Abstract
Abstract A cooling system includes a circuit for the adjusting of the capacity of a compressor of a refrigeration cycle, and a circuit for stopping a blower until an evaporator of the refrigeration cycle is substantially dewed after the starting of the compressor and a circuit for driving the compressor at the maximum capacity until the blower has begun to be driven. The evaporator is cooled quickly because the compressor is driven at its maximum capacity, so that the time of the stoppage of the blower can be short while preventing a bad odor from circulating.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
138 words
A cooling system including a refrigeration cycle having a compressor and an evaporator, and a blower for supplying air to said evaporator of said refrigeration cycle, comprising: (a) a means for adjusting for the capacity of said compressor, said compressor having a maximum capacity and a lower normal capacity; (b) a means for stopping said blower until said evaporator is substantially dewed after the start of said compressor; (c) a means for driving the compressor to maximize the capacity of said compressor under the action of said capacity adjusting means until the stoppage of said blower is nullified under the action of said blower stopping means; and (d) a synchronizing means for synchronizing the starting of said blower with the changing of said compressor capacity by said capacity adjusting means from its maximum capacity to its normal capacity.
Claim 2
Dependent Claim
138 words
A cooling system including a refrigeration cycle having a compressor and an evaporator, and a blower for supplying air to said evaporator of said refrigeration cycle, comprising: (a) a means for adjusting for the capacity of said compressor, said compressor having a maximum capacity and a lower normal capacity; (b) a means for stopping said blower until said evaporator is substantially dewed after the start of said compressor; (c) a means for driving the compressor to maximize the capacity of said compressor under the action of said capacity adjusting means until the stoppage of said blower is nullified under the action of said blower stopping means; and (d) a synchronizing means for synchronizing the starting of said blower with the changing of said compressor capacity by said capacity adjusting means from its maximum capacity to its normal capacity.
Claim 3
Dependent Claim
18 words
A cooling system according to claim 1, wherein said capacity adjusting means adjusts the r.p.m. of said compressor.
Claim 4
Dependent Claim
19 words
A cooling system according to claim 1, wherein said capacity adjusting means adjusts the discharge volume of said compressor.
Claim 5
Dependent Claim
19 words
A cooling system according to claim 1, wherein a manual switch is provided for manually nullifying said synchronizing means.
