In above-mentioned frigorific unit Y, in order to realize refrigeration, to obtain the situation of cold water as described below.
Such as, when the kind of refrigeration cycle R1 ~ R4 compressor 17 separately driving the first system to unite to Quaternary system at the same time compresses cold-producing medium, the refrigerant gas after HTHP is discharged.Refrigerant gas is directed to a pair air heat exchanger 3 from cross valve 18, and carries out heat exchange with the air sent here by driving pressure fan S.Refrigerant gas condensation liquefaction, adiabatic expansion after being directed to expansion valve 19.
Then, liquid refrigerant interflow and temporal persistence after each acceptance division 10a ~ 10d, be directed to the first refrigerant flow path 40 in the first water heat exchanger 11 and second refrigerant stream 41, and carry out heat exchange with the water guiding to current road 33.The cold-producing medium of refrigerant flow path 40,41 evaporates and from the water on current road 33, captures evaporation latent heat, thus cools the water on current road 33, makes it become cold water.
In the first water heat exchanger 11, owing to comprising the first refrigerant flow path 40 and second refrigerant stream 41 that are communicated with respectively with the first system and kind of refrigeration cycle R1, the R2 of second system, therefore can cool water expeditiously.When the water sent here from water-circulating pump 13 is such as 12 DEG C, it is guided the refrigerant cools come 2.5 DEG C by by the kind of refrigeration cycle R1 of two systems, the refrigerant flow path 40,41 of R2 in the first water heat exchanger 11, and makes temperature be reduced to 9.5 DEG C.
Then, cold water after temperature reduces is directed to the second water heat exchanger 12 via the first water pipe arrangement P1, at this, the first refrigerant flow path 40 be communicated with the 3rd kind of refrigeration cycle R3, the 4th kind of refrigeration cycle R4 of dual system and second refrigerant stream 41 carry out heat exchange.
Therefore, the water be imported at 9.5 DEG C is again cooled 2.5 DEG C in the second water heat exchanger 12, is exported after becoming temperature to be reduced to the cold water of 7 DEG C.Above-mentioned cold water is directed to via delivery line i.e. the second water pipe arrangement P2 the place will carrying out air conditioning, cools being guided the air come by indoor fan, to realize refrigeration.
In addition, in each water heat exchanger 11,12, the cold-producing medium of evaporation is after being directed to gas-liquid separator 20 and carrying out gas-liquid separation via cross valve 18, again compresses, and repeatedly carry out above-mentioned kind of refrigeration cycle after being inhaled into compressor 17.
Like this, by the current road 33,33 of the first water heat exchanger 11 and the second water heat exchanger 12 is connected in series, two stages just can be divided to reduce the temperature of cold water, therefore, more effective refrigeration performance can be obtained.
First water heat exchanger 11 by being communicated with the first kind of refrigeration cycle R1 and the second kind of refrigeration cycle R2 of dual system, and can load a compressor 17 respectively in each kind of refrigeration cycle R1, R2.

Therefore, all kind of refrigeration cycle R1 ~ R4 is all independently, does not need to make to assign in compressor 17 at the lubricating oil of refrigerant loop Inner eycle, thus can prevent from causing performance to reduce because of point oil.Even if the kind of refrigeration cycle of a system shuts down, the kind of refrigeration cycle also by other three systems remains in operation, and the impact that running stops can be suppressed to minimum degree, thus can guarantee reliability.
In addition, because all compressors 17 and water-circulating pump are all power variable types, therefore, high efficiency running can be realized according to refrigeration load.
For realizing heating effect and to obtain the situation of warm water as described below.
After driving the compressor 17 of each kind of refrigeration cycle to compress cold-producing medium at the same time, discharge the refrigerant gas after HTHP.Refrigerant gas is directed to the first refrigerant flow path 40 the first water heat exchanger 11 from cross valve 18, and carries out heat exchange with the water guiding to current road 33 from water-circulating pump 13.In the first water heat exchanger 11, cold-producing medium is condensed liquefaction, utilizes the water of condensation heat to current road 33 to heat.
At this, because the first refrigerant flow path 40 of being communicated with the kind of refrigeration cycle of dual system and second refrigerant stream 41 are arranged in the first water heat exchanger 11 and the second water heat exchanger 12, therefore, can heat water expeditiously.Because the first water heat exchanger 11 and the second water heat exchanger 12 are connected in series, therefore, the temperature of warm water can be made to divide two stages to rise, can heating performance be improved.
The liquid refrigerant of deriving from the first water heat exchanger 11 is directed to the first acceptance division 10a and expansion valve 19, after carrying out adiabatic expansion, is directed to air heat exchanger 3,3 and evaporates.Cold-producing medium after evaporation is inhaled into compressor 17 via cross valve 18 and gas-liquid separator 20, and then is compressed, and repeatedly carries out above-mentioned kind of refrigeration cycle.In other kind of refrigeration cycle, circulate by identical path.
In addition, heat in running what obtain warm water, in a pair air heat exchanger 3,3 forming heat exchanger module M, cold-producing medium evaporates, thus makes the condensate moisture in air to adhere to drain water.If extraneous gas temperature is low-down low temperature, then accompanying drain water is frozen into frost and easily adheres to.Sensor senses above-mentioned frosting, signal is sent to the control electronic devices and components in control cabinet 8.
Control electronic devices and components send and will comprise kind of refrigeration cycle that sensor senses the air heat exchanger 3,3 of frosting from the instruction heating running and switch to cooling operation.Comprise sensor do not sense the air heat exchanger 3,3 of frosting kind of refrigeration cycle continue former state carry out heating running.
In the kind of refrigeration cycle switching to cooling operation, switch cross valve 18, make cold-producing medium guide to air heat exchanger 3,3 from compressor 17 via cross valve 18, carry out condensation and make it become liquid refrigerant.Discharge condensation heat along with the condensation change of cold-producing medium, frost attached to it is melted.
Owing to comprising shield 15,15 in the both sides of each heat exchanger module M, therefore, air can not leak between air heat exchanger 3,3 respect to one another, and air can be stoped to enter from adjacent heat exchanger module M.Therefore, the air heat exchanger 3,3 in defrosting running and the air heat exchanger 3,3 continuing to heat running can not produce heat affecting to each other.
In addition, such as cold-producing medium evaporates in the first refrigerant flow path 40 of the first water heat exchanger 11, to cool the warm water guiding to current road 33.But the second refrigerant stream 41 in the first water heat exchanger 11 is communicated with the second kind of refrigeration cycle R2 continuing to heat running, thus makes condensation of refrigerant, and condensation heat is released in the warm water of current road W.
Therefore, be maintained in minimum scope from the temperature reduction of the warm water the state that the first water heat exchanger 11 is derived.Consequently, if only make one group of kind of refrigeration cycle switch to defrosting running, the temperature of the warm water supplied from the first water heat exchanger 11 reduces seldom.
In addition, because all compressors 17 and water-circulating pump 13 are all power variable types, therefore, high efficiency running can be realized according to heating load.
