摘要： PROBLEM TO BE SOLVED: To solve problems in the conventional art in which an apparatus for freezing/refrigerating foods and an air conditioner for the inside of a shop are separately controlled, and a collection of heat from heat dispersion from a condenser of the chiller is not conducted for a heat absorption operation of an outdoor heat exchanger of the air conditioner in the winter period. SOLUTION: The heat of a condenser in a chiller is transferred to the outdoor heat-exchanger of the air conditioner, and is collected by conducting a heat- transfer between the condenser in a chiller heat-source cycle and the heat- exchanger in the air-conditioner heat-source cycle or by making a draft serially to them. Further, indoor air is sent to a condenser of a chiller to collect waste heat in the summer period.

摘要： PROBLEM TO BE SOLVED: To discharge a negative ion into specific space while suppressing the speed of an air current by providing the specific space where an object is arranged and a wall surface is grounded, and a negative ion generator that generates the negative ion and sends it into the specific space. SOLUTION: At the temperature and relative humidity of a temperature/humidity adjustment room 4 of a refrigerating machine 1, the wind velocity of air containing a negative ion being discharged via an outlet 14 by a fan is adjusted while the amount of wind from the refrigerating machine 1 is being considered so that a specified speed of an air current is set for an object 3 to be sterilized. Since an external wall 5, the refrigerating machine 1, and a negative ion generator 2 are insulated, and a voltage is applied to an attraction member 10, the extent of the negative ion in the temperature/humidity adjustment room 4 in an electromagnetic field is extended by allowing the negative ion to flow from the outlet of the negative ion generator 2 to the attraction member 10 via the outlet 14, thus uniformly distributing the concentration of the negative ion between the negative ion generator 2 and the attraction member 10.

摘要： PROBLEM TO BE SOLVED: To make the stabilization of size promotable owing to the smoothenization of both surfaces ans also a firm laminate conjunction promotable by means of a wedging action as well, as urethane foam is formable into lamination lying between both pinched surfaces and both sides of a styrol foam plate, and at that time this urethane foam is able to get into uneven both sides on the styrol foam plate. SOLUTION: After a styrol foam plate 12 is pinched between both first and second fiber reinforced plastic plates 10 and 11, a urethane foam liquid 13 stuck to both pinched surfaces 10a and 11a is foamed up, and urethan foam is formed into lamination lying between both these pinched surfaces 10a and 11a and both sides of styrol foam plate 12. This urethan foam gets into uneven both sides in the styrol foam plate 12, and thereby the stabilization of size is promoted by the smoothenization of both sides, and also a firm laminate conjunction is promoted by a wedging action. Thus, a laminated panelboard 16, which is sufficient enough in adiabatic effect and inexpensive in cost, is securable.

摘要： PURPOSE:To prevent frozen food from melting due to a rise in the temperature on a refrigeration side by hindering the supply of refrigerant to a cold storage side evaporator when a lower stage side compressor is suspended by a protection device of the lower stage side compressor in terms of a two stage type refrigerating platnt provided with a cold storage evaporator and a refrigeration evaporator. CONSTITUTION:The gas refrigeratnt from a higher stage side compressor 1 is condensed by a condenser 2 and pressure-reduced by each of throttling devices 4 and 8 and then evaporated by evaporators 5 and 9 housed in each show case for cold storage and for refrigeration. The refrigerant which has left the second evaporator 9 is sucked up into the higher stage side comprssor 1 by way of a lower stage compressor 10. In this case, the lower stage side compressor 10 is suspended by a protection device 15 when a detected value of motor current reaches an abnormal value. There are also installed each of controllers 13 and 14 which close each of solenoid valves 3 and 7 when the ambient temperature around the evaporators 5 and 9 fails to exceed a specified value. The contacts 13a and 15a for the controller 13 and the protection device 15 are connected with a coil 13a of a solenoid value 13 in serial and the solenoid valve 13 is closed by the output of the controller 13 and the protection device.

摘要： PURPOSE:To prevent frozen food from melting due to a rise in the temperature of a show case by lowering operaion control values of a higher stage side compressor with the output of a protection device of a lower stage side comressor in terms of a two stage type refrigerating plat having a cold storage evaporator and a refrigeration evaporator. CONSTITUTION:The gas refrigerant from two higher stage side compressors 1 is condensed by a condenser 2 and pressure-reduced by each of throttling devices 4 and 8 and then evaporated by evaporators 5 and 9 housed in each cold storage show case and each refrigeration show case. The refrigerant which has left the second evaporator 9 is sucked up into a higher stage side compressor 1 by way of a lower stage side compressor 10. The lower stage side compressor 10 is suspended by a protection device 15 when a detected value of motor current reaches an abnormal value. The high stage side compressor 1 is controlled by an operation control device 14 in such a fashion that the number of actually operated compressors 1 are determined according to the result of comparison between the pressure value detected by a detector 13 and the preset value. The preset value of the operation control device is shifted to a lower value by a specified value by a set value changing means 16 which receives the output of the protection device 15.

摘要： PURPOSE:To perform defrosting in a constantly proper frosting state regardless of the surrounding conditions of a vaporizer and a condenser by a method wherein a vaporizing temperature after the lapse of a given time starting from the starting of operation is stored, and based on a difference between the stored temperature and a present vaporizing temperature, a defrosting signal is outputted. CONSTITUTION:After a high temperature high pressure gas refrigerant delivered from a compressor 11 is condensed by a condenser 12, the refrigerant is reduced in a pressure by a throttle device 13 and flows to a vaporizer 14. In which case, the refrigerant is vaporized as it cools inflow air, and is returned to the compressor 11. During continuance of cooling operation in a manner described above, formation of frost is progressed at the vaporizer 14. Thereby, the heat exchange efficiency of the vaporizer 14 is lowered and a vaporizing temperature is decreased. After the lapse of a given time starting from the starting of operation, i.e., at a point of time T1, a difference between temperature stored in a memory device and a present vaporizing temperature detected by a temperature detector is increased. When the difference is increased to a given value, an output device is operated, and an output is generated from a defrosting device.

摘要： PURPOSE:To enable always maintaining of a proper dehumidifying capability by a method wherein a condenser and an evaporator are selected for a second heat exchanger in response to a flowing air temperature. CONSTITUTION:When a flowing air temperature is higher than the desired temperature, this condition is sensed by the sensor 11, the first opening or closing valve 7a is closed and the second opening or closing valve 9b is opened. As a result, the coolant discharged from the compressor 1 is flowed as indicated by a rigid arrow line, condensed at the first heat exchanger 6, thereafter its pressure is decreased through the first metering device 7b, a part of the coolant is evaporated through the second heat exchanger, it is passed through the second opening or closing valve 9a and the remaining liquid coolant is evaporated at the third heat exchanger 10. Then, the coolant is returned back again to the compressor 1. When the temperature is less than the desired temperature, the coolant is flowed as indicated by a broken line arrow, a part of the coolant is condensed by the first heat exchanger 6, thereafter it is passed through the first opening or closing valve 7a, reaching the second heat exchanger 8 and there the remaining coolant is condensed. The liquified coolant is decreased in its pressure at the second metering device 9b, evaporated by the third heat exchanger 10 and then it is returned back to the compressor 1.
