How effective is underfloor cooling?

The soil is not so good to provide cooling because it is slow to react, has low cooling densities and condensation may occur. The efficiency of passive or free cooling depends on the type of soil matrix with holes are more effective.

How energy efficient is a portable air conditioner?

The best portable air conditioners have an energy efficiency ratio (ERR) of more than 9.9... ENERGY STAR air conditioners have an ER of about 10.7 or less under 20,000 BTU, and 9.4 or more than 20,000 BTU. Therefore, look for ER ratings in this range to get the best portable air conditioners in terms of efficiency.The best portable air conditioners have an energy efficiency ratio (ERR) greater than 9.9.

How effective are cooling fans?

Small and medium sized fans will provide efficient cooling in an area of diameter from 4 to 6 feet, while larger fans are effective up to 10 feet. A larger blade will also provide cooling comparable to a lower speed than a smaller blade.Small and medium sized fans will provide effective cooling in an area of 4 to 6 feet in diameter, while larger fans are effective up to 10 feet. A larger blade will also provide similar cooling at a speed below a smaller blade.

What is chiller efficiency?

The calculation of the efficiency of a refrigerator is quite simple. It is measured in COP which means Performance Coefficient. Performance Coefficient is only a proportion of the cooling effect produced by the refrigerator to the amount of electricity that has entered the machine to produce this.Calculating the efficiency of a cooler is quite simple. It is measured in the COP, which means Performance Coefficient. Performance Coefficient is only a link of the cooling effect produced by the cooler with the amount of electricity that entered the machine to produce this.

What is the efficiency of heat pumps?

An air source heat pump (ASHP) usually produces a thermal energy of about 3kW for each 1kW of electricity consumed, providing an effective efficiency of 300. It is thermodynamically impossible to have an efficiency of more than 100, as this implies that more energy is produced than put into it.A heat pump with air source (PSA) usually produces a thermal energy of about 3kW per 1kW of electricity consumed, which will give an effective efficiency of 300. It is thermodynamically impossible to have an efficiency of more than 100, since this implies that more energy is produced than used.
