Abstract: This disclosure is related to an air conditioning and ventilating device. An air conditioning unit, a first ventilation fan set, an inner air-conditioning fan and an outer air-conditioning fan are disposed in a cabinet. The cabinet includes a cabinet body and a partition. The cabinet body is separated into an inner chamber and an outer chamber. The cabinet body includes an inner ventilation inlet, an inner air-conditioning inlet, an inner air-conditioning outlet and an inner ventilation outlet communicating with the inner chamber. The cabinet body includes an outer air outlet and an outer air-conditioning inlet communicating with the outer chamber. The first ventilation fan set communicates with the inner ventilation inlet and the outer air outlet. The inner air-conditioning fan communicates with the inner air-conditioning inlet and the inner air-conditioning outlet. The outer air-conditioning fan communicates with the outer air-conditioning inlet and the outer air outlet.

Abstract: A detection method for an air-conditioning system includes detecting whether the input power of the compressor of the air-conditioning system is lower than the power threshold. The method includes obtaining the evaporation saturation temperature of the evaporator of the air-conditioning system and obtaining the condensation saturation temperature of the condenser of the air-conditioning system when the input power is lower than the power threshold. When detecting that the evaporation saturation temperature is greater than the condensation saturation temperature, the method includes determining that an abnormal phase change is occurring and operating the compressor in the full-speed mode.

Abstract: An air conditioning system includes a control unit, a circulation system, an AC-to-DC conversion unit, and a fan module. The control unit detects an area temperature, controls the compressor unit being in operation or not in operation according to the area temperature and a setting temperature set by the control unit, and control a rotation speed of the condensing fan according to a temperature difference between the area temperature and the setting temperature. When the area temperature is greater than the setting temperature, the control unit controls the compressor unit being in operation and control the condensing fan being in full-speed operation.

Abstract: A temperature-regulated cabinet (10) includes a cabinet body (1) and a temperature regulating module (2). The cabinet body (1) has a containing space (11) formed inside the cabinet body (1) and an opening (12) communicated with the containing space (11). The temperature regulating module (2) is detachably installed to the cabinet body (1) and covered onto the opening (12) and includes a temperature regulator (21), a first hood (22), a second hood (23) and an exhaust fan (24). The temperature regulator (21) has a casing (211). The first hood (22) is detachably installed to the top of the casing (211), and the second hood (23) is detachably installed to the bottom of the casing (211). The exhaust fan (24) is installed inside the first hood (22) or the second hood (23). The cabinet has the advantages of simplifying the production line and lowering the construction and operation costs.

Abstract: An air conditioner is provided that includes an outer circulation unit. The outer circulation unit includes an outer circulation housing, an outer circulation inlet, an outer circulation outlet, and a condenser. The outer circulation inlet is formed on the outer circulation housing. The outer circulation outlet is formed on the outer circulation housing. An outer circulation flow enters the outer circulation unit via the outer circulation inlet, passes through the condenser to remove heat from the condenser, and leaves the outer circulation unit via the outer circulation outlet, wherein the height of the outer circulation inlet is higher than the height of the outer circulation outlet in a vertical direction.
