HFO 1234 YF AS AN ALTERNATIVE REFRIGERANT FOR AUTOMOTIVE AIR CONDITIONING
ABSTRACT
HFO 1234 YF is a fluorinated hydrocarbon with the formula CH2=CFCF3. It has been replaced for R-134 as a refrigerant in Automobile Air Conditioner .HFO 1234 YF highly energy efficient, exhibits low toxicity, and can be potentially used in direct expansion automotive A/C systems with minimal design modifications . The Pres ....etc

Introduction

Solar air conditioning refers to any air conditioning (cooling) system that uses solar power. This can be done through passive solar, solar thermal energy conversion and photovoltaic conversion (sun to electricity). New solar air conditioning research and development program, which should develop and demonstrate multiple new technology innovations and mass production economies of scale. Solar air conditioning will play an increasing role in zero energy and energy-plus buildings design.

Introduction

Due to varying conditions of heating, ventilating, cooling and dehumidification in atmosphere at various places, the air conditioning of automobiles is very essential. To maintain human comfort and improve internal atmosphere in an enclosed space, proper control of freshness temperature, humidity and cleanliness of air required.

In an automobile the air conditioning system involvs two main processes of heating and cooling. In the heating system, warm water from the engine cooling system is used. The heat required to warm t ....etc

How does it work?
Refrigeration and air conditioning is used to cool products or a building environment.
The refrigeration or air conditioning system (R) transfers heat from a cooler low-energy reservoir to a warmer high-energy reservoir
There are several heat transfer loops in a refrigeration system as shown in Figure 2. Thermal energy moves from left to right as it is extracted from the space and expelled into the outdoors through five loops of heat transfer:
Indoor air loop. In the left loop, indoor air is dr ....etc

Abstract
This paper proposes a method of automatic people
counting used in air-conditioning energy-saving. The method
has counted the number of people in the indoor environments
through three modules: image pre-processing module, image
marking module and people counting module, in order to
control air-conditioning controller to achieve the purpose of
saving energy. Through experiment comparing, image preprocessing
module chooses image graying, Gaussian average
filter, binarization and opening operation to optimize images.
The ....etc
