The balance type calorimeter (equilibrium chamber calorimeter) can achieve extremely accurate capacity measurements by minimizing heat leakage from the test chamber to near "zero." By keeping the test conditions at standard conditions (constant), this measurement method is ideal when highly accurate capacity measurements are required. This type features an additional temperature-controlled chamber (outer chamber) outside both the indoor and outdoor test chambers, creating a double structure that maintains thermal equilibrium between the indoor and outdoor test chambers and eliminates temperature differences during capacity measurements. The capacity measurement method for the specimen (room air conditioner) on the indoor side is conducted using a direct method, measuring the cooling and dehumidifying capacity for cooling, and the heating capacity for heating, balancing it with the thermal capacity of the measuring device to measure the thermal input. The same method is used for the outdoor side to measure the thermal input during cooling and heating, and it is stipulated that the calculated values based on the outdoor measurements must match the indoor measurements within 4% (JIS).

The compressor calorimeter CALOACE 21 (gas refrigerant flow measurement method) is a method that measures the flow of gas refrigerant circulating within the cycle to test the cooling capacity of various compressors, such as package air conditioners, room air conditioners, car air conditioners, and refrigerators. There are several measurement methods available, but until now, the evaporator calorimeter method (secondary refrigerant calorimeter method) and liquid refrigerant flow measurement method have been used. Satake has pioneered the development and adoption of the gas refrigerant flow measurement method in this field in Japan. CALOACE 21 is designed with consideration for environmental issues, eliminating the need for refrigerant gas (secondary refrigerant) required by the secondary refrigerant calorimeter method, and it can also reduce the refrigerant usage within the cycle by approximately 40%. It is the newest method of compressor calorimetry that offers energy savings and higher reliability in reproducibility. For more details, please contact us or refer to the catalog.

The Satake fan performance measurement device/soundproof wind tunnel device is a testing apparatus that measures the performance of fans such as centrifugal fans, cross-flow fans, and propeller fans, including static pressure (P), airflow (Q), and noise. The direction of airflow within the chamber can be easily switched to reverse with simple operations. The inlet air can be conditioned to specified settings, allowing tests to be conducted under the same conditions at all times. All measurements, including nozzle selection, are automatically collected and processed, enabling the creation of tables and graphs. For more details, please contact us or refer to the catalog.

The car air conditioning bench test device is a simulation testing apparatus for car air conditioning, designed to condition the air in the vehicle cabin based on an actual car configuration. The cooling and heating capacities are determined on the cabin side. The measurement method is based on the air enthalpy method. On the outside of the vehicle, an electric motor is used as the compressor drive source instead of an engine, controlling the ambient temperature and rotation speed of the compressor, and measuring torque. On the condenser side, a flow measurement device that can control airflow based on inlet wind speed standards is also employed. The flow measurement device consists of an air intake chamber, nozzle section, rectifier, auxiliary fan, differential pressure control, and measurement equipment. In this device, the evaporator-condenser (test sample) is directly mounted in the air intake chamber. For more details, please contact us or refer to the catalog.

The Satake Prefabricated Environmental Testing Room boasts unique know-how, stable ultra-precise accuracy, and energy efficiency, featuring constant temperature and humidity rooms, constant temperature rooms, low-temperature constant temperature rooms, and ultra-low temperature constant temperature rooms. This can be considered a special skill unique to Satake, which has a long-standing track record. It is equipped with a bright, easy-to-read LCD display temperature (humidity) controller and has a wide range of functions in addition to temperature and humidity control. Since humidity can be set directly as relative humidity, it can also be displayed and recorded as relative humidity. Depending on your needs, it is possible to automatically select equipment, program control, and accumulate and transfer data for appropriate cooling and humidification of controlled temperature and humidity using a computer or touch panel controller. For more details, please contact us or refer to the catalog.

• Environmental Test Equipment

The automotive environmental testing chamber conducts tests on real vehicles (including electric vehicles) under natural environmental conditions such as temperature, humidity, wind speed, and atmospheric pressure, covering everything from engine performance and car electronics to interior equipment. It is a device large enough to accommodate actual vehicles while reproducing those natural environments. Performance tests include the power performance of the vehicle with the engine and drive wheels in operation, as well as tests for engine RPM, torque, output, and fuel consumption. It also includes tests for the cooling performance of the engine and radiator, the lubricating properties of oil at low temperatures, and the performance of vehicle air conditioning systems. Using a solar radiation device, it tests temperature changes indoors due to sunlight. Additionally, it involves research on the structure and materials of the vehicle body and interior equipment, as well as the development and testing of various sensors related to car electronics. For more details, please contact us or refer to the catalog.

In order to meet the required noise levels, sound-absorbing wedges and materials are installed on the walls of the room to reduce sound reflection. Additionally, an air conditioning unit equipped with a soundproofing device creates an environment where the acoustic characteristics of the noise emitted from the test equipment, such as its volume, strength, and direction, can be measured under controlled temperature (humidity) conditions. Our motto is "To create products that satisfy our customers and can be used with peace of mind," and we thoroughly implement quality control with customer satisfaction as a key evaluation criterion.

As a comprehensive practical test for air conditioners, we can confidently respond with our comfort testing equipment (residential environment testing equipment) consisting of a model house and an outdoor environmental chamber. In the residential environment, we conduct tests including the calculation of PMV values (Predicted Mean Vote) and PPD values (Predicted Percentage of Dissatisfied), as well as airflow distribution curves through wind speed traverses. In the outdoor environment, we also meet a wide range of requests by simulating various meteorological conditions such as solar radiation, rainfall, wind, and snowfall.

• Environmental Test Equipment

The environmental testing of room air conditioners involves indoor units that correspond to indoor conditions and outdoor units that correspond to outdoor conditions, under which durability and weather resistance tests are conducted. In particular, for outdoor units, tests such as sprinkling, water impact, and thermal efficiency are performed. We create expected environmental conditions and faithfully and accurately simulate and reproduce them. For more details, please contact us or refer to the catalog.
