Property owners who decide to install a heat pump always want to learn more about this type of systems before making the final decision. Investors need clear information on the principles of operation of such devices and factors affecting operating costs. Additionally, it is also worth familiarizing yourself with the guidelines on where such installations can be installed.
How does the installation of a heat pump begin?
Before installation works begin, it is necessary to carefully calculate what is the best selection of heating power in relation to the building’s demand for thermal energy. Calculating the heat demand of a house is calculated using specialized programs that take into account all the most important information related to the building’s thermal insulation.
Once you have the necessary calculations, you can proceed to selecting the appropriate heat pump. The simplest solution is to use a computer simulation program that will allow you to obtain information on the type of heating and the most important parameters of the selected heat pump unit. Even though such calculations are quite time-consuming, they must be performed because this is the only way to guarantee the correct operation of the entire system.
Location of the heat pump during installation
When choosing the appropriate place to install the heat pump, you should take into account that the distance of the device from the house wall cannot be less than 30 cm. This way, free air flow will be ensured.
The heat pump can be mounted on a system structure or a concrete plinth. It is important that the height from the ground level to the device is not less than 40 cm. This will protect the unit against fan blockage during heavy snowfall.
Installation of the heat pump cannot be carried out above the pavement due to condensate flowing down. The simplest solution in such a case is to mount the heat pump directly on the ground, which will allow a large amount of condensate to be easily removed. This will avoid wet surfaces during spring and autumn and icing during winter.
When choosing a place to install the heat pump indoor unit, you should take into account easy access to it. This is very important because you will need to perform service work on such a device and also provide appropriate power supply with an electric cable.
Refrigeration installation when installing a heat pump
When installing the heat pump, connect the outdoor unit with the indoor unit using appropriate refrigerant connections. Before connecting the units with gas, an appropriate connection tightness test must be performed. The test involves filling the heat pump system with nitrogen and must last approximately 40 minutes. Such a test will allow you to check whether everything was done correctly.
Appropriate arrangement of heat pump temperature sensors
An important parameter influencing the proper operation of the heat pump is the appropriate arrangement of temperature sensors. They decide when the device will turn on and when it will switch to another mode.
Here you need to remember about external temperature sensors, which must be placed in a shaded place. The sun’s rays may cause incorrect readings, which will reduce the supply temperature of the entire installation, which will result in underheating of the house.
The second very important sensor is the comfort temperature sensor. This is an internal sensor whose task is to monitor the temperature in the room. It must be placed at least one and a half meters from the floor level. Its installation should be performed in a temperature-neutral room.
Other additional sensors can also be installed in the heat pump, which depend on the level of automation of a given device.
Installation of a heat pump with automation
Nowadays, automation is an extremely important element in heat pumps. Proper setting of the entire system will have a key impact on reducing operating costs. All options should be set so that the pump can operate with the lowest possible supply temperature. Only this will ensure economical work.
Most heat pumps have manual and automatic controls, thanks to which the user can determine a specific temperature himself or decide to have the temperature set according to sensors and specific external and internal parameters.
