Introduction
ClimaCheck
1
is a measuring and analysing system developed to give detailed evaluation of
refrigeration, air-conditioning and heat-pump systems in development laboratories, production
tests and in the field.
The method is based on measurements in the refrigeration circuit and does not require any fixed
installation of metering equipment in the system. The advantages of easy connection, immediate
and detailed information makes the ClimaCheck method superior for evaluating all refrigeration,
air-conditioning and heat pump systems.
An increased focus on energy efficiency can be seen in the
the Energy Performance of Building
and several other requirements on energy
performance on other markets. This directive requires annual inspections with
verifications of energy efficiency of all AC systems with more that 12 kW rated capacity.
Measuring with ClimaCheck gives and excellent foundation for performance inspections.
The ClimaCheck Performance Analysing method allows
complete analysis
of energy performance
as well as presenting all information to validate the individual components and their optimization
without the requirement of any fixed equipment making it possible to immediately identify and
locate any deficiencies in the system. The method was patented in 1986 and has since been used
in Sweden and internationally in the Product ETM 1500, ETM 2000, ClimaCheck PA 8:7 and now
ClimaCheck PA Pro.
The server based monitoring software is constantly logging the performance of the system and
uses the globally accepted equations for refrigerant properties in RefProp established by NIST
(National Institute of Standards and Technologies in USA). Anyone with the user name and
password can log in to the system from an Internet connected PC as well as have the server send
alarms when important parameters fall outside of their specified ranges.
The ClimaCheck method is suitable for almost all compressor-based refrigeration processes. All
suction or discharge gas cooled hermetic and semi hermetic compressors can be fully evaluated
without any compressor or system specific information. For open compressors the electrical motor
efficiency is given as input and for compressors with external cooling of air, water, oil or liquid
injection information on the cooling need to be entered to give a full capacity and COP accuracy.
For many types of systems data on compressor cooling are well known and necessary parameters
are known. ClimaCheck Specialists should be consulted to give advice on non-standard systems.
