Embodiment Construction

[0021] see figure 1 ,Such as figure 1 As shown, the balance tank 4 is a tank-shaped container processed by TP2M copper pipe, and the inner diameter of the inlet is D 1 Generally 3mm to 7mm, the outer diameter of the cavity is D 2 Generally, it is 20mm to 40mm, the length L is generally 100mm to 150mm, and the wall thickness of the container is 0.5-1.0mm.

[0022] In this example, D 1 5mm, D 2 is 30mm, the length L is 120mm, and the container wall thickness is 0.8mm.

[0023] The calculating formula of the internal product V of described balance tank 4 is: V=M / (ρ 1 -ρ 2 ), in the formula, ρ 1 Density of refrigerant in liquid state, unit kg / m 3 , ρ 2 Density of refrigerant in gaseous state, unit kg / m 3 , M is the poor quality of the refrigerant circulating in the system during cooling and heating, in kg.

[0024] The mass difference M of refrigerant circulating in the system during cooling and heating ranges from 50-250 g, preferably 100-200 g.

Abstract

The invention provides an air conditioning refrigeration circulating system and an air conditioner, which can solve the problem brought by different coolant demand quantities by refrigeration and heating cycle in the prior art. The technical scheme is as follows: the air conditioning refrigeration circulating system comprises a compressor, a condenser, a four-way valve, a throttling device and an evaporimeter, wherein all components are connected by an online pipeline; the air conditioning refrigeration circulating system is also provided with a balance tank which is communicated with the outlet tube of the condenser via pipelines; and the body of the balance tank contacts with the E tube of the four-way valve. The invention utilizes the principles of degree of supercooling and degree of superheat, parts of coolant are stored in the balance tank during refrigeration circulation without participating in the refrigeration circulation, and parts of coolant participate in the refrigeration circulation during heat generation so as to obtain the purpose of balancing the filling amount of the coolant for refrigeration and heat generation.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration engineering, and in particular relates to a new type of refrigerant balance tank for household air-conditioning and the design of an air-conditioning system using the device, and relates to a high-efficiency air-conditioning refrigeration system that adopts the principle of supercooling and superheating to achieve balance. / Device for refrigerant charge during heating. Background technique [0002] The amount of refrigerant injected into the air conditioner plays a very important role in performance indicators such as the energy efficiency ratio and heating capacity of the air conditioner. Due to the differences in the refrigeration and heating cycles, there are differences in the optimal refrigerant injection amount for the two. The difference between the optimal refrigerant charge for cooling and heating of high-efficiency air conditioners is even greater. Usually, t...
