<cfAbstr cfLangCode='RU' cfTrans='o'>Рассматриваются динамические характеристики газоохладителя теплового
насоса, полученные путем решения уравнений его динамики. Рассмотрена система
управления газоохладителем теплового насоса для подогрева сетевой воды, поступающей
от ТЭЦ в централизованную систему теплоснабжения. Показана возможность
использования ПИД–регулятора с коэффициентами, изменяющимися в зависимости от
режима работы газоохладителя для контура компенсации возмущений по температуре
прямой сетевой воды, поступающей на узел смешения прямой и обратной сетевой воды.</cfAbstr>
<cfAbstr cfLangCode='RO' cfTrans='o'>Sunt examinate caracteristicile de dinamică ale răcitorului de gaze al pompei de căldură,
care sunt obţinute prin soluţionare a equaţiilor lui de dinamică în derivate particulare. Este
examinat sistemul de dirijare a răcitorului de gaze pentru încălzire a apei de reţea, care este livrată
de la CET în sistemul centralizat de termoficare. Este demonstrată posibilitate a utilizării
regulatorului PID cu coeficienţii variabili în dependenţă de regimul de funcţionare a răcitorului de
gaze. Răcitorul de gaze este o parte a sistemului de stabilizare a apei tur în sistemul de termoficare
după nodul de amestec al apei retur şi apei tur de la CET.</cfAbstr>
<cfAbstr cfLangCode='EN' cfTrans='o'>There are examined dynamic characteristics of heat pump gas cooler, which are
obtained by means of the solution of equations of dynamics in partial derivatives. It is examined
the control system of the heat pump, which is used for the heating of the heating–system water,
supplied from CHP to the district heating system. Possibility of PID-controller with gain
scheduling utilization with the coefficients changing depending on gas cooler mode of operation
for temperature disturbances compensation of direct heating–system water is shown.</cfAbstr>
