Which of these propositions are right (multiple answers)
a. A heat pump and a chiller works according to different principles
A heat pump delivers heat and cold
b.
C. A chiller delivers only cold
d. a heat pump pumps heat from low temperature to high temperature
e.
In a heat pump the compressor is always electrical
f.
A heat pump pumps water from an aquifer
g. A chillers pumps heat from low temperature to high temperature
h.
The COP of a heat pump is the evaporator heat divided by the energy input to the
compressor
The EER of a chiller is the evaporator heat divided by the energy input to the compressor
A chiller delivers heat at the condenser side
A heat pump delivers heat at the condenser side
A chiller delivers heat at the evaporator side
m. A chiller delivers cold at the evaporator side
n. In an absorption chiller heat is delivered in the absorber and the condenser
o. The Carnot COP depends a lot on the temperature difference between the evaporator and
the condenser
i.
j.
k.
I.
p. The Carnot EER is defined as the temperature in the condenser divided by the temperature
difference between the evaporator and the condenser
q. The Carnot efficiency accounts for the fact that the temperature in the evaporator is lower
than the temperature of the heat sink
