2.6 a building area of 100000 m \"the design of the residential area

Is - the need to install the central air conditioning of the area, a high-grade building village, every minimum floor area of over 120 m '. For high-grade body curtilage, the utilization rate of housing and living prime minister should have lower * residents living in the high-grade residence, or a two people, there are several bedroom, in the case of no relatives and friends to visit, can only live in a room, other rooms are at a loose end. Sometimes outdoor travel and the whole house all words. If USES unified central air-conditioning system, both the residence and the idle idle room heating, this not only increases the heat loss, residents also increase factory air conditioning costs. In addition, when heating in winter, because the indoor fan coil system is used, if the heating system can not provide hot water in a row, users do not know when circulation system to stop heating, and users are still in the running of fan coil motor, not only can't heating at this moment, but give a person the sense - · kind of blow a cold wind. If the circulating water pump continuous running and increase the power consumption of circulating water pump, also can cause the electricity waste. So, in selecting the design scheme, consider adopting household central hole system, so also facilitate management. Users according to the requirements of their own freedom to control the temperature of the room, families according to how much to pay electricity, electricity to save the user's heating costs. As the seat of F water supply is not very enough, so consider using groundwater as a source of heat and cold water loop heat pump systems. For 2-6 is the flow chart of the system.

Every body in the system to install a pro-independence eight water source heat pump units, and each unit installed - \"independent pipeline pump. When the user need refrigeration or heating, chain operation c woven water source heat pump and pipeline pump water source heat pump heating, heat absorption in the system, make the system in the circulating water temperature drop, book after energy storage heat sink in the circulating water, and energy storage heat to heat the water in the pool, the system in the circulating water temperature increases, to ensure that every water source heat pump units, often run F. Save energy storage heat sink temperature drops to a certain temperature, the energy storage heat sink temperature sensor, send usd to submersible pumps, submersible pumps and gu to supply water to the water in the pool, make the increase of temperature in the tank, when the temperature inside the tank reaches the specified value, the submersible electric pump will be automatically closed. Stop water supply: when to energy storage heat sink water. Low temperature water in the pool to automatically back Zi and c

In the groundwater is very abundant, and F water. Under the condition of high temperature liquid with water circulation system. But if the underground water is not done enough or underground water temperature is lower, the liquid in the circulatory system is second 2 drunk solution should be adopted: this time for the 100000 m 'village Liu Zhong used in the ethylene glycol solution.

Area of groundwater temperature of 15 ℃, groundwater ChouQuLiang for 250 M '/ h: the whole village in the middle of the string of adjustable running at the same time to delete the largest system capacity of 8 kw, water source heat pump woven c () of the P value is 41. At this point, should be from a to F water 8 delete Lw M (4.1-1) / 4.1 = 6 n8lw heat * fact, for the selected heat exchange system actual heating capacity of the unit could not just equals the need to heat the room. So, higher international heating ability of the selected unit 1: construction of the heat, when the cold water source heat pump units in the community to the probability of column operation was 70%, which means the actual BuYu from plant to heat the water to get part of the value of 6048 kw x 70% = 4234 lw c

Due to groundwater supply) 250 m 'son, I even will have to send to back to D Wells, can provide heat to reach 250 m' eight M15 ℃ M1.163 kW. H/(m '. ℃) : 436 TKW. In fact can't nJ to 0 Y of the water in the pool, maximum control in 2 Y, that is only 250 m 'son x (15-2) I: x1.163 kw · V (m', Y) : 3780 kw. Obviously the groundwater supply, this needs with the help of energy storage heat sink can miao.

Assume that using energy storage pool num energy storage function, the water temperature dropped to 211 when the discharge energy storage heat sink, in the coldest time system of P/water demand for 4234 kw / 2 (15-2) Y x1.163 kw \"V (mj. Y) [= 280 m 'eight l, such short hours of groundwater water deficit of 280 m/h - 250' m '/ h = 30 m/h, if in the low temperature of the system under the condition of continuous running for 10 days, so the volume of energy storage heat sink

House a big j: 30 m xN '/ h x 24 h = 7200 mj. The pool size is too big. Obviously in the village built in such a big pool of water is not realistic to:

Hinder to consider from a different Angle, we use a water ice phase change energy storage, assume that will be part of the water into ice oY, 1 M/h 'groundwater can release heat is (1 t x15Y x1kkc. V ([ten lt x, Y) 80 kkcayt) x1.163 kw. Vkkcal = U0kW. H, and 1 M/h' water heat from 15 ℃ to 2 neon release is 1 M/h 'M (25, 2) Y x1.163 kw' V (M, Y) = 15 kw. Love small hard to see that use a water ice storage can greatly reduce the volume of energy storage heat sink. A water ice phase change energy storage can make the volume of water to 72 mm: x15Lw / 110 kw; 982 NLJ, by J: the density of ice is about 9 kg/o m5, in addition to consider ice monohydrate heat exchange of space, the heat exchange tube within the energy storage heat sink of the volume, so the volume should be appropriate increase point of the pool.

Say here is that the maximum heat load of the building for 10 days free run hypothetical situation, under the fact it is not possible, L is the thermal load of building in one day and constantly minimization algorithm, only in the morning, the heat load of building in order to achieve the maximum average heat load of c - 'day actually less than 20% of the maximum heat load. For just mentioned 10 m 'residential area of the pool water storage capacity can be appropriately to reduce * for factory a building at the same time choosing energy storage heat sink capacity, but also to the percent of water supply enough water deficit, the greater the proportion of water to choose the greater the volume of energy storage heat sink.
