REFRIGERATING CYCLE APPARATUS

摘要

A refrigerating cycle apparatus includes an evaporator, a compressor, a condenser, a feeding channel, a main circuit that circulates a refrigerant including fluid whose saturated vapor pressure at ordinary temperature is a negative pressure as a main component, a heat absorption circuit including a heat absorption heat exchanger, a heat release circuit including a heat release heat exchanger, an internal heat exchanger that allows indirect heat exchange between the fluid flowing through the heat absorption circuit and the fluid flowing through the heat release circuit, at least one of a heat absorption bypass channel and a heat release bypass channel, and at least one of a flow rate adjustment mechanism for heat absorption that adjusts a flow rate of the fluid flowing through the heat absorption bypass channel and a flow rate adjustment mechanism for heat release that adjusts a flow rate of the fluid flowing through the heat release bypass channel.

1. A refrigerating cycle apparatus comprising:
a first circuit that circulates a refrigerant flowing therein; a second circuit that circulates the refrigerant flowing therein; a third circuit that circulates the refrigerant flowing therein; an evaporator that is commonly disposed on the first circuit and the second circuit, that stores the refrigerant in liquid form, and that evaporates the refrigerant; a compressor that compresses the evaporated refrigerant; a condenser that is commonly disposed on the first circuit and the third circuit, that stores the refrigerant in liquid form, and that condenses the compressed refrigerant; a first heat exchanger that is disposed on the second circuit and that heats the refrigerant; a first pump that is disposed on the second circuit and that circulates the refrigerant; a second heat exchanger that is disposed on the third circuit and that cools the refrigerant; a second pump that is disposed on the third circuit and that circulates the refrigerant, wherein the refrigerant's saturated vapor pressure at ordinary temperature is a negative pressure, the second circuit comprises a first portion and a second portion, the second portion being positioned between the first portion and a portion where the refrigerant flows into the evaporator, the third circuit comprises a third portion and a fourth portion, the fourth portion being positioned between the third portion and a portion where the refrigerant flows into the condenser, the refrigerating cycle apparatus further comprises at least one selected from the group of: a first bypass channel that connects the first portion to the second portion, in the first bypass channel the refrigerant flowing from the first portion to the second portion; and a second bypass channel that connects the third portion to the fourth portion, in the second bypass channel the refrigerant flowing from the third portion to the fourth portion, a third heat exchanger that is sharedly disposed
on the first bypass channel and the third circuit,on the second circuit and the second bypass channel, oron the first bypass channel and the second bypass channel, the refrigerant cycle apparatus further comprises at least one selected from the group of: a first adjustment mechanism that adjusts a ratio of an amount of the refrigerant flowing in the first bypass channel to an amount of the refrigerant flowing from the first portion to the second portion in the second circuit; and a second adjustment mechanism that adjusts a ratio of an amount of the refrigerant flowing in the second bypass channel to an amount of the refrigerant flowing from the third portion to the fourth portion in the third circuit.
