HEAT PUMP

Posted on: 02/09/21

 

 

 

 

   

 

It is the electrical device that removes heat from one space or environment and transfers it to another. That is, it alternates the cooling cycle of the system, as a result of which it gives hot or cold air depending on the needs of the space.

It is an energy efficient system that absorbs heat from the ambient air for heating and hot water. It transfers the heat of the ambient air to the house through a hydraulic water system, such as underfloor heating, fan coil, and radiators.

 

 

 

Categories of heat pumps

MONOBLOCK and split type heat pumps SPLIT.

SPLIT:

Some systems are located on the outside of the machine (compressor, fans, etc.) and some inside (heat exchanger, circulator, etc.).

The indoor unit is the hydraulic unit where the part that will be connected to the hydraulic heating pipes is.

MONOBLOCK:

All individual systems (compressor, heat exchanger, fans, etc.) are mounted on a machine, which is mounted outdoors.

Easy installation, direct connection to the water system, no restrictions on the distance of the outdoor unit.

COP and EER efficiency coefficient

The Coefficient of Performance (COP) of the pump is the measurement that proves to us whether our pump is efficient in heating in relation to the amount of energy it consumes

COP = Thermal power output / Electric power consumption

EER is the efficiency factor of a heat pump in cooling:

EER = Cooling power efficiency / Electric power consumption

Όσο υψηλότερος είναι ο βαθμός απόδοσης τόσο πιο αποδοτική είναι η αντλία μας.

 

Annual SCOP rate of return

SCOP = Annual thermal energy efficiency / Annual electricity consumption

The annual SCOP efficiency factor is essentially the average COP for all heat pump operating hours.

Defined as the ratio of the total annual heating need to the total annual energy consumed in heating

 

 

Energy category

The energy category is defined, depending on the SEER and SCOP values according to the following table:

     

     

Air / Water Heat Pumps advantages
  1. Save money during system operation up to 65%
  2. Energy upgrade of the building / house.
  3. Dependence on the supply of fuels, such as oil, liquefied petroleum gas.
  4. Possibility of operation in cooling as well.
  5. Installation, both in new and existing buildings, without the need for internal interventions.
  6. Possibility of combination with PV system, so that the current produced by the photovoltaics, to supply the heat pump

 

 

 

Heat pump sizing option
To calculate the power required to have a heat pump to cover The heating of a house requires a mechanical study with which the thermal and cooling loads are calculated.

1) SPLIT SYSTEM: Cooling connections between indoor and outdoor unit

2) COMPRESSOR WITH INVERTER CONTROL: Variable speed compressor, adapted to the current demand for hot or cold water production. When the desired temperature is reached in a room and therefore there is less demand for hot or cold water in the system, the compressor operates at a lower rate, thus consuming less energy, producing less noise and increasing the efficiency of the pump.

3) COOLING POSSIBILITY: Minimum supply temperature up to + 7 ° C

 

 

NIBE SMO 20 / SMO 40 

1. Detailed information

Information on operating status, operating time and indications of system temperature sensors.

2.Heating-cooling control with underfloor heating-cooling or fan-coils

3. Possibility of remote control, via nibe uplink.

You can easily manage the heating system or receive a warning about its operation if required.
