Abstract
1. Компрессионный тепловой насос, в особенности для бытового применения, например, рекуперации тепла из отработанной воды, предназначенный для холодильных аппаратов или систем кондиционирования или подобных устройств, содержащий компрессор (1) для хладагента, конденсатор (2), испаритель (3) и расширительный клапан (4), расположенный между конденсатором (2) и испарителем (3), а также переключающий клапан (5) для переключения гидравлического сопротивления расширительного клапана (4) между двумя фиксированными значениями гидравлического сопротивления, отличающийся тем, что в области точки впрыска хладагента в испаритель (3) предусмотрен датчик температуры, причем переключающий клапан (5) выполнен с возможностью переключения на пониженное гидравлическое сопротивление расширительного клапана (4), когда датчик температуры обнаруживает опускание температуры ниже заданного значения, и на повышенное гидравлическое сопротивление расширительного клапана (4), когда датчик температуры обнаруживает подъем температуры выше заданного значения.2. Тепловой насос по п.1, отличающийся тем, что расширительный клапан (4) образован двумя дроссельными заслонками с фиксированным гидравлическим сопротивлением, которые приводятся в действие переключающим клапаном (5).3. Тепловой насос по п.2, отличающийся тем, что переключающий клапан (5) выполнен в виде клапана двойного действия и осуществляет переключение между двумя дроссельными заслонками с различным гидравлическим сопротивлением.4. Тепловой насос по п.2, отличающийся тем, что обе дроссельные заслонки включены параллельно друг другу, а переключающий клапан (5) выполнен в виде включающ�1. Compression heat pump, especially for domestic use, such as waste water heat recovery, intended for refrigeration or air conditioning systems or similar devices, containing a compressor (1) for refrigerant, condenser (2), evaporator (3) and expansion valve (4) located between the condenser (2) and the evaporator (3), as well as a switching valve (5) for switching the hydraulic resistance of the expansion valve (4) between two fixed values of the hydraulic resistance, characterized in that in the area of the refrigerant injection point in the evaporator (3) is provided with a temperature sensor, and the switching valve (5) is configured to switch to a low hydraulic resistance of the expansion valve (4) when the temperature sensor detects a temperature drop below a preset value, and to an increased hydraulic resistance of the expansion valve (4) when temperature sensor detects temperature rise above the set value 2. Heat pump according to claim 1, characterized in that the expansion valve (4) is formed by two butterfly valves with a fixed flow resistance, which are actuated by a changeover valve (5). The heat pump according to claim 2, characterized in that the switching valve (5) is designed as a double-acting valve and switches between two butterfly valves with different hydraulic resistance. Heat pump according to claim 2, characterized in that both throttle valves are connected in parallel to each other, and the switching valve (5) is made in the form of an incl.
