Title:
MULTI-CHAMBER SPLIT TYPE HEATER
Document Type and Number:
Japanese Patent JPH08145482
Kind Code:
A
Abstract:

PURPOSE: To safely continue the operation by preventing the stop of an equipment due to the overcurrent at the time of heating at a low load in a refrigerating cycle using a non-azeotrope refrigerant.

CONSTITUTION: The multi-chamber split type heater comprises temperature sensors 10a, 10b for detecting an indoor side heat exchanger outlet temperatures, a discharge pressure sensor 18, a current sensor 19, temperature difference calculating means 26a, 26b for calculating the temperature difference between the saturated gas temperature calculated from the discharge pressure and the temperatures from temperature sensors 10a, 10b, target temperature different calculating means 28a, 28b for calculating target temperature difference based on the output current value of a compressor 1, and indoor side expansion valve operating means 30a, 30b for so controlling to switch indoor side expansion valves 8a, 8b as to arrive at the target temperature difference.
