Heat Pump Thermostat

 Over the past decade, the European market for heat pumps has been growing at a steady pace, with an annual growth rate of 10% from 2011 to 2020, resulting in the expected installation of 1 million heat pumps per year in in the year of 2021, indicating a market growth of 39% from 20201. In the next decade, by 2030, we do not only see a growth, but an actual acceleration of the yearly installation of heat pumps that will go up to 4 million, representing an annual growth rate of 20%. In other words, 1 out of 3 heating systems installed is going to be a heat pump, from 1 out of 10 in 2020. Although this shows a steep growth versus past years, we consider this as a minimum to move to a decarbonised residential heating market in Europe.

The key driver for growth has undoubtedly been the introduction of strengthened legislation governing new builds in many European countries, ranging from general regulations in France such as RT2012, which sets the new minimum standard of thermal insulation of dwellings, to a ban on combustion boilers in the Netherlands.

Battery Fast Charging Performance Test | Battery Charging Test

 The purpose of the battery charging performance test is to check the charging ability of the lithium-ion battery in different states. Battery charging performance test includes battery slow charging performance test and battery fast charging performance test.

Among them, battery fast charging refers to the mode of charging at a higher current rate. Fast charging is usually the act of charging at high current rates in a low SOC state of the battery system.

Battery fast charging performance tests were conducted at designed current rates in low, normal and high temperature environments. The specific test procedure is as follows.

1) Discharge the battery to the specified discharge cut-off conditions in a specific discharge procedure at ambient temperature.

2) The battery is left to stand at the target temperature.

3) At the target temperature, charge the battery with the set charging method until the charging cut-off condition, and record the charging capacity, charging energy and charging time. In addition, the internal temperature difference of the battery system at the end of charging needs to be recorded.

4) Put the battery in a normal temperature environment until the temperature is balanced.

5) Discharge the battery to the specified discharge cut-off conditions in a specific discharge procedure at ambient temperature, and record the discharging capacity and discharging energy.

Record the test results in Table 1-1.

Table 1-1 Record Sheet of Battery Fast Charging Performance Test

NO.	Condition	Charging time	Charging capacity	Charging energy	Temperature difference	discharging capacity	Discharging energy
1	Low temperature
2	Normal temperature
3	High temperature
Kindly reminder: Temperature chamber and battery test equipment are necessary equipment for battery charging performance test.

What is the Elmendorf Tear Test

The Elmendorf Tear Test is a method of testing the tear strength of paper, cardboard, or other related materials. This test is performed by measuring the force required to tear a sample in a specific direction. The force is measured by a tensile test machine and the results are typically expressed in grams per inch (g/in) or milligrams per millimeter (mg/mm). The Elmendorf Tear Test is used to determine the strength of materials such as paper, tissue, and laminates, and is also used to measure the amount of energy required to tear a material. It is an important quality control measure in the paper and printing industries.

Related machine of  Elmendorf test: GESTER Elmendorf Tearing Tester Falling-Pendulum Type

Elmendorf Tearing Tester Falling-Pendulum Type is applied to the determination of tear resistance of textile, and also can be used for paper, plastic sheets, film, electrical tape, sheet metal etc. The elmendorf tear strength test machine is a simple, yet powerful, testing device that can accurately measure the tearing strength of materials. This testing device is composed of two parts: a pendulum and a base. The pendulum is suspended from the base, and a test specimen is placed under the pendulum.It is measured by measuring the pendulum at a certain starting height to fall, all the potential energy into kinetic energy and then through the reduction of its potential energy converted into the work used to tear the fabric specimen, and then according to the original length of the textile sample to calculate the average tearing force.

Elmendorf Tearing Tester test method

The Tearing strength test method is based on the principle of tensile testing. In this test, a specimen is held between two clamps, and a specified force is applied in a specific direction along the specimen's length. The force is gradually increased until the specimen tears. The force required to tear the specimen is then measured.
