and old temperature (about 1 to 8 deg.C), thereby maintaing the temperature. A humidification action and dehumidification action of the cooler 19 based on its on/off operation maintains the temperature of dried goods at a proper value (about RH 30 to 50%), thereby minimizing the temperatur difference between the open air and the chamber when it is maintained at the middle temperature (about 10 to 18 deg.C) and hence inhibits bedewing when an attempt is made to take out dried goods which hate moisture. Furthermore, a door, which can be freely opened, is provided in a drying chamber 27 is installed to the first storage chamber 8, which can prevent lingering odor. A storage vessel 11 installed in the second storage cham ber 9 self controls the water vapor generated by the transpiration or breathing action of vegetables and fruit to be stored in a storage vessel 11 in the second storage chamber 9 with a moisture permeability film of a cover so that drying may be prevented.

Abstract: PURPOSE:To prevent the oxidation of foodstuff, loss in vitamin C, moisture absorption, and deterioration in flavor by installing a controller which switches over a reference temperature range of each storage chamber under control, a drying chamber provided in a first storage chamber, and a deodorization unit provided in a cooled air circulation duct. CONSTITUTION:When a thermostat 21 is set to a middle temperature with a thermo dial 26, a compressor 18 and a blower 20 are placed under on/off control so that a first, a second, and third storage chambers 8, 9, and 10 may be kept at a middle temperature (ranging from about 10 to 18 deg.C). At the same time, they are kept at a humidity proper to dry goods (about RH30 to 50%) by the humidification and dehu midification actions of a cooler 19 while stored foodstuff is kept from the loss in vitamin C and the deterioration in their flavor so that they may be preserved for a long time. Moreover, when they are set to cold storage, each storage chamber is kept in cold storage mode (about 1 to 8 deg.C) and maintained at a proper humidity as well, which prevents excessive drying for cold storage foodstuffs and improves the maintenance of foodstuffs. Furthermore, when power is case, power is supplied to a high voltage generation unit 34 for a deodorization unit 31, an ozone generator 35, and a deodorization blower 37 at the same time. A catalyst 36 make it possible to eliminate the odor of dried goods or the like in a drying chamber 27.
