Air conditioning system

TL;DR: In this article, the running cost of the titled system is reduced by providing condenser and an evaporator in an outside air intake passage and an exhaust air passage and, in addition, a compressor to forcibly circulate refrigerant across said passages.

Abstract: PURPOSE:To contrive to reduce the running cost of the titled system by a constitution wherein a condenser and an evaporator are respectively provided in an outside air intake passage and an exhaust air passage and, in addition, a compressor to forcibly circulate refrigerant across said passages is also provided. CONSTITUTION:An outside air intake passage 1 and an exhaust air passage 2, both of which communicate respectively with a plurality of rooms R..., are formed independently with each other. An air conditioner A is provided in the outside air intake passage 1. On the other hand, an exhaust air unit B is provided in the exhaust air passage 2. In addition, a heat pump type heat recovery device 3 is provided across the outside air intake passage 1 and the exhaust air passage 2. An evaporator 3C arranged in the outside air intake passage 1, an air condenser 3D arranged in the exhaust air passage 2 and the like are provided in the refrigerant circulating cource 3B of a compressor 3A. During cooling operation, the refrigerant under high pressure gaseous state gives off heat necessary for the exhaust air from air-conditioned rooms to the exhaust air at the exhaust air side heat exchanger 3D. As a result, the refrigerant condenses itself and at the same time the exhaust air is heated. Furthermore, at the outside air side air heat exchanger 3C, the refrigerant is given heat from the outside and at the same time the outside air is cooled down and dehumidified.
