Title: Gas heat pump type refrigerating device
Inventor: ABE HIDEYO
IPC: F25B47/02
Filed: 1989-09-20
Abstract: PURPOSE:To increase room heating capacity and improve the performance coefficient of heating by a method wherein a bypass pipeline, whose one end is connected to a high-pressure liquid pipe of refrigerant and the other end is connected to a pipeline from a four-way valve to an indoor heat exchanger, is provided with a refrigerant pressurizing pump, an opening and closing valve and a heat exchanger for recovering waste heat. CONSTITUTION:In room heating mode, high-temperature high-pressure refrigerant gas from a compressor 1 enters into indoor side heat exchangers 9a-9c through a four-way valve 2 and solenoid valves 10a-10c and is condensed into liquid refrigerant, then, enters into an outdoor side heat exchanger 3 from non-return valves 12a-12c through solenoid valves 7a-7c, a receiver tank 5 and an expansion valve 13 for heating and is changed into gas refrigerant, then, is returned to and sucked into the compressor 1 through the four-way valve 2. On the other hand, one part of liquid refrigerant from the indoor side heat exchangers 9a-9c is pressurized by a refrigerant pressurizing pump 14 and becomes high-temperature high- pressure liquid refrigerant through heat exchange between the waste heat of cooling water of an engine in a waste gas auxiliary heat exchanger 20, then, is sent into the indoor side heat exchangers 9a-9c to effect heat exchange. The latent heat of condensation of the high- temperature high-pressure refrigerant gas is added with the sensible heat obtained through the heat exchange in the waste gas auxiliary heat exchanger 20 whereby room heating capacity may be increased.

Inventor: MOTOMURA MASAHIRO
IPC: H01L21/304
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To suppress the consumption of solvent and generation of particles. SOLUTION: Upon finishing pure water cleaning of a substrate in a processing bath 562, pure water DIW is supplied from a pure water supply 567c through piping 562e into the processing bath 562 and sustained at a constant temperature which is lower than a normal temperature by being cooled at a pure water temperature regulating section 567d. When a low-temperature substrate is pulled up from the processing bath 562, it is dried in an atmosphere containing IPA (isoproply alcohol) vapor of normal temperature at a high concentration, occupying the upper part of the processing bath 562. Since the temperature IPA vapor is not high, the quantity of IPA vapor being dissolved into pure water DIW in the processing bath 562 is reduced, while suppressing the generation of particles.
