Title: Refrigerant evaporator
Inventor: AIKAWA TAIICHI
IPC: F25B31/00
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To permit the shortening of the starting time of liquid refrigerant returning to a compressor immediately after starting a cycle under a low thermal load condition in winter by a method wherein a bypass route, bypassing at least one set of a plurality of heat exchanging units with a sufficiently small passage area compared with that of a refrigerant passage, is accommodated in an evaporator. SOLUTION: Six kinds of bypass routes BP1-BP6, bypassing heat exchanging units 1-4, are provided and a part of refrigerant, flowing into an evaporator 1, flows through either one of a plurality of heat exchanging units 1-4 or flows a plurality of heat exchanging units while bypassing by setting either one set of the bypass route or a plurality of pieces of bypass routes BP1-BP6 under a combined condition. The bypass refrigerant is not effecting heat exchange in the heat exchanging units 1-4 whereby the bypass refrigerant flows without being evaporated substantially. According to this method, the amount of returning oil into the compressor can be increased into a good condition within a short period of time after starting the cycle under a low thermal load condition in winter whereby the insufficient lubrication of the compressor can be reduced.

IPC: H04L12/00
Filed: 1990-05-28
Abstract: PURPOSE:To correct a time of a hardware clock accurately in a subsystem even when inter-system communication is in congestion by sending a time notice request, receiving time notice information of a main system and adding a calculated delay time to correct the time of the hardware clock. CONSTITUTION:A delay time calculation means 5 of a subsystem 3 measures a time from a transmission time t1 of a time notice request to a reception time t3 of time notice information based on the time of a hardware clock 4, uses a delay coefficient as (k), measures a time t2 of the clock of a hardware clock 2 of a main system 1, that is, t2=t3-(t3-t1)/k and obtains a delay time (a) as (t3-t2). Then a time correction means 6 adds the calculated delay time (a) to a time of time notice information from the main system 1 as a current time to correct the time of the hardware clock 4. Thus, even when the inter- system communication is in congestion, the time of the hardware clock 4 in the subsystem 3 is accurately corrected.
