Purpose The key purpose of this paper is to quantify the size of the energy-efficiency gap (EEG) for air conditioners at the household level in Delhi. Most of the studies in the EEG tradition broadly define EEG as the difference between the actual and optimal level of energy efficiency. The...

Free cooling is an effective way to make good use of night cold energy and helps to reduce air-conditioning energy consumption in the daytime. This research proposed integrating a new-type of shell-and-tube based phase change material (PCM) thermal storage system with conventional...

A multi-unit heat pump is presented for simultaneous humidity and temperature control to improve the energy efficiency and the thermal comfort. Two parallel connected condensers are employed in the system, locating at the back of the indoor evaporator and the outdoor unit, respectively. The heat...

In order to improve the modeling of air conditioners in building simulation tools, the characteristic curves for total cooling capacity, sensible cooling capacity and energy efficiency ratio of two room units were determined. They were obtained by means of standard capacity tests on climatic...

An adsorption cooling machine with LiCl/Silica gel–methanol was designed and tested, which can work for air conditioning and cold storage. The machine can be driven by low temperature heat source, such as solar energy and industrial waste heat. The composite adsorbent of LiCl/Silica gel has...

A chemisorption air conditioner with NaBr/expanded graphite composite sorbent and NH3 as refrigerant was designed and constructed to be powered by low temperature heat. The effect of independent variables (chilled water inlet temperature, heat source temperature and cycle time) on the...

To reduce the uplift pressure of groundwater, many wells, deep into the Chingmei gravel stratum underneath Taipei city, were installed during construction of Taipei MRT underground stations. These wells can also be used to establish a circulating groundwater system for air-conditioning. To study...

This paper presents the studies conducted on the effect of climate change on the air conditioner in terms of performance and reliability in the tropics. Basically, three aspects of impact were focused, which were cooling and heating load, electricity consumption and outdoor design conditions for...

Biogas engine-driven heat pump air conditioner is a new-style system which includes biogas engine-driven heat pump, primary heat exchanger, second heat exchanger, sprayed room and fans, pumps, etc. In summertime, the air can be reheated by the waste heat water from the biogas engine in the...
