INTRODUCTION The first large scale electrical air conditioning was inverted by Willis Havilland Carrier in July 17‚1902 at Buffalo‚ NewYork‚ just one year after he graduated from Cornell university with a masters in engineering. In 1928‚WillisHavilland Carrierimproved and developed the residential air conditioner for private home used which call “weather make”. Air conditioner‚ namely AC or air-con consists of 4 types of systems‚ which are window air conditioner‚split air conditioner ‚ packaged

heat from the inside of the earth. Most of the geothermal energy comes from magma‚ molten or partially molten rock. Which is why most geothermal resources come from regions where there are active volcanoes. Hot springs‚ geysers‚ pools of boiling mud‚ and fumaroles are the most easily exploited sources. The ancient Romans used hot springs to heat baths and homes‚ and similar uses are still found in Iceland‚ Turkey‚ and Japan. The true source of geothermal energy is believed to come from radioactive

EER = 12 / KW/ton • EER = COP x 3.412 If a chillers efficiency is rated at 1 KW/ton‚ • COP = 3.5 • EER = 12 Cooling Load in - kW/ton The term kW/ton is commonly used for larger commercial and industrial air-conditioning‚ heat pump and refrigeration systems. The term is defined as the ratio of energy consumption in kW to the rate of heat removal in tons at the rated condition. The lower the kW/ton the more efficient the system. KW/ton = Pc / Er (1) Where Pc = energy

Comparison of different types of blood pumps Nowadays‚ there are two main types of blood pumps: kinetic pumps and positive displacement pumps. Kinetic pumps: Centrifugal pump is one of the most familiar kinetic pumps. A centrifugal pump converts the input power to kinetic energy in the liquid by accelerating the liquid by a revolving device - an impeller. The most common type is the volute pump. Fluid enters the pump through the eye of the impeller which rotates at high speed. The fluid is accelerated

Several patients are hospitalized with Self Administered ECSIPs. The primary nurse for that patient is expected to understand how to operate and care for this particular pump. I was very unfamiliar with this device because I was not exposed to it during nursing school. The entry-level education of prepares graduates with the knowledge

The Split-type air conditioner Some rooms do not have external windows or walls. Difficulties arouse in creating sufficient air flow in the rooms‚ which can lead to discomfort for residents in terms of temperature and humidity. The split-type air conditioner can be used in these situations. Introduction: A split air conditioning simply means that the condensor (or sometimes referred to as the “outdoor unit”) is separated from the “indoor unit”‚ thus the term “split”. The split air conditioning
