Heat Pumps
A heat pump system consists of 3 components: the heat source, the heat pump itself and a heat distribution storage system. Heat pumps are able to produce more energy than they consume by using conventional refrigeration cycle to absorb heat from the environment (Air / Ground / Water) and raise it to a suitable level for heating. Heat pumps are among the most efficient heating and hot water systems available today. Approximately 75% of the energy needed for heating comes from the environment. This means that for every 1kWh of electricity used to power the heat pump compressor, between 3 and 4 kWh of heating energy are produced, giving the heat pump an efficiency of 300-400% or higher.
Air Source Heat Pumps
Air Source heat pumps utilise the outside air as their energy source. Air source heat pumps can even extract heating energy from the outside air at temperatures as low as -25˚C. The UK has a relatively moderate winter climate compared with central Europe with average winter temperatures of around 5°C and air source heat pumps can achieve seasonal co-efficient of performance comparable with ground source heat pumps without the additional cost of expensive ground loop collectors ground work. An air source heat pump system is normally designed to deliver 100% of the heating and hot water demand. Taking into account investment costs and efficiency the heat pump itself is typically sized to provide at least 95% of the heating requirement and the remaining energy demand is normally from a supplementary heat source, most commonly an electric immersion heater, however in retro-fit applications it is also possible to combine the heat pump with an existing boiler.
Ground Source Heat Pumps
The earth stores an enormous amount of solar energy from both solar radiation and rainfall. At just 1m below the surface, the earth provides a stable source of heat throughout the year. At depths of 15m or more, the earth provides a constant 10°C temperature. Ground source heat pumps extract heat from the earth all year-round via ground heat collectors which consist of flexible poly ethylene pipes buried in the earth, either horizontally or vertically. A mixture of water and anti-freeze is then circulated through the pipe loops, attracting the heat energy and transferring it to the heat pump.
Water Source Heat Pumps
Water-to-water heat pumps extract enormous amount of thermal energy with high levels of energy efficiency by circulation the ground water directly through the heat pump evaporator "open loop collector". Year round high underground water temperatures 7-12ºC allow water to water heat pumps achieve very high levels of efficiency with COP's of 5 or over. Water to water heat pumps requires environment agency consent to extract and discharge water from/to the water course.
Air Conditioning
Air conditioning is the process of treating air so as to control simultaneously its temperature, humidity, cleanliness and distribution / air movement to meet the requirement of the conditioned space.
Comfort air conditioning is the process of treating air to meet the comfort requirements of the occupants within the conditioned space. The degree of control will very from one system to another.
Air conditioning system (Air to air heat pump) is a heat-moving mechanism, heat is absorbed in an evaporator in one location and released through a condenser in another location. The system can reverse its operation from cooling to heating using a special reversing valve so that the evaporator becomes the condenser and the condenser becomes the evaporator.
Single Split
Single split air conditioning system (reversible air to air heat pump) consist of one indoor and one outdoor unit. The indoor unit can be floor mounted, wall mounted, ceiling suspended, above the ceiling ducted or ceiling cassette type. The system can cool or heat depending on the mode selected. The outdoor unit can be floor mounted or wall mounted externally and either rejects or absorbs heat, according to the room's demand.
Twin, Triple or Quad Split
Twin, Triple or double twin split system work on exactly the same principle as a single split system, but using two, three or four indoor units all connected to one outdoor unit. – ideal for a single large room as it provide better air distribution than a large single split. All of the indoor units are operated by the same remote controller and therefore would not normally be applied to multiple rooms.
Multi Split
A multi split system consists of one outdoor unit connected to several indoor units, each indoor unit can be installed in a different room and controlled by it's own remote controller. The user has the freedom to set each indoor unit's temperature or fan speed, simultaneous heating and cooling is not possible all units must be set to the same operational mode (heating or cooling).
Heat Pump VRF / VRV (variable refrigerant flow / variable refrigerant volume) these systems modulate refrigerant flow depending upon the requirements of the building. Using inverter technology VRF / VRV systems are varying the compressor speed to match the cooling or heating load thereby consuming only the power necessary to match the requirement of individual rooms. Heat recovery VRF / VRV systems work on the same principles as heat pump system except that they can provide cooling and heating simultaneously and reuse the energy available in one or more areas of the building and transfer it to other areas in the building (additional energy saving). i.e. The system is diverting exhaust heat from indoor units in cooling mode to areas requiring heating. Each indoor unit can be individually controlled providing complete flexibility. VRF / VRV systems comprises of a condensing unit sited externally and series of multiple indoor units providing cooling and/or heating.
