摘要:
A refrigerating apparatus employs a mixture of coolants and a coolant controller for controlling a ratio between the coolants to adjust refrigerating capacity during a refrigerating operation. The apparatus has a compressor whose revolution speed is controlled to provide required refrigerating capacity. When the revolution speed of the compressor decreases below a lower set value or rises above an upper set value, the coolant controller controls the ratio between the coolants.

An air conditioning system in which each alternative refrigerant can be fully utilized so as to present as much as actual COP in comparison with the conventional HCFC22 and to achieve safe use as operating refrigerants. The air conditioning system includes: a first refrigerant circuit in which a first refrigerant circulates, the first refrigerant circuit including: an indoor heat exchanger; and a fluid drive unit, connected to the indoor heat exchanger by way of a first piping, which drives the first refrigerant; a second refrigerant circuit in which a second refrigerant circulates, the second refrigerant circuit including: a compressor which comparesses the second refrigerant; an expansion valve, connected to the compression means, for expanding the second refrigerant; and an outdoor heat exchanger connected to the compressor and the expansion valve by way of a second piping; and an intermediate heat exchanger for heat-exchanging between the first refrigerant in the first refrigerant circuit and the second refrigerant in the second refrigerant circuit.
摘要:
An air conditioner employs a refrigerating cycle in which a non-azeotropic mixture of high and low boiling coolants is sealed. The ratio between the high and low boiling coolants of the coolant mixture changes according to a change in the opening of an electric expansion valve 7. A level sensor 19 is arranged in an accumulator 17 that accumulates the liquid phase of the coolant mixture. A value detected by the level sensor is used to calculate the ratio between the high and low boiling coolants actually circulating in the refrigerating cycle. According to the opening of the valve 7 or the ratio between the actual quantities of the high and low boiling coolants, basic operation parameters such as the operation frequency of a compressor 1 are changed. This results in stabilizing and optimizing the operation of the refrigerating cycle even if a cycle temperature or pressure is changed due to a change in the ratio between the high and low boiling coolants of the coolant mixture.

An air conditioning system in accordance with the present invention is disclosed which has a radiation plate including a radiation surface facing a room area. A column of air that is either cooled or heated by a heat exchanger in an indoor unit of the present air conditioning system, is directed to flow along the radiation surface of the radiation plate. The room area is then either cooled or heated by radiant energy using the radiation properties of the radiation surface.
摘要:
Printed wiring boards (PWBs) applied to this inspection system are previously formed with marks in prescribed positional relation to wiring patterns. Deviation of PWBs with respect to absolute coordinates of the inspection system is detected by reading the marks. The PWBs are sequentially set one by one on a movable table, to be subjected to image acquisition of the marks and inspected areas. A first PWB is image-acquisited whereby obtained binary image data of the inspected area are stored in a memory unit. Thereafter a second PWB is image-acquisited, and in advance to the image acquisition of its inspected area, relative misregistration of the both PWBs is found by deviation data on respective marks of the first and second PWBs. The binary image data of the first PWB is read from the memory unit on the basis of the binary image data of the second PWB. When the binary image data of the first PWB are read, positional correction, i.e., time base correction is performed on the read data to correspond to pixels of the second PWB under image acquisition on the basis of data on the previously found amount of relative misregistration. The data on corresponding pixels of the both PWBs are compared with each other thereby to inspect difference between the patterns of the PWBs on the basis of the result of the comparison.
