Abstract

CONDICIONADOR DE AR. A presente invenção refere-se a interromper uma operação no caso de uma alimentação de água ser interrompida durante uma operação e no caso de a água não ser fornecida no momento de iniciar um compressor, e pode evitar o congelamento. Em um condicionador de ar equipado com uma máquina de exteriores (1) com um trocador de calor do tipo placa (4), incluindo uma placa em que a água flui e uma placa onde o refrigerante flui, um compressor (2), e uma válvula de expansão exterior (5) e uma máquina de interiores (23) tendo um trocador de calor externo (25) a máquina de exteriores e a máquina de interiores são conectadas por uma tubulação de refrigerante (10,11), um sensor de temperatura (9) é fornecido na superfície lateral do trocador de calor do tipo placa, as temperaturas da placa em que a água flui e a placa onde o refrigerante flui são medidos pelo sensor de temperatura e uma operação do compressor é interrompida no caso de o valor do sensor de temperatura tornar-se igual ou inferior a um valor predeterminado.AIR CONDITIONER. The present invention relates to interrupting an operation in case a water supply is interrupted during an operation and in case water is not supplied at the time of starting a compressor, and it can prevent freezing. In an air conditioner equipped with an outdoor machine (1) with a plate-type heat exchanger (4), including a plate where water flows and a plate where refrigerant flows, a compressor (2), and a outdoor expansion valve (5) and an indoor machine (23) having an external heat exchanger (25) the outdoor machine and the indoor machine are connected by a refrigerant pipe (10, 11), a temperature sensor (9) is provided on the side surface of the plate type heat exchanger, the temperatures of the plate where the water flows and the plate where the refrigerant flows are measured by the temperature sensor, and a compressor operation is stopped in case the value of the temperature sensor becomes equal to or less than a predetermined value.
