Title:
REFRIGERANT HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/091566
Kind Code:
A1
Abstract:
A refrigerant heating device with which super heat of a refrigerant is effectively
suppressed and that can control the temperature of the refrigerant by itself
without relying on an external temperature sensor. The refrigerant heating
device (4) has at least one connection tube (11, 16), a heater (12), and at least
one temperature sensor (13, 14, 15). The at least one connection tube (11, 16)
is connected to the middle of a refrigerant circuit (10). The refrigerant circulates
in the refrigerant circuit (10). The heater (12) heats the refrigerant flowing
in the first connection tube (11) out of the connection tubes. The at least one
temperature sensor (13, 14, 15) detects the temperature of the refrigerant flowing
in the connection tube.
