In addition, if countermeasures against the temperature rise of the motor are taken, there will be a problem of increasing the size of the motor, which leads to an increase in cost.
[0005] In addition, a device that detects the temperature near the oxygen-enriched membrane and continuously controls the amount of pump operation by means of an inverter has also been considered. However, such a so-called constant-speed air conditioner can only move from the indoor unit to the outdoor unit. Sending a power connection or disconnection signal, there is no device that detects the temperature on the outdoor unit side, and the above-mentioned countermeasures are difficult to implement

Embodiment 1
[0020] First, use Figure 1 ~ Figure 2 Example 1 will be described.
[0021] figure 1 is a schematic cross-sectional view of the outdoor unit of the air conditioner of the present invention, figure 2 It is a schematic side view of the indoor unit of the air conditioner. Such as figure 1 As shown, the outdoor unit 22 has an outdoor heat exchanger 24, a compressor 25, and a blower fan 26 as main components.
[0022] This air conditioner is a so-called constant speed air conditioner, and the outdoor unit 22 does not have an outdoor temperature sensor that detects the outdoor air temperature and sends the temperature to the indoor unit side, a heat exchanger temperature sensor that detects the temperature of the outdoor heat exchanger, etc., and can directly detect the temperature of the outdoor unit. Environmental device.
[0023] That is, on a model capable of power supply to the compressor, power supply to the pump, and switching between air-conditioning and heating, th...
Embodiment 2
[0040] Next, for Example 2 refer to Figure 5 Be explained. In Embodiment 2, the current detection device 5 used to detect the operating current in Embodiment 1 is replaced by a voltage detection device 5b, and the current memory device that stores a preset current is replaced by a device that stores a preset voltage. Refer to Figure 5 The workflow is described.
[0041]First, in step 27, the voltage value Va detected by the voltage detection sensor 33 as a voltage detection device is read into the CPU 12 via the input circuit; Compared with the first set voltage va1, if Va
[0042] In step 30, the voltage Va is compared with the second set voltage va2 preset in the memory 13, and if va1≦Va
Embodiment 3
[0044] Next, for Example 3 refer to Figure 6 The flow chart is described. In Example 3, the continuous operation pump is controlled without operating the detection device for a predetermined time from the start of the operation of the oxygen-enriched air supply device.
[0045] First, in step 34, the time T from the start of the oxygen-enriched operation is read into the CPU 12 through the input circuit 11 by the timer of the running time detection device; Compared with the preset time t1, if T

Abstract
An air conditioner is provided with: an oxygen-enriched membrane that separates oxygen and nitrogen in the air and allows oxygen to pass through, a pump that generates a pressure difference on the side where the oxygen passes through to transport oxygen, a driving device that drives the pump, A current detection device that detects the operating current of the air conditioner, and a current memory device that memorizes a preset current; it is also provided with: relative to the current value detected by the above-mentioned current detection device, according to the current stored in the set current memory device A central processing unit that sends signals to the drive unit, and an air blower that exhausts nitrogen and the like from the side that does not pass through oxygen. Therefore, in this type of air conditioner, in the oxygen-enriched supply device using the oxygen-enriched membrane, the pump load is varied according to the temperature characteristics of the oxygen-enriched membrane to stabilize the temperature rise of the pump motor.
Description
technical field [0001] The invention relates to an air conditioner with oxygen enrichment function. Background technique [0002] This air conditioner with the oxygen-enriched air supply device proposed in the past is equipped with air-conditioning devices such as heating and cooling and air separation devices for separating oxygen and nitrogen in the air; this air separation device consists of separating oxygen and nitrogen. A functional membrane that allows oxygen to permeate, a pump for generating a pressure difference on the oxygen-enriched side of the functional membrane, and an air blower that discharges nitrogen and the like on the oxygen-impermeable side of the functional membrane (refer to Japanese Patent Publication No. 7-30927). [0003] However, the oxygen-enriched membrane, as the above-mentioned functional membrane for separating oxygen and nitrogen and permeating oxygen, has the following functions: Figure 7 Shown is a temperature characteristic in which the...
