Operating Principle - TESY EVHP 9S 260 60 Instrucciones De Uso Y Mantenimento

1. INTRODUCTION
This installation and maintenance manual is to be
considered an integral part of the TESY heat pump
(hereafter referred to as equipment).
The manual must be kept for future reference until the
heat pump itself has been dismantled. This manual is
intended for both the specialized installer (installers –
maintenance technicians) as well as the end user. The
installation modes to be complied with in order to achieve
a correct and safe operation of the equipment as well as
methods of use and maintenance are described in this
manual.
In case of the sale of the equipment or the change of
owner, the manual must accompany the equipment to its
new destination.
Before installing and/or using the equipment, read this
instruction manual carefully and, in particular, chapter 4
relating to safety.
The manual must be kept together with the equipment
and, in any case, it must always be at the disposal of the
qualified personnel in
maintenance.
The following symbols are used inside the manual in
order to rapidly find the most important information:

1.4. Operating principle

The equipment belonging to the EVHP series is capable
of producing domestic hot water mainly by using heat
pump technology. A heat pump is
transferring thermal energy from a low temperature
source to another with a higher temperature and vice
versa (heat exchangers).
The equipment uses a water circuit consisting of a
compressor, an evaporator, a condenser and a throttle
valve; a liquid/gas coolant flows inside this circuit (see
paragraph 4.6).
The compressor creates a difference in pressure inside
the circuit that allows a thermodynamic cycle to be
obtained: this sucks the coolant fluid in through an
evaporator, where the fluid itself evaporates at a low
pressure by absorbing heat; it is compressed and driven
used towards the condenser where the fluid condenses at a
high pressure releasing the absorbed heat. After the
condenser, the fluid passes through the so-called "throttle
valve" and by losing pressure and the temperature starts
to vaporize, it re-enters the evaporator and the cycle
starts all over again.
