Abstract

PURPOSE:To make it possible to prevent fall in temperature during defrosting operation without using a complicated construction of this device by providing a room temperature sensor and a defrosting condition sensor, starting the defrosting operation when they are detected and the room temperature reaches a set temperature, measuring and storing in a memory room temperature drop during defrosting operation, and raising said set temperature by the drop in temperature which is stored in the previous operation before starting next defrosting operation. CONSTITUTION:A defrosting condition sensor 10 and a room temperature sensor 17 which detects room temperature are provided. When an output of the defrosting condition sensor 10 is inputted, a set temperature for the room temperature sensor 17 is raised by a set temperature raising means 18. When it is detected by defrosting operation means 19 that a room temperature detected by the room temperature sensor 17 has reached a set temperature which is set up by a set temperature raising means 18, a four-way valve 2 is changed over through a change-over opening and closing device 11 to conduct defrosting operation, and at the same time drop in the room temperature during defrosting operation is measured and stored in memory by a room temperature drop memory device 20 and the memory is outputted to the set temperature raising means 18 to set up a set temperature for next operation.

During heating operation, when the heating switch 0τ is closed, the drive coil (2A) is energized and the four-way valve (2) is set to the heating cycle side. As a result, the high-temperature, high-pressure gas discharged from the compressor (1) flows as shown by the arrow, passes through the four-way valve (2), is forced into the indoor heat exchanger (3), and is forcedly ventilated by the indoor fan (8). As a result, warm air is blown into the room. On the other hand, the gas refrigerant cooled by the forced draft becomes a condensed liquid, expands adiabatically in the pressure reducing device (4), and becomes a low-pressure refrigerant. and,
It is heated in the outdoor heat exchanger (5) by the forced ventilation of the outdoor fan (9), evaporates, becomes low-pressure gas, passes through the four-way valve (2), and is sucked into the compressor (11). As the temperature increases, the amount of heat sucked up from the outdoor heat exchanger (5) to the refrigerant circuit (power) decreases, and when the evaporation temperature decreases to below the zero point temperature, frost begins to form on the outdoor heat exchanger (5). As a result, the ability to absorb heat decreases, and the input pipe temperature of the outdoor heat exchanger (5) further decreases.When the temperature drops below a predetermined temperature, the defrosting condition detector OQ outputs an output.This output causes the switching device αυ Since the contact (11a) is opened, the drive coil (2A) is deenergized and the four-way valve (2A) is deenergized.
) is switched, the flow direction of the refrigerant becomes opposite to the arrow, and the refrigerant circuit (7) enters cooling operation. Contact (11
Contact (11b) closes at the same time as relay a) opens, and relay a
2 is energized and the contact (12a) is opened, so the indoor fan (8) stops blowing air. This prevents cold air from being blown to the occupants. In this way, the four-way valve (2) is switched and the cooling operation is started, so that the compressor (1)
The high-temperature, high-pressure refrigerant gas discharged from the refrigerant passes through the four-way valve (2) and then enters the outdoor heat exchanger (5), where the frost adhering thereto is melted by the heat of the refrigerant. This is the defrosting operation.
