Puerto Maldonado, 04 de agosto de 2020
Con respecto al documento es un honor dirigirme a Ud. para saludarlo e informar lo siguiente:
INTRODUCCION
En el presente informe es por mantenimiento preventivo y estado de 4 equipos de aire acondicionado en las oficinas N.'2 1 {A/AC 12000 BTU), N'22 (A/AC 12000 BTU), sala conferencia (A/AC 24000 BTU) y laboratorio (A/AC 18000 BTU), que por el tiempo de vida y por sonidos inadecuados y vibraciones, chillidos de los ventiladores y por usos de refrigerantes no eco16gicos (R22) en la unidad de condensacion y en las unidades evaporadoras fallas de control remoto, fUtros de malla para polvo deteriorado, carcaza exterior resecos y amarillentos. Los equipos actualmente estan operativos dado que tienen un mantenimiento preventive y correctivo, pero dado el deterioro de algunos componentes extemos e internos, tomamos la decision de informarle que si tuvieran un funcionamiento continua los equipos presentarfan diferentes fallas que saldrfan de la mano de los tecnicos poder solucionarlos por los desperfectos ya mencionados.
OBJETIVO
Se sugiere el cambio de dichos equipos por equipos ecol6gicos mas amigables con el medio ambiente
(R410) y que a su vez tengan la opci6n de REINICIO AUTOMATICO, ya que al estar en una zona de apagones intempestivos ya sea por factor�s_ huma nos o naturales, puedan encender con un reinicio automatico sin necesidad de un usuario
