Abstract

PROBLEM TO BE SOLVED: To improve an air conditioner with a rotary total heat exchanger in comfortableness and economical efficiency. SOLUTION: An air conditioner 1 with a rotary total heat exchanger, which conditioner 1 is connected to an outdoor unit 2 by way of refrigerant pipes 20 and 21, can control rotor-driving motors 8, 9 and 10 by using an outdoor air temperature sensor 12 and a user-side heat exchanger inlet temperature sensor 13 to detect the respective temperatures, and rotating rotary total heat exchanger rotors 5, 6 and 7 by way of control means 14.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling an air conditioner with a total heat exchanger that varies the total heat exchange efficiency by controlling the rotation speed of a rotary total heat exchange rotor.

[0002]

2. Description of the Related Art The prior art is disclosed in Japanese Patent Application No. 7-317717 (hereinafter referred to as "Application").
Whether the heating and cooling of the user-side heat exchanger by operating the compressor of the air conditioner is necessary to obtain a comfortable indoor air temperature, whether the heat recovery of the total heat exchange rotor is necessary, the outdoor air temperature Judging from the indoor air temperature, the compressor was stopped, and if air conditioning was possible by introducing outside air and operating the total heat exchange rotor, the total heat exchange rate of the total heat exchanger was constant. However, the temperature range of the outside air temperature in which this control can be used is narrow, and the use is limited.

[0003]

The prior art is based on the problem that when the air temperature required by the air supply side matches the outside air temperature and the air temperature obtained from the total heat exchange efficiency of the total heat exchanger, However, the usable temperature range was very narrow, and it was insufficient to improve comfort and economy.

[0004] An object of the present invention is to control the total heat exchange efficiency of the total heat exchanger with a certain range, thereby expanding the temperature range in which the compressor can be stopped.
Comfort and economy are improved.

[0005]

SUMMARY OF THE INVENTION An outside air temperature sensor is provided at an outside air inlet of a rotary type air conditioner with a total heat exchanger, and a use side heat exchanger inlet temperature sensor is provided at a use side heat exchanger inlet. In order to supply a comfortable indoor blowout temperature, the controller determines whether or not the indoor blowout temperature can be controlled within a variable range of the total heat exchange efficiency depending on the rotation speed of the total heat exchange rotor, and controls these.

Embodiments of the present invention will be described below with reference to FIG.

FIG. 1 shows a compressor 15, an outdoor unit blower 16,
Exhaust blower 3, air supply blower 4, rotary total heat exchange rotor 5, connected to outdoor unit 2 having non-use side heat exchanger 17, expansion valve 189, four-way valve 19 and refrigerant pipes 20, 21
6, 7; a rotor drive motor 8, 9, 10; a use side heat exchanger 11, an outside air temperature sensor 12, a use side heat exchanger inlet temperature sensor 13; 1, when controlling the supply air temperature as an air conditioner, the following control is performed without controlling the operation of the compressor 15 and the outdoor blower 16 of the outdoor unit 2 to provide comfort and economy. Improvement is possible.

When controlling the indoor supply air temperature to the required temperature, the outside air temperature detected by the outside air temperature sensor 12 and the use side heat exchanger inlet temperature sensor after the rotary type total heat exchange rotors 5, 6, and 7 are used. Based on the temperature detected at 13, the controller 14 calculates the current total heat exchange efficiency and the difference between the supply side required temperature and the use side heat exchanger inlet temperature, and uses the rotor drive motors 8, 9, and 10. By changing the total heat exchange efficiency of the rotary total heat exchange rotors 5, 6, 7 by changing the number of rotations, which is a range, the utilization side heat exchange after the rotary total heat exchange rotors 5, 6, 7 is performed. By setting the temperature of the unit inlet temperature sensor 13 to the required temperature on the supply side, comfort and economy are improved as compared with the above control.

[0009]

Since the present invention is configured as described above, it has the following effects.

[0010] When the indoor supply air temperature is controlled to the required temperature, the supply air temperature is controlled more economically by controlling the total heat exchange efficiency with the return air using the outside air introduction air temperature. Can also improve comfort.
