空気調和装置
Document Type and Number:
Japanese Patent JP6834616
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an air conditioner capable of preventing a discharge temperature from abruptly rising after end of temperature protective control.SOLUTION: In target discharge temperature control, a CPU obtains target opening Dt based on the temperature difference between a discharge temperature Td and a target discharge temperature Tdt. Then, the CPU determines whether control of a compressor is temperature protective control. When the control of the compressor is the temperature protective control, that is, when the temperature protective control and the target discharge temperature control are executed concurrently, the CPU defines a value obtained by adding adjustment opening Da to the target opening Dt, as the target opening Dt. When the control of the compressor is not the temperature protective control, that is, when normal control and the target discharge temperature control are executed concurrently, the CPU never changes the target opening Dt. Then, the CPU adjusts expansion valve opening D to the target opening Dt.SELECTED DRAWING: Figure 4
