The utility model object is achieved in that
A kind of heat-pump apparatus, comprise compressor, front heat exchanger, throttling arrangement and rear heat exchanger, it is characterized in that: also comprise at least one Intermediate Heat Exchanger and the second cross valve, four interfaces of the second cross valve connect respectively front heat exchanger, throttling arrangement, rear heat exchanger and Intermediate Heat Exchanger, and another interface of Intermediate Heat Exchanger and another interface of throttling arrangement are connected, this kind of heat-pump apparatus, by setting up at least one Intermediate Heat Exchanger and the second cross valve, just capable of being combined go out evaporation and the condensation proportionate relationship of multiple systems, coordinate again the parameter of the fan delivery that the multiple heat exchangers in adjustment System configure (or the water pump water yield etc.) to change, thereby the environment or the workplace that refrigerating capacity (heating capacity) are had to different demands are greatly met, thereby meet the different refrigeration of product adaptation or heat demand, the various solutions that different environments is formulated, make the use function of product abundanter, adaptive capacity to environment for use is stronger.
The utility model can also adopt following technical measures to solve:
As scheme more specifically, it can also include the first cross valve, and four interfaces of the first cross valve connect respectively the two ends of compressor, front heat exchanger and rear heat exchanger; This embodiment, by the conducting conversion of the first cross valve, make forward and backward heat exchanger operating mode conversion (evaporimeter and condenser function exchange), Intermediate Heat Exchanger also converts with the conducting of the second cross valve, realize corresponding evaporimeter or condenser function, so that the application of heat-pump apparatus is more extensive.
As scheme more preferably, the quantity of described Intermediate Heat Exchanger can be two to three, and each Intermediate Heat Exchanger is connected in series mutually; So that user, according to actual conditions, opens or the Intermediate Heat Exchanger of conversion respective numbers.
As another embodiment, the quantity of described Intermediate Heat Exchanger can be two to three, the connection parallel with one another of each Intermediate Heat Exchanger; This mode, user also can, according to actual conditions, open or change the Intermediate Heat Exchanger of respective numbers, realizes equally the purpose of this utility model.
Described throttling arrangement can be heating power expansion valve, capillary or electric expansion valve etc., and heating power expansion valve can regulate according to the evaporating temperature of evaporimeter the open degree of self valve, thereby regulates the cold medium flux that enters evaporimeter; Capillary cost is low, and welding procedure is simple, equally also can realize the effect of throttling; And electric expansion valve, it regulates cold medium flux more precisely, accurately; Certainly, throttling arrangement can also be other throttling device, will not enumerate here.
The beneficial effects of the utility model are as follows.
(1) heat-pump apparatus of the present utility model, by setting up at least one Intermediate Heat Exchanger and the second cross valve, just capable of being combined go out evaporation and the condensation proportionate relationship of multiple systems, coordinate again the parameter of the fan delivery that the multiple heat exchangers in adjustment System configure (or the water pump water yield etc.) to change, thereby the environment or the workplace that refrigerating capacity (heating capacity) are had to different demands are greatly met, thereby meet the different refrigeration of product adaptation or heat demand, the various solutions that different environments is formulated, make the use function of product abundanter, adaptive capacity to environment for use is stronger.
(2) have again, if heat-pump apparatus retains traditional the first cross valve, by the conducting conversion of the first cross valve, make forward and backward heat exchanger operating mode conversion (evaporimeter and condenser function exchange), Intermediate Heat Exchanger also converts with the conducting of the second cross valve, realize corresponding evaporimeter or condenser function, so that the application of heat-pump apparatus is more extensive.
