Features of a heating system using a heat pump

There are three main types of heat pump: air-to-air, air-to-water, and ground-to-water. You can read more about the types of heat pumps at the following link: https://reneco.com.ua/stati-teplovie-nasosu/kak-vybrat-teplovoy-nasos-dlya-otopleniya/ In our region (Odessa region), the most common hydraulic heating system uses water as a coolant. We propose to consider the basic requirements for such a heating system using a heat pump as the main heat generator. First of all, you need to understand that a heat pump is a low-temperature heat generator. The lower the temperature of the heating system coolant, the higher the efficiency. Heat pumps are capable of heating the coolant up to 80 °C and maintaining the set parameters for a long time, which allows them to be used in almost any heating system with forced water circulation.

Monovalent mode of operation of the heat pump:

a mode in which the heat pump provides all the necessary heat for heating or hot water supply, working independently, without additional heating equipment, such as, for example, a gas boiler or an electric boiler. This mode is designed for use throughout the entire heating period. Note that in order to achieve monovalent mode, the heating system with a heat pump must be correctly designed, configured and equipped with control and zone temperature control systems. Additional building insulation may also be required to retain heat.

Peculiarities:

Comfort and reliability.

The heat pump ensures a stable room temperature and operates reliably even at low temperatures. The monovalent mode is reliable because it does not require additional heating devices that can fail.

Environmental efficiency.

Using a heat pump in monovalent mode helps reduce CO2 emissions and promotes environmentally friendly heating as it uses the natural thermal energy of the environment.

Ease of use.

One heating and hot water system makes the control system simpler and more user-friendly

Bivalent mode of operation of a heat pump with parallel operation of heat generators:

A heat pump to provide heating and hot water supply in a house works in tandem with an additional heat generator (for example, a gas or electric boiler). When operating in this mode, the heat pump operates at moderate temperatures as the only heat generator, and at lower temperatures, the control automation of the heat pump gives a signal to connect another heat generator. The requirements of a heating system in dual-mode heat pump operation with parallel operation of heat generators usually include a number of technical and functional aspects to ensure the efficiency and reliability of the system. Here are some of the basic requirements: a properly selected heat pump, parallel compatibility with heat generators, insulation of the house, the possibility of manual control.

Peculiarities:

Efficiency.

Bivalent mode allows the heat pump to be used in those conditions where it operates most efficiently, and other heating sources are used only when necessary. This helps reduce energy consumption and heating consumption.

Automatic switching.

The system automatically switches from one heating source to another, depending on external conditions and system settings.

Reliability.

Bivalent mode can improve the reliability of the heating system, since it is possible to continue heating the house even if one of the heating sources fails.

Bivalent mode of operation of a heat pump with separate operation of heat generators:

The heat pump and heat generators operate separately, and are controlled by a control system that determines which heating source to use at a particular time based on specified parameters and conditions A dual-mode heat pump heating system with separate heat generators must be well designed and configured to ensure efficient and reliable heating in the home. Here are some requirements and recommendations:

- Correct selection of heat pump
- Compatible with other heat sources

The heat pump must be compatible with other heat sources such as a gas or oil boiler. This means integrated control systems and the ability to exchange heat between different sources.

- Correctly configured hydraulic system

The hydraulic system must be properly configured to distribute the home's heat and be able to switch between the heat pump and other heating sources.

Peculiarities:

Separate work.

In this mode, the heat pump and heat generators operate separately and not simultaneously. A heat pump is used when it is efficient and energy beneficial, for example in moderate temperatures where it can provide heat in an economical way. Other heat generators are activated when the temperature becomes too low for the heat pump to operate effectively.

Efficiency.

This mode allows you to optimize energy consumption and provide heating in an efficient way. The heat pump is used where it is most beneficial, and heat generators are switched on only when necessary.

Control.

The control system determines when and which heating source to turn on based on set parameters such as ambient temperature, heat pump power, etc.

Reliability.

This mode of operation can increase the reliability of the heating system, since both heating sources can function separately and interchangeably, which makes it possible to provide heating even if one of them fails.

Regardless of the operating mode of the heat pump, the heating system must be two-pipe, with forced circulation of the coolant. The heating system can be collector, associated or dead-end. The choice of system type depends on the customer’s wishes and technical solutions and does not affect the operation of the heating system with a heat pump.

For the greatest efficiency of a heating system using heat pumps, it must be low temperature,built on the basis of heated floors and fan coils, without the use of high-temperature elements.
