Full title and description

ISO 13612-1:2014 — Heating and cooling systems in buildings — Method for calculation of the system performance and system design for heat pump systems — Part 1: Design and dimensioning. This part establishes inputs, calculation methods and required outputs for design and dimensioning of heat-pump-based heating and cooling systems in buildings.

Abstract

ISO 13612-1:2014 applies to heat pumps used for space heating and cooling, heat-pump water heaters and combined systems (space conditioning and domestic hot water). It specifies required inputs, calculation methods and outputs for heat generation and control for electrically driven vapour-compression cycle (VCC) heat pumps, combustion-engine-driven VCC heat pumps and thermally driven vapour-absorption cycle (VAC) heat pumps, and gives design and dimensioning criteria for system configurations (water–water, brine–water, refrigerant–water, air–air, air–water and combined systems).

Scope

Defines calculation and design/dimensioning methods for heating and cooling systems in buildings that use heat pumps, either standalone or combined with other heat generators. Covers the heat pump, its interface with heat distribution and emission systems (including buffering), system control and aspects related to the system energy source; it does not set out the detailed design of attached subsystems (for example, DHW installations) beyond their impact on heat-supply sizing. Applicable to VCC (electric and engine-driven) and VAC heat pumps and a range of source/distribution combinations.

Key topics and requirements

• Required inputs and outputs for system performance and heat-generation calculations (steady-state design/data for sizing).
• Calculation methods for design and dimensioning of heat-pump systems supplying space heating, cooling and domestic hot water interfaces.
• Design criteria and sizing rules for different heat-pump types: electrically driven VCC, combustion-engine-driven VCC, thermally driven VAC.
• Support for multiple system configurations: water–water, brine–water, refrigerant–water (direct expansion), air–air, air–water and combined systems.
• Consideration of controls, buffering/storage interfaces and interaction with building distribution/emission systems.

These topics and requirements are drawn from the ISO 13612-1:2014 specification.

Typical use and users

Used by HVAC and building services engineers for design and sizing of heat-pump systems, energy modelers and consultants when modelling system performance, manufacturers and testing houses for defining interfaces and performance data, and standards bodies or regulators referencing calculation methodology for compliance or policy. It is intended for practitioners involved in the design, specification and assessment of building heat-pump systems.

Related standards

ISO 13612 is a multipart series; the principal companion document is ISO 13612-2:2014 (Part 2 — Energy calculation), which provides the energy calculation method and time-step modelling to complement Part 1’s design/dimensioning rules. The work is maintained under ISO/TC 205 (Building environment design). National adoptions (for example BS ISO 13612-1:2014) are available from member bodies.

A: ISO 13612-1:2014 is an international standard that specifies methods, inputs and outputs for the calculation, design and dimensioning of building heating and cooling systems using heat pumps.

Q: What does it cover?

A: It covers design and dimensioning criteria, calculation methods and required data for heat pumps supplying space heating, cooling and interfacing with domestic hot water systems; it addresses various heat-pump types and system configurations and the interface with distribution and control systems (but excludes detailed design of attached subsystems).

Q: Who typically uses it?

A: HVAC and building services engineers, energy modelers, consultants, heat-pump manufacturers and testing bodies, and standards or regulatory organizations that reference calculation and sizing methodology.

Q: Is it current or superseded?

A: ISO 13612-1:2014 was published in May 2014 and is listed as the 2014 edition (Edition 1). Users should verify the standard’s current status with ISO or their national standards body before relying on it for compliance, and check for any subsequent confirmations or revisions.
