Embodiment Construction

[0022] see figure 1 As shown, O represents the outdoor fan, and I represents the indoor fan. From figure 1 It can be seen from the figure that when the voltage of the existing fixed-frequency air conditioner is reduced, the speed of the outdoor fan is greatly reduced, but the speed of the indoor fan is not significantly reduced. The reduction of the speed of the outdoor fan leads to a reduction in the condensation capacity, while the evaporation capacity of the indoor fan does not decrease significantly, so the internal system of the fixed-frequency air conditioner is in an unbalanced state, and the compressor protector will operate to stop the compressor.

[0023] see figure 2 As shown, the fixed-frequency air conditioner of this embodiment includes a compressor 1, and the compressor 1 has an air inlet 18 and an air outlet 15; a condenser 2, and the condenser 2 has three inlets and three outlets; the compressor 1 The exhaust port 15 of the compressor 1 is connected to the...

Abstract

The invention provides an air-conditioner with a fixed frequency, comprising a compressor, a throttling device, an evaporator, a gas-liquid separator and a condenser, wherein, the compressor is provided with an air inlet and an air exhaust hole; the throttling device is provided with an inlet and an outlet, the evaporator is provided with an inlet and an outlet, and the inlet of the evaporator is connected with the outlet of the throttling device; the gas-liquid separator is provided with an air sucking hole and an air outlet, the air sucking hole of the gas-liquid separator is connected with the outlet of the evaporator, and the air outlet of the gas-liquid separator is connected with the air inlet of the compressor; and the condenser is provided with at least two inlets and at least two outlets, the inlets of the condenser are connected with the air exhaust hole of the compressor, and the outlets of the condenser are connected with the throttling device. The air-conditioner with a fixed frequency provided by the invention has a wide operation voltage range, can operate at a low voltage, and is especially applicable to the regions with unstable voltages.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a fixed-frequency air conditioner. Background technique [0002] The operating voltage of the existing fixed-frequency air conditioner is 198-242V, and the starting voltage of the compressor is 176V, so the voltage range of the fixed-frequency air conditioner during normal operation is 176-242V. In the process of voltage reduction of the fixed-frequency air conditioner, the current value keeps increasing. When the voltage drops below 187V, the current fluctuates frequently and often rises abnormally. At this time, the compressor protector will act to stop the compressor. Therefore, in areas with insufficient power supply, the voltage may be lower than 176V, and the existing fixed-frequency air conditioner compressor cannot be started at all. In areas with unstable voltage, due to large voltage fluctuations, the internal system pressure fluctuations of existing fixed-frequency air...
