Ground source heat pump how many degrees can be reached in winter and summer

First of all, according to the requirements of national regulations, the comfortable temperature of the first level of residence is 24 26 in summer and 18 21 in winter. The ground source heat pump system can fully meet the above needs, and the temperature is no different from ordinary air conditioning and floor heating. In particular, it should be noted that in extreme weather conditions, such as when the outdoor temperature is above 40 in summer and -5 in winter, the ground source heat pump system is not affected by the ambient temperature because of the heat exchange through the underground soil, and the ground source heat pump effect is more stable than that of ordinary air conditioning and floor heating.

National standard ground source working conditions, 7 12 in summer, 40 45 in winter. Normal operation, if the outdoor buried pipe is sufficient, the water supply in summer 7, whether air conditioning or dehumidification is enough, the minimum is 5-6; In winter, it generally burns to about 50, which is no problem, but it hurts the machine; Hot ** Hot water up to 55. It also depends on what brand and what refrigerant is used by the host, and the above are all R22.

Boda microwave, look!

The ground source heat pump Trane main engine is designed to have a temperature of 12 degrees Celsius in summer. In winter, the water outlet factory sets the temperature at 41 degrees. Domestic hot water is 4 degrees. are adjustable.

Shandong Zhongrui New Energy: The ground source heat pump system can meet the conventional interior design temperature, which can reach 24-26 in summer and 18-22 in winter.

Although the indoor temperature is determined by various factors such as outdoor temperature, refrigeration and heating of indoor air-conditioning equipment, thermal insulation coefficient of room envelope structure, cold bridge partition, etc., the ground source heat pump has good operating conditions and high energy efficiency ratio; Under the same conditions, compared with conventional air conditioning systems, ground source heat pumps can make indoor comfort more efficient.

The system is an underground loop filled with water that circulates through the pipes under the power of a pump. At the same time, in summer, the water in the pipeline will bring the indoor heat into the underground soil through the main water pump, which realizes the cooling of the indoor environment and achieves the effect of refrigeration; In winter, the heating cycle is realized; It has a domestic hot water function all year round. Then this underground pipe system is a closed circulation pipeline, at the beginning of the commissioning has been injected into the pipeline and pressurized to the working pressure state, in normal operation because it is a closed operation, there will be no leakage, so there is no water consumption, and there is no need to use tap water to the ground Min Wei to make the buried pipe system water.

2. Ground source heat pump ** air conditioning indoor load measurement system.

In summer, this system continuously sends the cooling capacity produced by the main engine to the end of the room through the water pump in the water, so that the indoor temperature is reduced and meets the requirements; In winter, the heat taken by the main machine is transported to the end of the chamber to achieve the purpose of heating. This indoor system will also use water, but the water used in it is the same as the underground pipe system, it is also a closed cycle, and there is almost no water consumption in the basic normal operating state, so there is no need to replenish water into the pipeline system. However, when the system is running in the summer or winter season, there will generally be an exhaust step, that is, the indoor unit is running, and the air valve of the bridge bureau is opened to discharge the air in the pipeline to achieve better results, this process requires some water consumption, but the amount is very small, that is, the water brought out during exhaust.

In short, regardless of whether it is winter or summer, the ground source heat pump system does not need to consume water all the time. Of course, if the unit needs to be shut down for maintenance, or cleaning, then it needs to be filled with water at one time and pressurized to the working state, and the water required is the amount of water required to fill the pipeline, and that's it.

The ground source heat pump heats the cooling water in winter and goes indoors, because the pipe is installed indoors

Summary. The air source heat pump heats up quickly, heats quickly, and a good radiator starts to dissipate heat after 10 minutes of opening, and reaches the preset temperature (20 2) in half an hour. In addition, it is ready to use, so there is no need to wait, saving time.

The replacement is also simple, and it can directly replace the original boiler heat source. Compared with direct electric heating, the energy saving effect is significant; Compared with the electric boiler heating method, the cost of power capacity increase is saved. You can rest assured.

Hello! I've kept you waiting. I've seen this kind of heating system.

Under normal circumstances, it can reach about 20 degrees in summer and 25 degrees in winter.

For ground source heat pumps, a constant temperature of 25 degrees throughout the year is the most comfortable.

At the same time, it can also provide domestic hot water all year round, which is very energy-saving.

With a ground source heat pump system, the thermal balance of winter and summer must be considered. Now the common practice is underground pipe + cooling tower.

To put it simply, the heating load is used as the main basis for the calculation of the buried pipe, and this part of the buried pipe mainly meets the requirements of the heating load in winter and the cooling and heat dissipation in summer, because the heat dissipation load in summer is larger, and the insufficient part is borne by the cooling tower, so that it can meet the different load requirements of winter and summer, and can also avoid the situation that the soil temperature rises and the cooling effect deteriorates after several years of operation.

For example, in East China, when heating begins in winter, the temperature of underground water is about fifteen or six degrees, and the heating energy efficiency is still good at this time, but if you go further north, the temperature of underground water may only be five or six degrees, and the efficiency is naturally not very high at this time. In the case of refrigeration, the outlet water temperature generally does not exceed 30, so the system efficiency will be better.

However, if the balance between cold and heat is not well designed, the cooling effect will deteriorate after a few years.

You are confusing the concepts of "energy efficiency ratio" and "heat production".

The concept of energy efficiency ratio refers to the ratio of the output energy of the air conditioner to the input electricity.

The same type of air conditioner, including the ground source heat pump, does produce more heat in winter than in summer. However, the electricity consumption in winter is also greater than that in summer. Therefore, the "energy efficiency ratio" must be greater in summer than in winter. This applies to all air conditioners, not just ground source heat pumps.

For the same building, in Xi'an, the heat needed in winter is almost double that of the cold in summer, so that means that the air conditioner will not be "fully running" at all when it really runs in winter

Let's also talk about the so-called "energy efficiency ratio":

The same as the fuel consumption reported by the automobile manufacturer, it refers to the fuel consumption of each car under the same working conditions (fuel consumption at a constant speed of 100 kilometers). This is how it is comparable. And it's not the fuel consumption of the car that really drives like a hungry man.

The parameters of all air conditioners are also compared according to the unified working conditions of the national standard. For example, the standard working condition of air-cooled heat pump air conditioner in summer is the outdoor temperature of 35 and the outdoor temperature of 7 in winter; The standard working conditions of ground source heat pump air conditioner are the parameters calibrated when the outdoor side temperature is 30 in summer and 0 in winter.

Therefore, the "energy efficiency ratio" should be calculated under this working condition. Of course, the ground source hot slag return pump has "suffered" a lot.

1. Add antifreeze in time.

In order to ensure the stable and normal operation of the ground source heat pump throughout the winter, it is very important to do a good job in the anti-freezing work of the unit. Most ground source heat pumps will automatically turn on the antifreeze function when the temperature is low in winter, which must be automatically turned on when the ground source heat pump is energized, so the premise is to ensure that the ground source heat pump is in a state of power.

If the ground source heat pump does not drain the water in the unit during the use of winter, antifreeze must be added, otherwise it will cause harm to the ground source heat pump unit.

2. Special attention should be paid to the damage to the air conditioning system caused by power failure, lack of water or improper use of the ground source heat pump in winter, so as not to affect the normal use.
