Problems solved by technology

[0002] At present, split floor-standing air conditioners are commonly used in the market. However, two temperature sensors, an outdoor ambient temperature sensor and an outdoor heat exchanger temperature sensor, are generally installed on the outdoor heat exchanger. Among them, the outdoor ambient temperature sensor is installed on the Next to the outdoor heat exchanger, it is used to detect the outdoor ambient temperature. The air conditioner can judge whether the outdoor ambient temperature is too high or too low according to the outdoor ambient temperature, estimate the pressure of the air conditioning system, and judge whether to perform frequency limit or shutdown protection to ensure that the air conditioner The system is safe in operation and is also used to control the speed of the outdoor fan. The outdoor coil temperature sensor is installed on the outdoor heat exchanger to detect the coil temperature of the outdoor heat exchanger and to judge whether the outdoor unit needs defrosting and When it is judged that the temperature is too high or too low, the frequency limit or shutdown protection is performed to protect the system; in addition, the compressor of the split floor air conditioner is generally installed in the outdoor unit, so the cost of the air conditioner is high, and it is placed outdoor The machine is easily damaged, and because the compressor is relatively heavy, the outdoor unit will also be relatively heavy, which makes the installation of the outdoor unit very inconvenient, requires more people to install, and requires higher installation costs

Abstract

The invention provides a split floor type air conditioner which comprises an indoor unit, an outdoor unit and a temperature detection device. The indoor unit is provided with an indoor heat exchanger, a throttling device, a compressor and an indoor fan. The outdoor unit is provided with an outdoor heat exchanger and an outdoor fan. The indoor heat exchanger, the throttling device, the outdoor heat exchanger and the compressor are circularly communicated through connection pipelines to form a refrigeration loop. The temperature detection device is arranged on the connection pipeline between the throttling device and the outdoor heat exchanger, electrically connected with a master control circuit board and used for detecting the temperature of a coiled pipe of the outdoor heat exchanger. The master control circuit board controls the running states of the compressor, the indoor fan and the outdoor fan according to the temperature of the coiled pipe of the outdoor heat exchanger and / or the outdoor environment temperature of the outdoor unit. The outdoor environment temperature is obtained by calculation according to the temperature of the coiled pipe of the outdoor heat exchanger. According to the technical scheme, the production cost is decreased while the placement stability of the indoor unit is improved, the outdoor environment temperature is obtained through calculation of the temperature of the coiled pipe of the outdoor heat exchanger, and then the running state of the air conditioner is controlled.
