Abstract

PURPOSE: To improve the energy efficiency in the function selective cooler-heater type air conditioner, by controlling two two-way valves connecting the suction pipe with the discharge pipe of the compressor by the switch timer or the computer.
CONSTITUTION: The check valve 20 of the compressor 1 is connected with the suction pipe 11 through the valve 24, while it is connected with the discharge pipe 2 through the valve 23. The valves 23 and 24 are opened and closed by manual operation, or by means of programmed operation such as by the compressor switch (not shown), the timer (not shown) or the micro computer (not shown), or by the combination of these operations. Thus, the energy efficiency in the wide range from low to high loading can be improved, as well as the functions to cool and to heat are enabled to switch over to each other.
