How to work for air source heat pump

Air source heat pumps

Heat your home with energy absorbed from the air around you

Air source heat pumps absorb heat from the outside air. This heat can then be used to warm water for radiators or underfloor heating systems, or to warm the air in your home.

How do air source heat pumps work?

An air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can extract heat from the air even when the outside temperature is as low as minus 15° C.

There are two main types:

·               An air-to-water system uses the heat to warm water. Heat pumps heat water to a lower temperature than a standard boiler system would, so they are more suitable for underfloor heating systems than radiator systems.

·               An air-to-air system produces warm air which is circulated by fans to heat your home.

The efficiency of air source heat pump systems is measured by a coefficient of performance (CoP) - the amount of heat they produce compared to the amount of electricity needed to run them. A typical CoP for an air source heat pump is around 2.5.

The benefits of air source heat pumps

·               Reduce your fuel bills: air source heat pumps run on electricity, so there's no need to pay for gas, oil or solid fuels to heat your home.

·               Cut down on wasted electricity: heating your home with an air source heat pump is much more efficient than using electric radiators.

·               Save space: an air source heat pump system is compact, and requires no storage space for fuel.

Is an air source heat pump suitable for my home?

To tell if an Air source heat pump is right for you, there are a few key questions to consider:

·               Do you have somewhere to put it? You'll need a place outside your house where a unit can be fitted to a wall or placed on the ground. It will need plenty of space around it to get a good flow of air.

·               Is your home well insulated? Since air source heat pumps produce less heat than traditional boilers, it's essential that your home is insulated and draught proofed well for the heating system to be effective.

·               What fuel will you be replacing? The system will pay for itself much more quickly if it's replacing an electricity, Liquid Petroleum Gas (LPG) or coal heating system than a gas one.

·               What type of heating system do you want? Air source heat pumps are much better at powering underfloor heating systems or warm air heating than radiator-based systems.

·               Is the system intended for a new development? Combining the installation with other building work can reduce the cost of installing the system.

Costs and savings

Costs for installing a typical system suitable for a detached home range from about £5,000 to £10,000 including installation. Running costs for space heating are likely to be around £440 per year. This will vary depending on a number of factors - including the size of your home and how well insulated it is.

Savings can be considerable - up to 6 tonnes of CO2 and £870 per year for a system that replaces an electric heating system.

Air source heat pumps

by: zhonglv   Keywords: Air, source, heat, pumps

   An air source heat pump can provide efficient heating and cooling for your home, especially if you live in a warm climate. When properly installed, an air source heat pump can deliver one-and-a-half to three times more heat energy to a home than the electrical energy it consumes. This is possible because a heat pump moves heat rather than converting it from a fuel, like in combustion heating systems.

   Although air source heat pumps can be used in nearly all parts of the United States, they do not generally perform well over extended periods of sub-freezing temperatures. In regions with sub-freezing winter temperatures, it may not be cost effective to meet all your heating needs with a standard air source heat pump.

   However, new systems with gas heating as a backup are able to overcome this problem. There is also a "Cold Climate Heat Pump" which shows promise, but is currently facing manufacturing problems. In addition, a version called the "Reverse Cycle Chiller" claims to be able to operate efficiently at below-freezing temperatures.
 
   All we know that, the heat pumps need energy. When we enjoy the convenience brought by heat pumps, we also should remember saving energy. So we have a good solution for energy saving:
  • A good solution for energy saving
  • Chengda air to water heat pump is anew generation heat pump product developed with the advanced heating technologies. The heat pump utilizes the energy from surrounding air and converts the energy to the hot water for house heating and domestic hot water supplying. The whole range of this heat pump is completed and strictly tested with our European partners, to make sure the best efficiency and quality to European market. especially for cold areas. With wide running temperature range from -15? to 40?,keep supplying the warm water from 35? to 60?(max), making you warm and comfortable life.

European Air To Water Heat Pump

by: zhonglv   Keywords: cassette, air, conditioner

Summary
The purpose of the project was to build a low energy and low cost prefabricated house without compromising the comfort. Due to the overall reduced energy consumption in low energy houses the proportion of the heat required for DHW increases from 30% to 40%. This sets new requirements for a heating system. In this residence there are two air to water  heat pumps: one for heating (from October to April) and the other for DHW (DHW; all year round).


The former uses outdoor air and the latter indoor exhaust air as its heat source. The SPF of the 4.6 kW heat pump for space heating is 3.0. If auxiliaries such as fans for heat recovery and standby losses of the water heater are considered as well the SPF drops to 2.0.

Moisture Control

by: zhonglv   Keywords: Ceiling, air, conditioner

Properly controlling moisture in your home will improve the effectiveness of your air sealing and insulation efforts, and vice versa. Thus, moisture control contributes to a home's overall energy efficiency.

The best strategy for controlling moisture in your home depends on your climate and how your home is constructed. Before deciding on a moisture control strategy for your home, you may first want to understand how moisture moves through a home.

Moisture control strategies typically include the following areas of a home:

* Attics
* Foundation
o Basement
o Crawl space
o Slab-on-grade floors
* Walls.

In most U.S. climates, you can use vapor diffusion retarders in these areas of your home to control moisture.

Proper ventilation should also be part of a moisture control strategy.

How to choose an air conditioner ?

by: zhonglv   Keywords: Ceiling, air, conditioner

Most of people can get extremely hot and very few people can get by without some form of cooling in summer.

To install air-conditioning is a major purchase, hence it is worth making sure that your money is spent as wisely as possible. This advice applies for residential (home) room air conditioning units(Either reverse cycle or cooling only). Reverse cycle air conditioners are also sometimes called Horizontal Air Conditioner or heat pump. For offices and other commercial air conditioning, visit Ceiling air conditioner.

When choosing an air conditioning system, the following are the main criteria to consider:

  • Is heating required?
  • Comfort level
  • Purchase cost
  • Running costs
  • Noise levels
  • Reliability
  • Air conditioner brand
  • Confidence in the contractor
  • Outdoor unit location
