The theory of regenerative heat pump


・ Al Wu 0I) l ・ l group 2O94j Oh and the melting point 25n8409.5MgCh ・ 6H! On7 Liu peritectic point l725. 9 Fifth, the theory of regenerative heat pump cycle calculation example of a design for the outdoor design temperature for heating the object one by one 2 ℃,[link widoczny dla zalogowanych], the heating load of the column should be sampan = 135kW. When you hear the outdoor heating, the average temperature in t = 4 ℃. Manganese interior design degree t. A 2O ℃. Cut out corresponding to the heating load is tq when a q-(tI-t) / (【l-) = 135 × (20 a {) / (20-1-2) a 98'2kW \unit, may wish to use Shanghai Tang's Carrier soc ~-o4o ear unit. Refrigerant is R22. Corresponds to the degree of heat pump water manganese 45 ℃, the outdoor temperature and Ji are listed as follows hot ugly Table 2. Table 230 - 040 New Zealand and the performance table machines beyond the Great Wall temperature 1cl57 {0-5 - 10 a l5 mouth of the heat kwl43ll3l 854 & 59 & 876.8 dizzy. O power consumption kW dig 535l {3 | _23 & O30l62 & 225l8 Figure 4 grapes out of the heat so the performance curve. The assumption that indoor heating load and indoor and outdoor temperature difference is proportional to the premise. Circle is also given a load curve. When W = q ==--~==-- 2 ℃ t_ 2 ℃ when one by one. According to the conventional design, the auxiliary heating power required for the t54 refrigeration Re by the e,-rionIN99o5. z years 9295J9lI5J9l1)) in which the right side of the second type in one by one as t 2 ℃ heat production when the heat pump. Connected to the table we can see is 86. {{KW. Thus W = 135 - 86.44 = 48.56kW such as thermal heat pump cycle by Lei, in order that the heat pump heat production Pao to 135kW, Tony! F its to make the compressor into the steam temperature should be ambient temperature of 12. When the temperature of 8 ℃, do not have auxiliary heater was added. Corresponds to the map {, if selected for the evaporation temperature 7.8 ℃, the t-5 ℃. For the outdoor evaporator. One by one in t 2 ℃ ambient temperature, taking into account effects such as frost, the choice of temperature is 10 ℃. ? t is a ~ 12 ℃. t determine the temperature of the heat storage medium,[link widoczny dla zalogowanych], according to the aforementioned selection Halo ・ 10H = O, the phase transition temperature of 32 {℃. If the selected temperature 7.4 ℃, then tt = 25 ℃. In addition, the selected temperature is too cold, \load on the Qm = 58.5kw cold heat accumulator over a 6kW Q-cycle O-t ring split ratio m / m heat capacity of a condenser Qc 0.509 a 135kW heat through the evaporation of business Q *= 59kw heat absorption cycle theory COP - 5.7t. 【 j in the number of strongly prime. The COP is the actual process can not achieve such a high. as in different temperatures to calculate the ring} mullet of three links split ratio,[link widoczny dla zalogowanych], three-way valve can be set to the number of files, and also to a certain temperature so that the switch to achieve the purpose of regulation. VI application prospect of regenerative heat pump heat storage accumulator ever happen} in essentially as a subcooler treatment, thereby improving the operation of the system of myeloid factor. and in harsh temperature environments, through the release of heat. reduce the load on the evening-room, improved working conditions. In addition, the use of regenerator, can reduce the equipment, and make as much as possible to set up the full load operation. It is worth mentioning that, if the accumulator in the additional heating wire - heat storage area can quickly make up for deficiencies. while the other - aspects. more importantly, heard in the night like the cheaper electric heat accumulator in order to facilitate the next day when the day of the operation. to shift peak load. At present, widely used in the case of heat pumps, thermal storage can be plastic, such as heat pumps application. will be able to save energy, call the small power consumption,[link widoczny dla zalogowanych], and to give an example of heat pump units can be increased, reducing the liquid refrigerant into the compressor to the possibility of reference 1.
