CH₂ heating and cooling system is designed to have a temperature of 21-23°C. It works with a combination of ceiling panels and chilled beams which can be found above the windows. These beams create cool air at around 18°C. Heat is absorbed in the concrete ceilings and through the natural ventilation of the building will be removed. As approximately 70% of the ceiling is curved in shape, there is expected to be a 14% decrease in cooling energy usage by the natural ventilation process. Figure 1 show’s how the cooling of the offices is expected to work.

The predictions said that this summer was going to be another scorcher for most of the nation. That prediction has been pretty accurate so far.

As day time is starting to become more and more unbearable, as fans would only constantly stir the hot sticky air S around, so the researchers ended up in choosing this topic. The researchers chose this topic mainly because of the hot weather here in the Philippines. The constant high temperature was the reason this came up to the researchers’ minds. This homemade air conditioner, also known as the “Swamp Cooler”, can help take the edge off and make a little more bearable. Not only that, but it’s also very inexpensive, easy to make, rather effective, and can

Ahmet Y¨or¨uko˘glu and Erdinc Altug [7] The fuzzy controller based washing machine is designed using neural network which is based on fuzzy logic, neural network and its learning algorithm [7].

Cleaning your computer, components, and peripherals help keep everything in good working condition and helps prevent germs from spreading.

CEI’s Heat Ventilation and Air Conditioning system couples the passive strategy of thermal mass with a specialized HVAC system. This is done by circulating the air pumped in around the building and change the

Taking this above perspective as a situation and present the original research outcomes, which aims is to construct the pricing of mathematical model for temperature and find out, how the Colombian electricity markets are generating revenues due to the variations in the temperature fluctuation. The Colombian climate is very warm and tropical on the coast ad in the north, with a rainy season from Mat to November. Though the temperature fluctuates little throughout the year due to Colombia´s proximity to the equator, it does vary according to altitude. It is cooler in the upland areas and cold in the mountains and in the cooer times of the nights can be freezing. Bogota is always springs – like, with cool days and crisp nights, though when the sun is shining the days can get quite hot. The Amazon region generally stays warm and wet round.

Multilayer Perceptron (MLP) is an artificial neural network that learns nonlinear function mappings. An MLP can be viewed as a logistic regression classifier where the input is first transformed using a learned non-linear transformation. This transformation projects the input data into space where it becomes linearly separable. This intermediate layer is referred to as a hidden layer. A single hidden layer is sufficient to make MLPs a universal approximator.

Energy is wasted daily across the country due to insufficient conservation. During the winter, heat escapes through poorly insulated and unsealed doors, windows, and attics. During the summer, sunlight streams into the house, causing air conditioners to work harder and pump more air. Hallway lights and televisions are left on overnight, wasting crucial energy. Each of these inefficiencies, while by themselves are very small, add up and waste our money and resources.

19. Determine the COP of a heat pump that supplies energy to a house at a rate of 8000 kJ/h for each kW of electric power it draws. Also, determine the rate of energy absorption from the outdoor air. 20. Refrigerant-134a enters the condenser of a residential heat pump at 800 kPa and 35°C at a rate of 0.018 kg/s and leaves at 800 kPa as a saturated liquid. If the compressor consumes 1.2 kW of power, determine (a) the COP of the heat pump and (b) the rate of heat absorption from the outside

The thermal mass will absorb and store heat during daytime hours and return it to the space at a later time (Santamouris & Asimakoupolos, 1996). Therefore, passive cooling techniques that use heat sinks can act to either, modulate heat gain with thermal mass, or dissipate heat through natural cooling strategies. The design of a building is a very important factor which influences the cooling potential of a natural cooling technique. Natural cooling techniques includes: natural ventilation, night flushing, evaporative cooling, ground cooling and radiative cooling (Santamouris & Asimakoupolos, 1996).

The general performance of an air conditioning system is based on the coefficient of performance of the system. It is the ratio of heat extracted in

Liquid: state in which matter does not hold a definite shape but occupies a definite volume

This project is being undertaken to designe a control system for the fan speed according to the room temperature. It senses the
