Abstract

PURPOSE:To realize space cooling and heating without using a four-way valve by partitioning an evaporator unit, an evaporator damper chamber, a condensation unit and condenser damper, and providing dampers for switching suction and exhaustion of air in respective units and chambers. CONSTITUTION:During space cooling, a first damper 27 of a condenser closes a passage from a second indoor suction port 35 to a condenser communicating port 31, a first damper 26 of an evaporator opens a first indoor suction port 33, a second damper of the condenser closes a second indoor discharge port 36, and a second damper of the evaporator closes a first outdoor exhaust port 39. External air flows to a condenser unit 22 through a second outdoor suction port and indoor air flows from a first suction port 33 to the evaporator unit 21 to discharge cool air through a first indoor discharge port 34. On the other hand, during space heating, each damper is switched, and thus external air flows to the evaporation port 21 via the first outdoor suction port 38, and indoor air flows to the condenser unit 22 via a second indoor suction port 35, thus discharging hot air through the second indoor discharge port 36. Thus, the space cooling and heating can be carried out and the structure of the air conditioner can be manufactured at a low cost.

Description

BACKGROUND ART Conventionally, a so-called heat pump type air conditioner that performs cooling and heating in one air conditioner has a configuration as shown in FIG. That is, the main body 3 of the heat pump type air conditioner is installed on the indoor side of the louver 2 provided in the opening of the wall 1. This main body 3 is composed of an outdoor unit section 5 divided by a partition plate 4 and an indoor unit section 6,
The outdoor unit section 5 includes an outdoor blower 7, and during cooling,
It is equipped with an outdoor heat exchanger 8 that acts as a condenser and as an evaporator during heating, sucks in outside air as shown by arrow A, and air that has passed through outdoor heat exchanger 8 goes outside as shown by arrow B. It is designed to be exhausted. On the other hand, the indoor unit section 6 includes an indoor blower 9, an indoor heat exchanger 1° that acts as an evaporator during cooling and a condenser during heating, a compressor 11 (dotted line), and an electrical equipment section 12. Indoor air flows in as shown by the arrow C, passes through the indoor heat exchanger 10, and is blown out into the room from the indoor air outlet 13 as shown by the arrow.

The heat pump type refrigeration cycle of the main body 3 is constructed as shown in FIG. Cooling and heating were performed by a heat pump type refrigeration cycle flowing to the 1° side of the exchanger.

Problems to be Solved by the Invention In such a conventional configuration, it is necessary to reverse the flow of refrigerant gas using the four-way valve 14 during cooling and heating, and the four-way valve 14 is very expensive. Therefore, the piping configuration becomes complicated and the cost increases.

In addition, when switching between cooling and heating, a loud switching sound is generated when the four-way valve 14 is activated, which is audible to the occupants, can lead to misdiagnosis of a malfunction, and furthermore complicates controllability. It had some problems.

The present invention solves these problems, and provides an air conditioner that uses a normal refrigeration cycle to perform heating and cooling, thereby reducing costs, eliminating switching noise, and simplifying controllability. The purpose is to provide

Means for Solving the Problems In order to solve this problem, the present invention divides the evaporator unit and the condenser unit into upper and lower parts of the main body using horizontal partition plates, and also separates the evaporator unit and the condenser unit. The evaporator damper chamber and the condenser damper chamber are separated by a vertical partition plate, and the evaporator unit and condenser unit are provided with an indoor air outlet and an outdoor exhaust outlet on the front and rear surfaces, respectively, and the indoor air outlet is provided inside.

Warm air generated by the heat of condensation is blown into the room from the indoor air outlet of the condenser unit through the condenser communication port to perform heating.

In addition, the first damper of the evaporator damper chamber closes the indoor air outlet of the evaporator damper chamber, and the outside air that flows in from the outdoor intake port of the evaporator damper chamber passes through the evaporator communication port and exits from the outdoor exhaust port of the evaporator unit. By exhausting the air to the outside and switching each of these dampers, heating and cooling can be performed using only the refrigeration cycle.
