Title (EN) COOLER AND AIR CONDITIONER
(FR) REFROIDISSEUR ET CLIMATISEUR
(JA) 冷房機、及び、空気調和機
Abstract:
(EN) Provided are a cooler and an air conditioner with which it is possible to appropriately prevent the device from reaching an overload operating state, even when an outside air temperature sensor and/or an outdoor heat exchanger temperature sensor is not provided. An air conditioner 1 is equipped with: a refrigeration cycle (cooling mechanism) having a compressor 52; a power calculation unit 22 that calculates power values for the compressor 52; and a rotational frequency control unit 21 that controls the rotational frequency of the compressor 52. The rotational frequency control unit 21 determines whether the refrigeration cycle is in an overload state on the basis of the power values calculated by the power calculation unit 22 and the rotational frequency of the compressor 52, and controls the rotational frequency of the compressor 52 on the basis of the determination result.
(FR) L'invention concerne un refroidisseur et un climatiseur permettant d'empêcher de façon convenable que le dispositif atteigne un état de fonctionnement en surcharge, même sans utilisation d'un capteur de température d'air extérieur et/ou d'un capteur de température d'échangeur de chaleur extérieur. Le climatiseur (1) comprend : un cycle frigorifique (mécanisme de refroidissement) comportant un compresseur (52) ; une unité de calcul de puissance (22) destinée à calculer des valeurs de puissance pour le compresseur (52) ; et une unité de régulation de la fréquence de rotation (21) destinée à réguler la fréquence de rotation du compresseur (52). L'unité de régulation de la fréquence de rotation (21) détermine si le cycle frigorifique est en état de surcharge sur la base des valeurs de puissance calculées par l'unité de calcul de puissance (22) et de la fréquence de rotation du compresseur (52), et régule la fréquence de rotation du compresseur (52) sur la base du résultat de la détermination.
(JA) 外気温センサ及び室外熱交換器温度センサの少なくとも何れかを備えていない場合にも、装置が過負荷運転状態となることを適切に抑えることのできる冷房機及び空気調和機を提供する。空気調和機1は、圧縮機52を有する冷凍サイクル(冷却機構)と、圧縮機52の電力値を算出する電力算出部22と、圧縮機52の回転数を制御する回転数制御部21とを備えている。回転数制御部21は、電力算出部22によって算出された電力値と、圧縮機52の回転数とに基づいて、冷凍サイクルが過負荷状態であるか否かを判定し、その判定結果に基づいて圧縮機52の回転数を制御する。
