Device and teeth It relates to the use of energy performance test method.

In general, air conditioner and heat pump is a unit that combines one or two casings with the necessary mechanical equipment to achieve the purpose of air conditioning (cooling, heating, dehumidification, humidification and purification of air). The shape, function and dosage vary.

Commonly referred to as air conditioner (cooling only) or heat pump (for both air conditioning and heating), the performance of air conditioners is expressed as energy efficiency value that expresses cooling / heating capacity and this heating / heating capacity by consumption input and capacity by consumption input. Can be.

The performance of this air conditioner helps the user to select the air conditioner suitable for the purpose or capacity among various products.

Since air conditioners vary in their performance, a test apparatus is needed to measure whether the heating and cooling performance of a factory manufactured product is accurate.

This test device follows the test method of the domestic standard (KS) or the international standard (ISO). When testing the energy performance of the air conditioner, the room on the outdoor side and the indoor side is implemented separately, and the temperature (dry bulb temperature) and humidity ( Wet bulb temperature) is precisely implemented according to the standard (for example, the dry bulb temperature at the outdoor side and the indoor side during the standard climate (T1) test, the wet bulb temperature conditions are 35 ° C / 24 ° C and 27 ° C / 19 ° C, respectively). In the case of high temperature cooling (T3, Hot Climate) test, it is 46 ° C / 24 ° C and 29 ° C / 19 ° C, respectively.

Tests based on these standards measure air-conditioning performance in a steady state by keeping the indoor and outdoor humidity levels consistent with the test conditions. In other words, by measuring the normal temperature and humidity of the air discharged from the product under a constant temperature and humidity conditions and the amount of heat (= cooling and heating capacity) of the product and the power consumption (or power consumption) at that time. In recent years, the inverter compressor air conditioner has appeared with the development of technology, and it is necessary to measure the seasonal performance according to the change of the outdoor temperature and humidity and the indoor heating and cooling load as well as the performance in specific temperature and humidity conditions.

The second heater 34, the second cooling coil 36a, or the indoor unit is driven to perform the control operation of the sensible heat control unit so as to follow the temperature, thereby realizing the daily or annual indoor cooling load required by the database 84.

In addition, the controller 80 of the present embodiment is short of the real-time heating load (winter cold air) of the building to be simulated after adding up the sensible heat (power consumption) generated by the second fan 36 and the turbo fan 74. As much as the sensible heat (cool air) can be controlled by the sensible heat of the second cooling coil (or thermoelectric cooler: 36a), the second consisting of 0-100% Open loop output control of the second cooling coil (or thermoelectric cooler: 36a) The sensible heat control unit of the cooling coil (or thermoelectric cooler: 36a) and the sensible heat matching 0 to 100% in advance are measured at several points and then interpolated, and the second cooling coil (or thermoelectric cooler: Pre-sensible heat measurement amount so that the output of 36a) can be controlled from 0 to 100%-the latent heat load of the building by humidifying the output% matching input part and interpolation calculation part and the second humidification supply pipe 37 of the second room 30.

By controlling only the sensible heat control unit of the second cooling coil 36a without operating the latent heat control unit of the device and the humidifying heater, the total amount of sensible heat and latent heat can be controlled to be matched only with sensible heat.
